HIV Type 1 (HIV-1) and simian immunodeficiency virus (SIV) display differential replication kinetics in macrophages. This is because high expression levels of the active host deoxynucleotide triphosphohydrolase sterile α motif domain and histidine-aspartate domain–containing protein 1 (SAMHD1) deplete intracellular dNTPs, which restrict HIV-1 reverse transcription, and result in a restrictive infection in this myeloid cell type. Some SIVs overcome SAMHD1 restriction using viral protein X (Vpx), a viral accessory protein that induces proteasomal degradation of SAMHD1, increasing cellular dNTP concentrations and enabling efficient proviral DNA synthesis. We previously reported that SAMHD1-noncounteracting lentiviruses may have evolved to harbor RT proteins that efficiently polymerize DNA, even at low dNTP concentrations, to circumvent SAMHD1 restriction. Here we investigated whether RTs from SIVmac239 virus lacking a Vpx protein evolve during in vivo infection to more efficiently synthesize DNA at the low dNTP concentrations found in macrophages. Sequence analysis of RTs cloned from Vpx (+) and Vpx (−) SIVmac239–infected animals revealed that Vpx (−) RTs contained more extensive mutations than Vpx (+) RTs. Although the amino acid substitutions were dispersed indiscriminately across the protein, steady-state and pre-steady-state analysis demonstrated that selected SIVmac239 Vpx (−) RTs are characterized by higher catalytic efficiency and incorporation efficiency values than RTs cloned from SIVmac239 Vpx (+) infections. Overall, this study supports the possibility that the loss of Vpx may generate in vivo SIVmac239 RT variants that can counteract the limited availability of dNTP substrate in macrophages.

Lys234 is one of the residues present in class A β-lactamases that is under selective pressure due to antibiotic use. Located adjacent to proton shuttle residue Ser130, it is suggested to play a role in proton transfer during catalysis of the antibiotics. The mechanism underpinning how substitutions in this position modulate inhibitor efficiency and substrate specificity leading to drug resistance is unclear. The K234R substitution identified in several inhibitor-resistant β-lactamase variants is associated with decreased potency of the inhibitor clavulanic acid, which is used in combination with amoxicillin to overcome β-lactamase–mediated antibiotic resistance. Here we show that for CTX-M-14 β-lactamase, whereas Lys234 is required for hydrolysis of cephalosporins such as cefotaxime, either lysine or arginine is sufficient for hydrolysis of ampicillin. Further, by determining the acylation and deacylation rates for cefotaxime hydrolysis, we show that both rates are fast, and neither is rate-limiting. The K234R substitution causes a 1500-fold decrease in the cefotaxime acylation rate but a 5-fold increase in kcat for ampicillin, suggesting that the K234R enzyme is a good penicillinase but a poor cephalosporinase due to slow acylation. Structural results suggest that the slow acylation by the K234R enzyme is due to a conformational change in Ser130, and this change also leads to decreased inhibition potency of clavulanic acid. Because other inhibitor resistance mutations also act through changes at Ser130 and such changes drastically reduce cephalosporin but not penicillin hydrolysis, we suggest that clavulanic acid paired with an oxyimino-cephalosporin rather than penicillin would impede the evolution of resistance.

Wisdom to my mind is a bit of a paradox. It is subjective and context-dependent, but inherently universal. I say this, because for something to be wise it ought to be applicable across time and space, yet whether the claims are appraised as being “wise” hinges on the perception of a past, present or future audience. It is beyond the self, yet dependent upon the self. So that then begs the fantasy writing question: What if the self is not human? If culture already morphs the form and substance of wisdom, what effect might a different state of being have on it?

That would be terribly dull to prescribe, but I can help get some readers’ creativity going. Below I have listed relevant questions with examples you might consider when building your setting, so you may merrily thread into your fantastic realms to shape oddities rich and strange.

I would advise readers of this article to try and let go of their own presumptions on what is wise for the sake of worldbuilding. There are few cultures in our modern, human world whose philosophers deem obtuse narcissists dressed in mink robes as being wise, but why wouldn’t a race of bobcat-folk?

The Chatham House Centenary Award winners announced News release jon.wallace 29 July 2021

Black Lives Matter, Greta Thunberg and Sir David Attenborough have been recognized for their achievements tackling racial inequality, climate change and biodiversity loss.

As Chatham House wraps up its centenary activities, the institute has made three Centenary Awards recognizing outstanding contributions to confronting the critical challenges facing the world today.

The awards are unique as they were voted on by the institute’s staff and pay tribute to the individual or organization they believe has played a significant role in progressing the Chatham House mission: to help governments and societies build a sustainably secure, prosperous and just world.

Greta Thunberg has been awarded the Chatham House Centenary Changemakers Award in recognition of her vanguard role in mobilizing young people to take up climate activism.

Greta’s message has cut through where politicians and scientists have failed time and time again. She has commanded the attention of world leaders, addressed intergovernmental organizations and inspired millions of people to join the global climate strike. She has demonstrated the electrifying power of young voices speaking truth to power and focused the world’s attention on environmental injustices.

Sir David Attenborough has been named as the Chatham House Centenary Lifetime Award winner for his tireless commitment to conservation and raising public and political awareness of the growing climate crisis.

Together with the BBC, he has pioneered the way in which we experience and understand life on this planet, bringing the wonders of the natural world into our homes. Over the last 60 years, from black-and-white to 4K TV, his pioneering documentaries have been broadcast around the world and have sounded the alarm on the devastating impact humanity has had on the environment.

He has become one of the most compelling voices on important issues such as biodiversity loss, climate change and the destruction of natural habitats. Sir David was previously awarded the Chatham House Prize in 2019 for his work on Blue Planet II and tackling ocean plastic pollution.

Melina Abdullah, one of the co-founders of the Los Angeles chapter of the Black Lives Matter movement and co-director of Black Lives Matter Grassroots, has accepted the Chatham House Centenary Diversity Champion Award on behalf of the movement.

This award is in recognition of the momentous work Black Lives Matter has done towards empowering black people and promoting a more inclusive approach to race in policy-making. The movement has brought global attention to systemic injustice against black lives and is helping to build a better world that draws on more diverse voices and inclusive approaches.

Dr Robin Niblett, Director of Chatham House said:

‘We are delighted to recognise three special centenary awards today in recognition of the individuals who our staff believe are redefining the ways in which each of us can drive positive global change.

‘The vision and achievements of each of the winners echo Chatham House’s own goals for its second century and demonstrate a shared commitment to building a more sustainable and inclusive world.

‘We are inspired by the ways the award winners are leading global efforts to combat climate change, protect biodiversity and bring about more equal and inclusive societies.’

Cross-border conflict, evidence, policy and trends (XCEPT)

This five-year policy-focused research programme seeks to respond to the challenges of long-term cross-border conflicts by exploring the drivers behind them.

Protracted conflicts in the Middle East and North Africa, Horn of Africa and parts of Asia, although usually arising from intra-state disputes, rarely remain contained within national borders. Their effects reverberate outward and external actors are drawn in.

The longer these wars last, the more difficult they are to resolve as the interests of international actors collide and the web of economic and political interactions which sustain violence and connect conflict across borders expand and deepen.

The Cross-border conflict, evidence, policy and trends (XCEPT) research programme brings together world-leading experts to examine conflict-affected borderlands, how conflicts connect across borders, and the drivers of violent and peaceful behaviour.

Chatham House provides research leadership to the programme, as part of the wider consortium, and our research explores:

• the intersection of conflict supply chains which sustain and embed violence
• coping supply chains for survival-based economic activity which occurs in the context of violence

Three geographic case studies will be supported by cross-cutting workstreams on gender and social inclusion, livelihoods, and border security. Each will produce analysis and recommendations to inform international policy responses to conflict across borders.

These case studies will focus on:

• armed actors and financial flows through Iraq and the Levant
• human smuggling across Libya, East and West Africa
• gold mining and weapons flows across Sudanese borderlands

The consortium is made up of a range of other organizations, including the Asia Foundation, the Malcolm H. Kerr Carnegie Middle East Center, the Rift Valley Institute, Chemonics UK and King’s College London.

XCEPT is funded by UK Aid from the UK government.

Professor Sir Laurence Martin (1928-2022) News release NCapeling 3 May 2022

Professor Sir Laurence Martin, director of Chatham House from 1991-96, has died aged 93.

Professor Sir Laurence Martin was one of the UK’s leading experts on international security with a particular interest in nuclear strategy.

Before joining Chatham House, he was Professor of War Studies at King’s College, London and Vice Chancellor of Newcastle University. He was also appointed Deputy Lieutenant of Tyne and Wear as well as holding several distinguished professorships.

His most well-known work was Two-Edged Sword: Armed Forces in the Modern World which was also the subject of the BBC’s Reith Lectures he gave in 1981.

Sir Laurence led Chatham House as the world was entering the post-Cold War era, a time when international relations were in a state of flux which, as he wrote in International Affairs, provided grounds for optimism that ‘the objective conditions exist to eliminate violent and mutually harmful conflict at least between the major powers’.

Professor Martin worked hard to ensure the financial sustainability of the institute following the loss of core funding from the UK government in the 1980s. By modernizing its approach to fundraising, he was able to invest in a much-needed refurbishment of the House, as well as the institute’s first foray onto the internet.

This enabled Chatham House to communicate with new audiences beyond its members, event attendees, and readers of printed reports, The World Today magazine, and International Affairs journal. He paid particular attention to the need for the institute to communicate its ideas to those making policy as well as wider audiences.

In addition to strengthening the institute’s research, he was keen to continue engaging its members in discussions to develop a well- informed understanding of international affairs.

On the 75th anniversary of Chatham House in 1995, he wrote that its role was ’providing the evidence and, above all, encouraging the habit of mind, to facilitate prudent, if possible optimistic, but never utopian judgements about world affairs’. Today’s staff would agree this role remains at the heart of delivering the institute’s mission.

Health not independence is focus for Sturgeon successor Expert comment NCapeling 15 February 2023

Nicola Sturgeon’s star may have been fading, but Rishi Sunak and Keir Starmer will be relieved at the exit of one of the UK’s most influential politicians.

Nicola Sturgeon has left at the right time, maybe even a bit late. Although one of the most influential politicians the UK has seen in recent times, she was also one of the most divisive.

Her ability to fan Scotland’s sense of difference from England brought new hope to the independence movement, but this cause – by which she measured herself above all others – has been losing ground and for now, looks to be in abeyance.

Neat and disciplined, Sturgeon could not have presented a greater contrast to Boris Johnson in the first months of the pandemic. That was one of her finest moments.

She used the powers of the devolved government to make different lockdown decisions for Scotland – never all that different from those in England but often announced just a few hours earlier.

Although analysts surmise that these made little difference to the death rate – although poverty and other health support factors make comparisons hard – she used the platform, with the cameras on her, to ram home the point that Scotland could set its own rules.

Rallying young voters to independence

Her second greatest moment was in the aftermath of Brexit. Scots voted overwhelmingly to stay in the European Union (EU) and so, she argued, they should have the right to leave the UK to join that other union. Younger voters in particular responded, rallying to the independence cause.

But two recent setbacks showed her star was fading. She lost the Supreme Court battle to hold a second independence referendum in November, when she was told Scotland simply did not have the powers to hold one on its own if Westminster said no – and the UK government did just that. It was hard to see how her campaign for independence could move forwards.

And her planned reforms to the gender recognition process in Scotland have been blocked by the UK government – but unease about her reforms within Scotland meant this rebuff did not win her the support at home she hoped for. She was also accused of playing politics by pressing ahead with unpopular reforms simply because of their potential to discomfit the UK government.

Health, education, and public services need attention

Other challenges were also building up and, even if less eye-catching, her successor is likely to focus on health and education above the birth of a new nation. Sturgeon’s critics have long argued that under Scottish National Party rule, health, education, and other public services have declined.

In elections, these factors can be eclipsed by passions about independence but it is rare in political life for a leader to be insulated from public anger on this front. This is almost certainly where her successor will want to focus first.

Independent Thinking: Consequences of the Iraq war Audio NCapeling 23 March 2023

Episode 20 of our weekly podcast marks 20 years since the invasion of Iraq, with special guest Clare Short who resigned from the UK government over the issue.

Launched amid fears that Saddam Hussein was acquiring weapons of mass destruction, the Iraq war changed the Middle East and inflicted huge damage with effects that persist today.

This week’s panel examines the war from the perspective of those in power in London when the decision was made to commit UK forces to the invasion, and with those in Iraq who lived with the consequences.   

Joining Bronwen Maddox is special guest Clare Short, former Secretary of State for International Development, who served in the UK cabinet and resigned after the invasion began, becoming one of the best-known critics of prime minister Tony Blair’s approach to the war.

On the panel from Chatham House is Dr Patricia Lewis, director of the International Security programme, and three members of the Middle East and North Africa programme; the director Dr Lina Khatib, senior research fellow Dr Renad Mansour who is also project director of the Iraq Initiative, and research associate Hayder Al-Shakeri.

Grassroots to global: Young changemakers against violence 24 October 2024 — 3:00PM TO 4:00PM Anonymous (not verified) 11 October 2024 Chatham House

As part of Black History Month, this event will look at how youth activism against violence can influence change.

To address the alarming increase knife crime, a 10% rise in knife-related homicides between April 2022 and March 2023, the UK government launched a coalition of community leaders, campaigners and policy makers to tackle this tragic loss of life.

With people under 25 disproportionately affected, the ‘knife crime epidemic’ represents an example of how youth activist groups are central to tackling the problem. Organisations for and operated by young people form a key part of the strategy to ensure people are better protected from violent crime.

Around the world, a network of youth groups are similarly striving to make a difference and build a better life for future generations. Operating in different political and economic conditions, there are learnings to be found in groups working across the world.

This session will discuss how grassroot activism and youth organisations can influence governments to prevent young people falling into crime, the role of race and religion, and whether organisations are improving in their effectiveness around the world.

This event is a collaboration with Integrate UK.

How Beijing is closing surveillance gaps in the South China Sea The World Today iallan.drupal 15 October 2024

The discovery of a new radar system on China’s Triton Island military base shows that Beijing is rapidly developing its intelligence capacities in contested waters, write John Pollock and Damien Symon.

New satellite images reveal how the Chinese military is dramatically expanding its capabilities on Triton Island, which looks set to become a one of Beijing’s key signal intelligence bases in the South China Sea.

Once completed, the radar system would significantly increase China’s signals intercept and electronic warfare capabilities across the disputed Paracel Islands archipelago and add to a wider surveillance network spanning much of the South China Sea.

The enhanced facility on Triton is likely to offer a challenge to China’s competitors in the region and internationally.

China seized control of the Paracels from Vietnam in a 1974 naval battle, and competition for access to it waters has intensified since the recent discovery of oil and gas reserves. Chinese and Vietnamese maritime militia clashed off the coast of Triton in 2014.

In addition, American, British and Australian naval forces have for the past decade patrolled the waters to collectively challenge China’s contested ‘nine-dash-line’ claim to large stretches of the South China Sea. 

Overlapping anti-stealth network

A year after work was first identified on Triton, satellite images from Maxar have helped build a clearer picture of Beijing’s efforts to defend this strategic waterway.

The most striking development is the construction of a new radar system, known as SIAR – synthetic impulse and aperture radar – which purportedly detects stealth aircraft. The counter-stealth radar on Triton is characterized by its distinctive octagonal structure, which resembles another SIAR system built by China on Subi Reef in the Spratly Islands, south of the Paracels, in 2017. A half-completed tower also sits near the SIAR radar on Triton, which is likely to be the operations centre.

Once completed, the radar on Triton will form what is believed to be a wider network of at least three overlapping counter-stealth radars built across Chinese bases in the South China Sea over the past decade, including on Hainan Island, home to several Chinese naval bases. 

The positioning of the radar on Triton, 320km south of Hainan, is telling, says J. Michael Dahm, Senior Resident Fellow for Aerospace and China Studies at the Mitchell Institute. 

‘SIAR radars cannot see over the curve of the Earth, which means there is a gap in China’s air surveillance coverage between Subi Reef and Hainan Island. The Triton Island site will help close that gap’, said Dahm.

The aim, he suggests, is to give China contiguous counter-stealth radar coverage of the South China Sea.

More construction underway

The satellite images reveal other building projects on Triton. One is a large pad at the end of the road network which will probably be used as a launching point for a mobile anti-ship missile battery. The building at the northeast end of the road is probably a storage building for missile transport vehicles. 

Diminishing Vietnam’s options

The development of a new counter-stealth radar system and other suspected signals intercept structures on Triton represents a notable increase in China’s intelligence capabilities in the Paracels. The Chinese Communist Party has not disclosed the purpose of the building work on Triton, but its effects on regional and global competitors are likely to be wide ranging.

For Vietnam, which is rapidly expanding its own bases in the South China Sea, the intelligence structures on Triton would significantly diminish its capacity to operate undetected in the area. Alongside existing radar on Triton which can detect sea-going vessels, Beijing now has the potential to track Vietnamese air movements and gain forewarning of Hanoi’s manoeuvres in the area, including efforts to access oil and gas deposits.

The desire to strengthen control over these resources may explain why China is fortifying Triton Island, says Bill Hayton, Associate Fellow in the Asia-Pacific Programme, Chatham House. ‘The developments might be a warning that China is planning to mount another drilling expedition’, he suggests.

Sinwar’s death does not make Hamas–Fatah reconciliation more likely, whoever his successor may be Expert comment jon.wallace 22 October 2024

The killing may aid Hamas recruitment – but it will not make agreement with Fatah any easier to achieve.

Western political leaders were quick to argue that Israel’s killing of Hamas leader Yahya Sinwar on 17 October presented an opportunity for a ceasefire in Gaza and the return of Israeli hostages.

US President Joe Biden immediately called on Israeli prime minister Benjamin Netanyahu to seize the moment to negotiate, now that Israel has achieved one of its war aims.

However, that ‘moment’ has already passed. Israel’s military assault on Gaza has intensified since Sinwar was killed, leading UN Peace Process Co-ordinator Tor Wennesland to say that ‘nowhere is safe in Gaza’. It is abundantly clear Netanyahu is intent on further degrading Hamas, resetting a new ‘power balance’ and carving out a buffer zone, no matter the cost in Palestinian lives or Israeli hostages. 

But there are other implications of Sinwar’s assassination beyond the zero-sum analysis of will there or won’t there be a ceasefire.

Hamas’s ability to fight

At present, everyone has an opinion on how Sinwar’s killing will affect Hamas and its ability to resist and respond to Israel’s military. His death will have been a major blow – symbolically, operationally, and psychologically. Hamas has been downgraded and its capacity to respond compromised.

But it will recover, regenerate and retaliate in time – and Sinwar’s death will have been no surprise to Palestinians in Gaza or elsewhere. Hamas is accustomed to seeing its leaders assassinated. Since its formation in 1987, it has been ‘decapitated’ many times, only to continue with its mission to ‘liberate Palestine’.

Hamas’s portrayal of Sinwar dying in his fatigues, head wrapped in a keffiyeh and resisting until the end will persuade many young Palestinians that he died as a martyr serving the Palestinian cause. Many will be inspired to join and fortify the ranks of Hamas as a result.

The IDF’s release of drone footage showing Sinwar’s last moments will have done nothing to undermine his credibility. 

On the contrary, it will serve as a rallying call to disaffected and disenfranchised young Palestinians horrified by Israel’s bombing of civilian targets in Gaza and disaffected with Fatah’s inability to prevent Israeli settler expansion and violence in the West Bank.

Reconciliation

Some hope that if Sinwar is replaced by a more ‘moderate’ leader, his killing may smooth the path to Hamas–Fatah reconciliation – and that this could provide a foundation for a patchwork political solution when Israel and Gaza arrive at the ‘day after.’  

But the idea that a downgraded and ‘leaderless’ Hamas will be susceptible to international pressure to reconcile with Fatah is divorced from reality.  

Prospective new Hamas leaders such as Khaled al Meshaal and Khalil al-Hayya are based in Qatar. 

They may be more pliable to external pressure to reconcile with Fatah in search of a political outcome, but their ability to influence events on the ground in Gaza will be limited. That was demonstrated by the Sinwar-orchestrated attacks on 7 October 2023, which took place without the blessing of the exiled leadership in Doha.

Hamas has long gone to ground in Gaza and become far more decentralized than it was before 7 October. It is now more typical of an insurgency, where Hamas cadres exercise a great degree of operational autonomy.

In other words, the disconnect between Hamas in Gaza and its political leadership in Qatar has only grown wider since this round of conflict started.

International efforts

That will undermine international efforts made by Qatar, Egypt, Saudi Arabia, China, Russia and others to bring about a reconciliation. Moscow and Beijing already hosted reconciliation talks in February and April early this year but made no progress in closing the chasm between the two parties. Saudi Arabia has also hosted talks.

The three Arab states, none of which have so far commented publicly on Sinwar’s killing, will likely view his death as an opportunity to bolster the political wing of Hamas – backing it with pledges of political, diplomatic and financial support.

Saudi Arabia and Egypt will have next to no influence over the succession process, but Qatar’s long-established relationship with the political wing of Hamas affords it leverage over the organization, albeit limited. They may be able to strengthen the hand of those based in Doha by promising to work harder at securing a ceasefire, guaranteeing the provision of humanitarian relief, and working towards a political solution.

Following its snap election, Japanese politics has entered uncharted waters Expert comment LToremark 5 November 2024

Prime Minister Ishiba’s election gamble has failed. Japan now faces another period of political uncertainty, which could affect its international standing.

In Japan’s snap election on 27 October, the ruling coalition of the Liberal Democratic Party (LDP) and New Komeito lost the overwhelming majority it had held since the 2012 general election. The ruling coalition now has 215 seats, leaving it 18 seats short of a majority. 

The largest opposition party is the Constitutional Democratic Party of Japan (CDP), which gained 50 seats to 148. The second largest opposition party is the Japan Innovation Party (Ishin), which lost six seats to 38, and the third largest opposition party is the National Democratic Party (NDP), which gained 21 seats to 28.

But the opposition is divided and there is no real appetite to form a coalition government. This will likely result in a hung parliament, which will further destabilize Japan’s government.

The election results reveal three key things  about the state of Japanese politics and what comes next.

First, that Prime Minister Ishiba’s snap election gamble has failed. The aim was for Ishiba, a non-mainstream member of the LDP, to strengthen the party base and stabilize his administration. But with the ruling coalition losing its majority, the party base has been further weakened and the Ishiba administration is now more likely to be short-lived. LDP voters as well as the public in general  had hoped that Ishiba, as the ‘opposition within the party’, would change the LDP’s structure and government policies, eliminate the uncertainty surrounding party funding and increase transparency on how MPs use public funds to finance political activities.

However, when Ishiba became LDP leader and prime minister, he abandoned his previously more critical stance and prioritized carrying on the policies of the mainstream LDP, leaving his supporters feeling betrayed.

Second, while the ruling coalition has been punished, the people of Japan still did not vote for a change of government. The opposition is divided and, despite its gains in this election, the CDP is not fully committed to take the lead and consolidate the opposition to form a coalition. The CDP also suffers from internal division. The left wing of the party would prefer a coalition with the Communist Party, while the right wing of the party does not want to form a coalition with the LDP or the Communist Party, preferring a partner such as the NDP.

Third, the NDP has become the key to future Japanese politics. By becoming the minority ruling party, the NDP is in a position to control the fate of Ishiba administration. While the CDP has no intention of cooperating with the LDP, the NDP is more willing to do so in order to implement its own policies. As the budget cannot be passed without the NDP’s cooperation, the ruling coalition will have no choice but to accept the NDP’s policy of substantial tax cuts through the expansion of tax credits. It will also likely have to accept an option for married couples to decide their family names, which requires a change of civil codes and is something it has been reluctant to do so far. 

If the NDP’s demands are rejected, a no-confidence motion will likely be submitted and passed, leaving the Ishiba cabinet with no choice but to resign or dissolve the House of Representatives (the lower house of Japan’s parliament).

But the NDP has chosen to not form a coalition with the ruling party and enter government. Why? From the NDP’s point of view, forming a coalition with the LDP, would mean getting involved in the LDP’s internal turmoil – something it wishes to avoid. In addition, elections to the House of Councillors (upper house of parliament) will be held in the summer of 2025. The NDP may have judged that it will have a better chance of implementing its policies by cooperating with the government on a case-by-case basis, rather than forming a coalition with a party that is losing public support and risk following suit.

The minority ruling system that has emerged after the election is extremely rare in Japan’s political history and is likely to make its politics even more unstable in the years ahead. The Ishiba administration will probably be able to survive until the budget is passed in March next year by cooperating with the NDP, but beyond that its prospects are unclear.

As the House of Councillors elections get closer, some in the LDP may say that they cannot fight the election with Ishiba as prime minister. If so, they may choose the option of a same-day election for the lower and the upper house. The cost of an election campaign is significant, and the LDP’s financial strength gives it an advantage in the case of a same-day election. There is also a strong possibility that the public will choose the LDP to regain stability in government. However, this election has shown that public distrust of the LDP is high, and if Ishiba continues to be pushed around by the NDP, his party’s chances of winning would be reduced.

Japanese politics has entered uncharted waters, where the patterns and customs of the past do not apply. There are now doubts both at home and abroad as to whether Ishiba, who has a weak party base, will be able to stay on and steer the government. Over the past decade, the Abe and Kishida administrations have provided Japan with political stability, which has in turn enhanced its international presence. An unstable political system, with frequent changes of government, will likely lead to a decline in Japan’s international influence.

There is also a risk that US–Japan relations  could become unstable. Although the NDP does not have a strong agenda to change the course of this relationship, Ishiba may struggle to keep the promise made by his predecessors to increase defence spending. Ishiba’s nationalist posture could also create a confrontational relationship with the United States, while his weak leadership means he may not seek to invest in strengthening the US–Japan alliance. 

Donald Trump’s win in the US presidential election could pose a further risk. Although Trump might be open to Ishiba’s demand for parity with the US, he could become irritated with Ishiba’s weak domestic position. Ishiba may not be able to make decisions – or a deal with Trump – unless the NDP agrees to it.
