Short breaks in 2015, an uncertain future

Short breaks are among the most fundamental services for supporting families with disabled children. By providing breaks from caring and positive experiences for children and young people, they allow parent carers to focus on relationships with other children, or to have time to themselves or with their partner, leading to lower levels of psychological distress, higher levels of life satisfaction and better health. As a result, fewer parent carers reach ‘breaking point’ and fewer children require access to emergency provision or enter the looked after system. This report, commissioned by Every Disabled Child Matters, looks at the current provision of short breaks to families of disabled children in England.

Vivek Ramaswamy Tells DREAMers To Pound Sand On Mass Deportations

The cruelty is the point with these disgusting excuses for human beings. Maybe they can do something about illegal immigrant Elon while they're at it. The incompetent first Trump administration got their rear ends handed to them during their last attempt to deport all of the DREAMers who were living in the United States under the Deferred Action for Childhood Arrivals program, otherwise known as DACA.

Now they're ready to do it again with Trump's plans for mass deportations, that would destroy the United States' economy.

Trump supporter Vivek Ramaswamy, who could end up with a job in the Trump administration, made an appearance on ABC's This Week, and was asked about whether Trump would actually follow through with his threat or not, and when host Jonathan Karl brought up the DREAMers, who were brought here as children, Ramaswamy basically told them all to pound sand.

KARL: Now, obviously, Trump's promised --and you've talked a lot about this, the -- you know, mass deportation of undocumented immigrants.

Power Shortage To Hit 40% of AI Data Centres by 2027, Gartner Warns

40% of AI data centers will face operational constraints due to power shortages by 2027 as AI drives unprecedented energy consumption, research firm Gartner said on Tuesday. Data center power requirements for AI-optimized servers are projected to reach 500 terawatt-hours annually by 2027, more than double 2023 levels, as companies rapidly expand facilities to handle large language model training and implementation. The surge in power demand will outpace utility providers' ability to expand capacity, Gartner analyst Bob Johnson said, leading to higher electricity costs that will cascade through the AI industry. Some operators are already seeking direct agreements with power producers to secure guaranteed supply.

Reply to Sysel et al.: Comment on the importance of using nitric oxide gas in the synthesis of nitrosylcobalamin and ICH-validated methods to assess purity and stability [Letters to the Editor]

In their comment (1) on our publication (2), the authors make two points: (i) they raise concerns about the possible effect of residual NONOate in our study, and (ii) they promote nitrosylcobalamin (NOCbl) supplied by their own company. Both points lack merit for the following reasons. The authors make the astonishing claim that the spectra of nitric oxide (NO•) and cobalamins overlap. Unlike NO•, cobalamin absorbs in the visible region, permitting unequivocal spectral assignment of NOCbl as reported (3). We demonstrated that whereas NOCbl is highly unstable in solution, it is stabilized by the B12 trafficking protein CblC. So even if present, residual NONOate (which is unstable at neutral pH and is removed during the work-up (3)) could not account for the observed difference.The authors then misrepresent our synthetic method, claiming that anaerobic conditions were used to generate nitrocobalamin (NO2Cbl), which results in the transient formation of NOCbl. We synthesized NO2Cbl aerobically using nitrite as described (4); NOCbl is not an intermediate in this ligand exchange reaction. The aerobic instability of NOCbl has been rigorously described by inorganic chemists (3, 5) and raises obvious questions about its purported biological effects as exemplified by the authors' own 2003 JBC publication, which was later withdrawn.As to promoting NOCbl from their company, the authors refer to a synthetic route from a mixture of NO• gas and aquocobalamin. The authors' method (6) has been described as “dubious” by chemists (5). Whereas DEAE NONOate used in our method is widely known as an NO• donor,...

Comment on the importance of using nitric oxide gas in the synthesis of nitrosylcobalamin and ICH-validated methods to assess purity and stability [Letters to the Editor]

After a thorough read of this paper (1), we wish to clarify that the authors' anaerobic method of synthesis for the production of nitrocobalamin results in the transient formation of nitrosylcobalamin, an unstable intermediate upon exposure to air. We concur that the authors' method results in the production of nitrocobalamin based on the UV-visible data as shown. The authors' adapted anaerobic method consists of mixing hydroxocobalamin hydrochloride with diethylamine NONOate diethylammonium salt in aqueous solution. Of concern, the UV spectrum of nitric oxide overlaps that of all cobalamin species under anaerobic conditions, making any assignments of the binding of nitric oxide to hydroxocobalamin suspect (2). Additionally, the use of acetone to precipitate the authors' product causes precipitation of diethylamine NONOate, resulting in an impure product. As a result, its utility for drawing experimental conclusions is faulty.The product from the authors' anaerobic synthetic method has not been assessed for purity, and the synthetic method itself has not been validated using a stability-indicating method as required by the International Conference on Harmonization (ICH) (ICH Q2B, Validation of Analytical Procedures) methodology, which is a hallmark for analytical characterization. Our nitrosylcobalamin synthesis involves reacting nitric oxide gas with hydroxocobalamin acetate as a heterogeneous mixture in a non-electron-donating solvent followed by rotary evaporation. Our nitrosylcobalamin product is stable in air, releases nitric oxide gas in situ (3), and meets ICH stability guidelines (4). Additionally, our nitrosylcobalamin product demonstrates biological activity, which has not been observed for nitrocobalamin (3, 5).

What is COP29 and why is it important?

What is COP29 and why is it important? Explainer jon.wallace

The COP29 summit will see negotiators try to agree how to finance the climate action the world urgently needs.

COP29, the 29th UN annual conference on climate change, takes place in Baku, Azerbaijan from 11–22 November 2024.

Every COP conference is an important opportunity for international collaboration on climate change. COP29 will have a particular focus on how to make finance available to developing countries for climate action.

COP29 is already contentious, because Azerbaijan’s economy is highly dependent on fossil fuels, the main cause of climate change. That means that Azerbaijan’s government, which will preside over the summit, has a strong incentive to avoid rapid multilateral progress towards phasing out fossil fuels. 

It’s urgent that progress is made at COP29. Climate action lags far behind both what has been promised by countries, and what scientists agree is needed. The impacts of climate change are also rapidly escalating, while backlash against government policies to reduce fossil fuel use is being seen in many places around the world. 

What is a ‘COP’?

The ‘Conference of the Parties’ or ‘COP’ is an annual event that brings together the governments which have signed up to environmental action under the United Nations (UN)

Governments or ‘parties’ attend the climate change COP if they are part of the United Nations Framework Convention on Climate Change, or the international environmental treaties the Kyoto Protocol (1997) or the landmark and legally binding Paris Agreement (2015).

World leaders, ministers, and negotiators convene at the COP to negotiate and rubber stamp plans to jointly address climate change and its impacts. 

Civil society, businesses, international organizations and the media normally ‘observe’ proceedings to bring transparency, accountability and wider perspectives to the process.

‘Mission 1.5°C’ 

COP28, the 2023 climate conference held in Dubai, was the first of three consecutive COP summits intended to ‘reset’ global climate action – what the UN calls the ‘Roadmap to Mission 1.5°C’ – the ambition to keep global temperatures from rising more than 1.5°C above pre-industrial levels. 

To support continuity and progress across the three COPs, the UAE (COP28), Azerbaijan (COP29) and Brazil (COP30) have formed a COP presidential ‘Troika’ or group of three.

COP29 will be the third consecutive COP held in an authoritarian state, and the second consecutive COP hosted by a petro-state. 

In 2023 the first ‘global stocktake’ of international action to address climate change indicated that the world was far off track for targets set by the Paris Agreement. The ‘UAE Consensus’ agreement, which formed the main output of COP28, set out how parties should respond. 

COP29, the second of the three COPs, is intended to get the finance in place to enable this response. COP30, to be held in Brazil in 2025, will then try to agree how a new round of nationally determined climate plans or ‘contributions’ to global climate efforts (NDCs) should be put into action.

COP29 will be the third consecutive COP held in an authoritarian state, and the second consecutive COP hosted by a petro-state. Taken together, the ‘Troika’ hosts make up the world’s 4th largest oil producer, after the United States, Russia and Saudi Arabia. 

This presents both an opportunity and a risk: the countries are well placed to understand and tackle the core issue of fossil fuel extraction and use. But they also have strong incentives to stall, distract and deflect the negotiations away from phasing out fossil fuels.

Key issues at COP29

Finance – money on the table, and a New Collective Quantified Goal

COP29 has a remit to secure funding for a ‘course correction’ on global climate action. Countries’ revised climate plans (NDCs) are due in February 2025. For developing countries to deliver new ambitious NDCs, however, COP29 must first make clear what finance will be available to help them.

The previous climate finance goal of $100 billion per year…was symbolic (being a fraction of the sum actually needed) and contentious.

Climate finance is one of the thorniest issues in the negotiations. The previous climate finance goal, of $100 billion per year from developed to developing countries between 2020-25, was symbolic (being a fraction of the sum actually needed) and contentious (developed countries did not meet the target until 2022, and then only with accusations of double-counting). 

A New Collective Quantified Goal (NCQGs), to be agreed at COP29, will need to reflect developing countries’ needs and priorities. Estimates vary, but it is accepted that the scale will be trillions, not billions. To bridge this enormous gap, private finance will need to be mobilized and broader reforms made to global financial architecture. Issues such as subsidies, fossil fuel profits and ‘solidarity levies’ will also need to be on the table. 

Little progress has been made in the run-up to COP29. Parties disagree on who should pay, how much should be paid, what forms the funding should take (loans or grants) and how the funds should be accessed. 

Also up for debate is how funds should be directed – towards mitigating the impacts of climate change (preventing climate change becoming worse), adapting to its effects, or supporting countries to manage loss and damage (climate impacts that have already happened or cannot be avoided).  

In discussions of the NCQG to date, developed countries have consistently called for higher income developing countries, such as China and India, to contribute. 

Such countries have pushed back forcefully against this. For a new goal to be agreed, such divisions will need to be resolved.

Enhanced transparency?

COPs act as showcases for international agreement, but many processes rumble on behind the scenes. COP29 will be an important moment for transparency under the Paris Agreement, as the Parties’ first Biennial Enhanced Transparency Reports (BTRs) are due in December 2024. 

BTRs are an important tool in the Paris Agreement, requiring countries to provide a snapshot of their progress in cutting emissions, setting climate policies, and providing resources for national and international climate action. 

BTRs are meant to build the evidence base for strong NDCs, build trust and promote ambitious climate action. They are also meant to help developing countries showcase achievements and attract climate finance. 

Azerbaijan…ranks highly on indexes of corruption and has repeatedly restricted space for NGOs and wider civil society actors.

The COP29 presidency has launched the Baku Global Climate Transparency Platform to encourage participation, and support countries in finalising their BTRs. The Platform is meant to provide space for collaboration between government, NGO and private sector stakeholders. 

This is one of the areas in which COP29 host, Azerbaijan, runs into criticism. The country ranks highly on indexes of corruption, and has repeatedly restricted space for NGOs and wider civil society actors through a series of escalating government crackdowns, including imprisonment of environmental activists, in the run-up to the conference.

The Migration-Deportation-Return Nexus

The Migration-Deportation-Return Nexus 6 June 2018 — 1:00PM TO 5:30PM Anonymous (not verified) 23 May 2018 Chatham House, London

In 2015, the unprecedented numbers of migrants crossing borders subjected the EU to extraordinary moral and political pressure, as the number of asylum-seekers soared 122 per cent to 1.3 million people.

In response, the EU has sought to accelerate the deportation of failed asylum-seekers and migrants who arrive without proper documentation. The European Commission has recommended that “all leverage and incentives” be used to “ensure that third countries fulfil their international obligation to take back their own nationals residing irregularly in Europe.”

The Valletta Action Plan, the EU-Turkey deal, the Brussels Agreement with Afghanistan, the EU deal with Nigeria and the new “results-oriented Partnership Framework” signal more restrictive approaches and an outsourcing of the securitization of migration.

However, the EU’s attempt to reconcile its legal and humanitarian obligations with stronger measures has encountered some serious challenges.

This roundtable stimulates dialogue on the circumstances surrounding migrant youth both in Afghanistan and the Edo state in Nigeria, and identifies key questions for further research on the ground.

Contextualising young people’s experiences within a “migration-deportation-return” nexus provides an entry point for the identification of both the commonalities and specifics of the challenges and risks that migrant youth face.

In line with UNICEF’s policy priorities related to children on the move, and initiating global debates in child rights and development, this collaboration forms part of the efforts that seek to inform global research and policy agenda for this most vulnerable of groups under the radar.

The intended outcome of this collaboration is to begin developing a set of core objectives and indicators to help guide the EU, Afghanistan and Nigeria in their treatment of youth, and to facilitate improved donor and host government understanding of the issues.

Participants include experts, researchers, academics, representatives of civil society and governmental institutions.

Attendance is by invitation-only.

The event is co-hosted with UNICEF Office of Research – Innocenti and the University of Cambridge.

Importance of endothelial Hey1 expression for thoracic great vessel development and its distal enhancer for Notch-dependent endothelial transcription [Gene Regulation]

Thoracic great vessels such as the aorta and subclavian arteries are formed through dynamic remodeling of embryonic pharyngeal arch arteries (PAAs). Previous work has shown that loss of a basic helix-loop-helix transcription factor Hey1 in mice causes abnormal fourth PAA development and lethal great vessel anomalies resembling congenital malformations in humans. However, how Hey1 mediates vascular formation remains unclear. In this study, we revealed that Hey1 in vascular endothelial cells, but not in smooth muscle cells, played essential roles for PAA development and great vessel morphogenesis in mouse embryos. Tek-Cre–mediated Hey1 deletion in endothelial cells affected endothelial tube formation and smooth muscle differentiation in embryonic fourth PAAs and resulted in interruption of the aortic arch and other great vessel malformations. Cell specificity and signal responsiveness of Hey1 expression were controlled through multiple cis-regulatory regions. We found two distal genomic regions that had enhancer activity in endothelial cells and in the pharyngeal epithelium and somites, respectively. The novel endothelial enhancer was conserved across species and was specific to large-caliber arteries. Its transcriptional activity was regulated by Notch signaling in vitro and in vivo, but not by ALK1 signaling and other transcription factors implicated in endothelial cell specificity. The distal endothelial enhancer was not essential for basal Hey1 expression in mouse embryos but may likely serve for Notch-dependent transcriptional control in endothelial cells together with the proximal regulatory region. These findings help in understanding the significance and regulation of endothelial Hey1 as a mediator of multiple signaling pathways in embryonic vascular formation.

Cholesterol sensing by CD81 is important for hepatitis C virus entry [Protein Structure and Folding]

CD81 plays a central role in a variety of physiological and pathological processes. Recent structural analysis of CD81 indicates that it contains an intramembrane cholesterol-binding pocket and that interaction with cholesterol may regulate a conformational switch in the large extracellular domain of CD81. Therefore, CD81 possesses a potential cholesterol-sensing mechanism; however, its relevance for protein function is thus far unknown. In this study we investigate CD81 cholesterol sensing in the context of its activity as a receptor for hepatitis C virus (HCV). Structure-led mutagenesis of the cholesterol-binding pocket reduced CD81–cholesterol association but had disparate effects on HCV entry, both reducing and enhancing CD81 receptor activity. We reasoned that this could be explained by alterations in the consequences of cholesterol binding. To investigate this further we performed molecular dynamic simulations of CD81 with and without cholesterol; this identified a potential allosteric mechanism by which cholesterol binding regulates the conformation of CD81. To test this, we designed further mutations to force CD81 into either the open (cholesterol-unbound) or closed (cholesterol-bound) conformation. The open mutant of CD81 exhibited reduced HCV receptor activity, whereas the closed mutant enhanced activity. These data are consistent with cholesterol sensing switching CD81 between a receptor active and inactive state. CD81 interactome analysis also suggests that conformational switching may modulate the assembly of CD81–partner protein networks. This work furthers our understanding of the molecular mechanism of CD81 cholesterol sensing, how this relates to HCV entry, and CD81's function as a molecular scaffold; these insights are relevant to CD81's varied roles in both health and disease.

Ascertaining the biochemical function of an essential pectin methylesterase in the gut microbe Bacteroides thetaiotaomicron [Metabolism]

Pectins are a major dietary nutrient source for the human gut microbiota. The prominent gut microbe Bacteroides thetaiotaomicron was recently shown to encode the founding member (BT1017) of a new family of pectin methylesterases essential for the metabolism of the complex pectin rhamnogalacturonan-II (RG-II). However, biochemical and structural knowledge of this family is lacking. Here, we showed that BT1017 is critical for the metabolism of an RG-II–derived oligosaccharide ΔBT1017oligoB generated by a BT1017 deletion mutant (ΔBT1017) during growth on carbohydrate extract from apple juice. Structural analyses of ΔBT1017oligoB using a combination of enzymatic, mass spectrometric, and NMR approaches revealed that it is a bimethylated nonaoligosaccharide (GlcA-β1,4-(2-O-Me-Xyl-α1,3)-Fuc-α1,4-(GalA-β1,3)-Rha-α1,3-Api-β1,2-(Araf-α1,3)-(GalA-α1,4)-GalA) containing components of the RG-II backbone and its side chains. We showed that the catalytic module of BT1017 adopts an α/β-hydrolase fold, consisting of a central twisted 10-stranded β-sheet sandwiched by several α-helices. This constitutes a new fold for pectin methylesterases, which are predominantly right-handed β-helical proteins. Bioinformatic analyses revealed that the family is dominated by sequences from prominent genera of the human gut microbiota, including Bacteroides and Prevotella. Our re-sults not only highlight the critical role played by this family of enzymes in pectin metabolism but also provide new insights into the molecular basis of the adaptation of B. thetaiotaomicron to the human gut.

Measuring Site-specific Glycosylation Similarity between Influenza a Virus Variants with Statistical Certainty [Research]

Influenza A virus (IAV) mutates rapidly, resulting in antigenic drift and poor year-to-year vaccine effectiveness. One challenge in designing effective vaccines is that genetic mutations frequently cause amino acid variations in IAV envelope protein hemagglutinin (HA) that create new N-glycosylation sequons; resulting N-glycans cause antigenic shielding, allowing viral escape from adaptive immune responses. Vaccine candidate strain selection currently involves correlating antigenicity with HA protein sequence among circulating strains, but quantitative comparison of site-specific glycosylation information may likely improve the ability to design vaccines with broader effectiveness against evolving strains. However, there is poor understanding of the influence of glycosylation on immunodominance, antigenicity, and immunogenicity of HA, and there are no well-tested methods for comparing glycosylation similarity among virus samples. Here, we present a method for statistically rigorous quantification of similarity between two related virus strains that considers the presence and abundance of glycopeptide glycoforms. We demonstrate the strength of our approach by determining that there was a quantifiable difference in glycosylation at the protein level between WT IAV HA from A/Switzerland/9715293/2013 (SWZ13) and a mutant strain of SWZ13, even though no N-glycosylation sequons were changed. We determined site-specifically that WT and mutant HA have varying similarity at the glycosylation sites of the head domain, reflecting competing pressures to evade host immune response while retaining viral fitness. To our knowledge, our results are the first to quantify changes in glycosylation state that occur in related proteins of considerable glycan heterogeneity. Our results provide a method for understanding how changes in glycosylation state are correlated with variations in protein sequence, which is necessary for improving IAV vaccine strain selection. Understanding glycosylation will be especially important as we find new expression vectors for vaccine production, as glycosylation state depends greatly on the host species.

Tsvangirai Leaves an Important Political Legacy in Southern Africa

Tsvangirai Leaves an Important Political Legacy in Southern Africa Expert comment sysadmin 21 February 2018

The story of Zimbabwe’s ‘people’s champion’ offers a powerful example to a region in need of new political compromises.

Supporters hold up a poster of Morgan Tsvangirai during a memorial service in Harare. Photo: Getty Images.

The death of Movement for Democratic Change (MDC) leader Morgan Tsvangirai is a loss for Zimbabwe. In nearly three decades of speaking truth to power, Tsvangirai helped to change his nation and the region.

Southern Africa’s new politics

His death marks a period of transition for regional governments and opposition parties alike. The Zuma era has ended in South Africa while Mozambique, Namibia and Angola have also seen political transitions, pushing modernization agendas to appeal to young citizenries that increasingly see politics in separate terms from the liberationist struggles of the previous generation.

Regional opposition movements also face winds of change: the longstanding opposition leader in the Democratic Republic of the Congo, Etienne Tshekedi, passed away in 2017, and Mozambique’s Afonso Dhlakama and Kenya’s Raila Odinga are both aging. These movements similarly need to appeal to a younger audience or risk losing relevance.

From trade unionist to opposition leader

Tsvangirai’s career is an eloquent illustration of these challenges. Born in Buhera in rural eastern Zimbabwe, Tsvangirai worked in textiles and mining before politics – diverse experience which gave him crucial exposure to the lives of ordinary people across the country. In his early years, he also worked for ZANU-PF, before leaving to forge his own political path. He became increasingly active in mining politics, rising to the executive of the National Mineworker’s Union and, in 1989, to secretary-general of the powerful Zimbabwe Congress of Trade Unions.

In the late 1990’s, Zimbabwe was riven by questions over land, war veterans, the Congo conflict, a shrinking economy and growing doubts about ZANU-PF itself. Opposition leaders of the time could not answer them; those such as Edgar Tekere and Margaret Dongo struggled to win support beyond their local constituencies, and liberation leader Joshua Nkomo’s ZAPU had been merged with ZANU-PF in the 1987 Unity Accord.

But in 2000, Zimbabwe’s ‘perfect storm’ of a divisive constitutional referendum, land redistribution and a June election made Tsvangirai and the newly minted MDC, formed in 1999, a national rival to ZANU-PF. Through subsequent national elections in 2002, 2005, 2008 and 2013, Zimbabwe remained polarized between competing visions of Zimbabwe future: ZANU-PF’s powerful black liberationist politics of identity and the opposition’s equally compelling liberal democracy agenda.

Tsvangirai’s achievement was to provide a credible alternative to liberation icon Robert Mugabe. Tsvangirai also resuscitated Zimbabwe’s tradition of urban nationalism, and was a successor to Benjamin Burombo and other mid-century Zimbabwean urban leaders. Tsvangirai would in turn be a touchstone for contemporary urban activists Evans Mawarire, Linda Masarira and others.

From opposition to coalition

The political struggle for Zimbabwe became global, with Mugabe and Tsvangirai both winning support from rival international power blocs. In March 2007, pictures of a beaten and bloodied Tsvangirai helped to galvanize support for the MDC in the 2008 elections. But the disputed result and violent subsequent run-off between Tsvangirai and Mugabe led the regional community to push both men into a coalition government, with Tsvangirai as prime minister.

Despite continuous ructions, the Government of National Unity (GNU) held, and stabilized Zimbabwe’s collapsed economy, until 2013. Although often politically out-manoeuvred by Mugabe, Tsvangirai deserves credit for getting the opposition a share of political power and for holding his nerve against many who wanted to collapse the GNU.

Tsvangirai was no saint; his complicated love life, and tacit approval of violent attacks on party dissenters, do him no credit. More importantly, the MDC neglected its grassroots supporters during the GNU, and paid the price in its comprehensive 2013 electoral defeat. But although diminished, Tsvangirai remained Zimbabwe’s most popular opposition politician, and the MDC’s new leaders will have quite a task ahead of them, even if they have been planning since his courageous 2016 public admission of colon cancer.

The MDC after Tsvangirai

Nelson Chamisa, one of the three MDC vice presidents, has now been appointed as acting president by the party’s national committee. Chamisa inherits a fractured and fractious party, and one which has also fallen out with the Tsvangirai family. The other two vice presidents, Thokozani Khupe and Elias Mudzuri, have also set their sights on party leadership.

At 40, Chamisa, an orator with grassroots appeal, has a huge task. With general elections due by July, he has to unite the party, counter Zimbabwe’s rising ethno-politics, prove himself as leader of a broader opposition coalition and take on a resurgent President Emmerson Mnangagwa and ZANU-PF.

Electorally, the opposition’s strongest card has always been the urban vote and the economy. But Mnangagwa has fast forwarded a comprehensive economic reform and internationalist agenda. This, and Mugabe’s exit, have forced Chamisa, Joice Mujuru and other opposition leaders to play catch-up. Zimbabwe’s elections, the first since 2000 without Mugabe and Tsvangirai as contenders, will be of global interest as the country navigates the new political dynamics.

The people’s champion

Morgan Tsvangirai’s resilience earned him respect from friends and foes alike, with Zimbabwe’s President Mnangagwa and Vice President Constantino Chiwenga visiting him at home a few weeks ago. A former nominee for the Nobel Peace Prize, Tsvangirai, popularly known by his totem of ‘Save’ and also called mudhara [the old man] deserves national hero status. He will certainly be remembered as the ‘people’s champion’, and a pioneer in bridging the generational and ideological fissures that have shaped Southern Africa’s politics.

With their leader now gone, the turbulent MDC will undoubtedly be hoping for a ‘remembrance vote’ in his memory to carry them through the elections. But beyond that, his story offers a powerful example to a region in need of new political compromises.

The role of think tanks amid political uncertainty

The role of think tanks amid political uncertainty 9 May 2023 — 6:00PM TO 7:00PM Anonymous (not verified) 13 April 2023 Chatham House and Online

Think tank leaders discuss how persistent and new forms of political uncertainty impact on their work and what can they do to counter it.  

Think tanks play a crucial role in supporting better public policy to address the most pressing global and local challenges. However, the recent rise in political turbulence poses a significant challenge to this work. Not only must the work of think tanks help counter political uncertainty but that uncertainty often threatens their ability to work effectively, and in some cases, their survival.

Polarized elections, regional instability, the rise of populism, shrinking civic space, eroding democracies, weakened institutions and public distrust are just some of the tricky contexts and issues raised by think tank leaders in the latest think tank state of the sector report. 

This event is being held in collaboration with On Think Tanks ahead of the On Think Tanks Conference.

Join us for a thought-provoking discussion at Chatham House on the major sources and consequences of political uncertainty in the world today and the critical role of think tanks in responding to and countering it. 

Key questions to be addressed during this discussion include:

  • How does political uncertainty look like today?
  • What can think tanks do to operate within uncertain contexts? 
  • What are their roles: should they build the middle ground, support political parties, rally behind social demands?  
  • Will think tanks be able to maintain their reliability and credibility in an increasingly polarized political environment?
  • What can think tanks do to contribute to greater political stability?

As with all member events, questions from the audience drive the conversation.

A drinks reception will immediately follow this event.

Reshaping NATO for an uncertain future

Reshaping NATO for an uncertain future The World Today mhiggins.drupal 25 May 2022

A Chatham House expert panel outlines the challenges for delegates at the Madrid summit where the roadmap for the transatlantic alliance will be created

This year had already been earmarked as pivotal for the shape and direction of European security even before Russia, a nuclear superpower, rolled its tanks into Ukraine.

On the agenda at the NATO summit in Madrid in June is the Strategic Concept, which sets out the alliance’s direction and priorities for the next decade. There is much to discuss. From shared values to the state of the security environment, the Strategic Concept will have a direct impact on the global security landscape.

Ten years ago, the world was a very different place. The United States had just withdrawn from its bloody war in Iraq and was still embroiled in Afghanistan fighting the Taliban. In China, Xi Jinping was poised to become the next president, while refugees escaping the vicious civil war in Syria were heading towards Europe. In Africa, Islamist activity in Mali was about to spread throughout the Sahel.

Now, Russia’s illegal war in Ukraine rages on NATO’s doorstep, spurring the once neutral countries of Sweden and Finland to seek membership. How will Russia’s aggression towards Ukraine affect the western security agenda and what will be the shape of the new NATO that emerges from these talks?  To help answer these questions, The World Today convened a panel of Chatham House experts to consider what the next 10 years holds for NATO.

Here is what they said.

Alice Billon-Galland
We shouldn’t expect a revolution, but more an adaptation of reforms that have taken place at NATO for quite a long time, especially since the Wales summit in 2014. NATO allies will have to decide on the Russian threat perception and decide how they want to reinforce their deterrence and defence posture in the East, and how this affects their ability to maintain a 360-degree approach and to carry out the ambitious NATO 2030 agenda.

Patricia Lewis
We need to understand how deterrence works far better and we should have better metrics by now. Russia and NATO do not wish to engage in conventional warfare with each other, which suggests that Nato’s conventional deterrence is working. That said, Putin’s nuclear threats have not been within the framework of deterrence. But nuclear deterrence has not worked in the way strategists imagined since the end of the Cold War, and we need a much clearer hard look at these weapons once this is all over.

Had we followed through on disarmament in the 1990s, Putin would have held very little sway today. Nuclear weapons and despots are not a good mix and with these weapons there are no small mistakes. We would be foolish to imagine that rationality will hold when it comes to nuclear decision-making.

It is time to put arms control back on the agenda and strengthen our efforts to prevent nuclear proliferation. We need to put the elimination of these weapons back on the UN Security Council agenda.

Andrew Dorman
Finland and Sweden coming into NATO completely transforms the Baltic. It makes the deployment of reinforcements to the Baltic states an awful lot easier. From the Kremlin’s point of view, the last thing they want is another border with NATO. Russia is already overly committed and hasn’t got enough forces to deal with Ukraine. Its border with Finland is enormous. And NATO would be gaining two very robust, well-organized military forces. You are seeing a lot more NATO assets starting to look at the high north.

Hans Kundnani
I am actually slightly less worried about the Russian threat to NATO countries than I was before February 24. The war has demonstrated how weak the Russian military is, and so the idea that it might present a threat to Finland and Sweden seems less plausible than before. It is not even clear to me that Russia could do very much in other south-eastern European countries. It already seems pretty overstretched. This should make us more relaxed, rather than more worried, about threats to other countries and in particular to NATO countries or to Finland and Sweden.

Leslie Vinjamuri
Sweden and Finland moving forward with their requests for membership is a sign of success for the West, but it also raises important questions for the future of European security. The possibility that we lock in a division that might suit Europe and the United States now does not bode well for a Russia maybe 10 years out or with a different leader.

Alice Billon-Galland
We need to avoid mission creep, but we also need to avoid going back to a position where NATO only focuses on Russia and then set an agenda for 10 years based on that threat assessment alone. We will risk missing out on the next big challenge if we go back on something too specific. We risk being reactive, whereas the Strategic Concept is an exercise that should be proactive and provide a space for transatlantic partners to share broader common security concerns.

Patricia Lewis
NATO is open to all countries in the transatlantic area, and it is even possible that Russia could join in the future should they wish to apply. But it is important to remember that NATO is a political-military alliance, and its politics are fundamental to its cohesion, far more than that of any weapon system or a specific enemy. It will continue to address a wider range of threats as it has in, for example, Afghanistan and many of those will be directly related to the impacts of climate change.

One thing to note, in light of Russia’s nuclear threats, is that NATO’s characterization of itself as a ‘nuclear alliance’ should be revised. NATO needs to be resilient to ebbs and flows of weapon systems and not become over-reliant on one system which has recently demonstrated severe negative impacts.

Hans Kundnani
During the Cold War, what held the alliance together was a shared perception of a threat from the Soviet Union – not a set of shared values. After all, there were authoritarian states in NATO. After the end of the Cold War that overwhelming sense of a shared threat from the Soviet Union disappeared and NATO tried to reinvent itself as a community alliance of democracies with shared values.

But we now once again have authoritarian states in NATO. So it was really in danger of being pulled apart. The war in Ukraine has refocused NATO on its original, historic mission: collective security in relation to Russia. In that sense it has given NATO a lifeline.

Creon Butler
Shared values are still an awful lot stronger as an element of what ties NATO together now than they were in the past. I think you now have the threat perception coming back full force. But I still think you have that very strong element of values, indeed the extra countries that are coming in are very strong democratic countries.

The interesting question is the out-of-area stuff – the Afghanistan-related stuff and counterterrorism more generally, and how important those threats remain. I guess there is an element to that which is a global kind of threat, counterterrorism, but there is also the out-of-area activity which obviously has been transformed following the withdrawal from Afghanistan.

Alice Billon-Galland
The crisis management mandate needs to be looked at again with some of the lessons learnt after Afghanistan and Libya, especially given what happened in Kabul, and all the discussion around cooperative security. The question is not only how do we work with partners and countries in the region, but how do we want to engage with China, for instance? How do we want to work on new technologies? How do we want to work with the European Union, with the United Nations?

The alliance must decide what it wants to do versus  what it wants to set aside and have other organizations do, while it refocuses on its core historic tasks.

Andrew Dorman
One of the sensitive, ongoing debates within NATO is whether it has a global role or whether it has a more transatlantic role. There are divisions within NATO about which is its focus. I think the answer, to a degree, is both. One of the real challenges for policymakers, particularly the Biden administration, is that they are going to be pushing for NATO to act as a global player.

This is one of the dilemmas that NATO faces. It could spend all its time focused purely on the short term – that is Russia –  and ignore China, and then suddenly need to think, ‘Oh heck’. What happens if , as a result of this, Russia is essentially dropped into the China camp and Putin becomes Xi Jinping’s poodle? That is a real dilemma, and why I think the US is going to focus on a global NATO.

Leslie Vinjamuri
NATO may have a role to play in Washington’s China strategy. But it won’t be the most important institution. The Biden administration is relying on multiple frameworks for engaging in the Indo-Pacific. For example, the Quad – a partnership between the US, Japan, India and Australia – is designed to secure India’s participation. Pulling India into the region where it has economic power, influence, military and security capabilities and can move the needle. It is both an intelligent and pragmatic strategy to have a number of groupings, a patchwork of overlapping partnerships, including existing alliances. That seems right to me.

Patricia Lewis
It is unlikely that the US would want to create a global NATO. The US and its allies in other regions may wish to model future alliances on NATO, that have strong relationships with it in areas such as political coherence, interoperability, and joint training and exercises and such. But political decision-making would be better suited to sit within specific regional contexts.

Washington has formal alliances in the Indo-Pacific region that commit the US to, for example, the defence of Australia through the Anzus security treaty, as well as Japan. As Washington increases its focus on the Pacific, the existing political-military relationships in the region could become more coherent. We might see a version of a Pacific-Asia Treaty Organization emerge – a Pato. All this depends on how China uses its power and how perspectives in the region evolve.

Creon Butler
I am not sure it is a problem that NATO does not have a specific focus on dealing with the China threat. It potentially has a role in dealing with those things that are seen by the membership as common threats. Which clearly is Russia now but has added terrorism in the past and may well include other things. China is not a common threat in the way that Russia is perceived to be. Of course, something could happen, not least something with Taiwan, which would change that, but that is not where NATO is at present.

Alice Billon-Galland
I think we should really avoid a false dichotomy between ‘NATO should do only Russia’ and ‘NATO should do everything’ because there are lots of activities in the middle where the alliance can bring some added value – and that is exactly what we should be discussing. The issue around China and NATO is being completely overblown. We need to be very clear that the purpose of NATO is to defend the Euro-Atlantic space, but that may include keeping an eye on ‘when China comes to us’, as NATO Secretary-General Jens Stoltenberg often says.

Hans Kundnani
None of the regional partners in Asia that you need to deal with the China challenge are in NATO – and can’t be – so it is just the wrong vehicle to deal with the Indo-Pacific. But there is also a bit of a tension here between Indo-Pacific and Euro-Atlantic. People in Asia also look at the different threat perceptions in completely different ways than we do in Europe. There are a number of reasons why people in India do not support the war in the Ukraine, but one of them is that they see China, not Russia, as the real threat.

Andrew Dorman
I think so much of the debate we have had so far is about political NATO as supposed to military NATO. One of its key roles is how military forces operate, engage and conduct operations, plan operations through deterrents and so forth. NATO as the template of the West does work. That is why it is in the interest of the US to keep this going. It is one of the ways of making sure, for example, the US Pacific fleet remains compatible with the US Atlantic fleet by forcing them to operate the same system, which is the NATO system.

It is one of the things the American forces learnt out of Afghanistan and Iraq. There is a NATO way which is a global footprint. NATO’s role within the African Union is as a template for peacekeeping operations. You have got the likes of Australia and South Korea and Japan very much integrated into NATO. It doesn’t have to be a formal political NATO, but it does strike me to be in the interest of the West to have them reach forces capable of operating with one another.

Patricia Lewis
One of the most interesting developments in the past year has been the creation of Aukus, the security pact between Australia, Britain and the United States. That grew out of the Five Eyes intelligence partnership which led to the need to develop new, interoperable equipment such as nuclear-powered submarines. We will have to see how it develops, but maybe it could be the start of a PATO in the region.  

Creon Butler
In the current situation, we have a crucial partnership between NATO and the EU over Russia, in terms of the long-term future they hold out for Ukraine, but also with the G7 because that is the place to organize the financial support for Ukraine and the economic and financial sanctions against Russia. They are different memberships but the combination of the EU, G7 and NATO is an absolutely crucial alliance of different alliances, with different memberships serving different purposes but having an overall impact that can potentially be very effective.

Leslie Vinjamuri
We work with the institutions that we have, but not always with a clear recognition of their limitations. We are facing a dark moment for the UN Security Council, with one of its founder members blatantly violating the UN’s most important norm. Yet many people in the rest of the world say, ‘Yes, but in 2003, the United States violated Iraq’s sovereignty …’ Where the West sees moral clarity, and so condemns Russia’s invasion of Ukraine, there is an assumption by much of the rest of the world of moral equivalence between these two invasions.

Working through the UN Security Council is going to be difficult for some time. This means that states are probably going to find different strategies for working around, rather than through, the Security Council.
