Less than four months after ascending the throne, Saudi King Salman bin Abdul Aziz Al Saud has made unprecedented changes in the line of succession that benefit his own son Prince Mohammed bin Salman. These shifts come as Salman pursues the most assertive foreign policy in recent Saudi history.

The king removed the sitting Crown Prince Muqrin, his half brother, and promoted the third in line Prince Mohammed bin Nayef, his nephew, up to number two. Salman made his own son, Mohammed bin Salman, the new number three. The King also replaced the ailing foreign minister, Prince Saud al Faisal with a non-royal, the current ambassador to Washington, Adel al Jubeir. Prince Saud had been Foreign Minister since 1975.

According to the royal palace, Prince Muqrin asked to be replaced, but no reason was given. No crown prince has ever given up the position in the history of the modern kingdom, founded in 1902. When Salman ascended the throne in January, the press trumpeted Muqrin as heir and there was no sign he was not eager to be the next in line. Many will assume he was asked to quit.

Speculation will be intense about why that might be. Muqrin was a protégé of the late King Abdullah. He is not close to Salman's branch of the family, the Sudeiris. He also appeared less enthusiastic about Salman's war in Yemen. As a former fighter pilot Muqrin understands the limits of air power, and he may have had doubts about the wisdom of what was initially called Operation Decisive Storm, but has now become a stalemate.

The new crown prince, 55-year-old Mohammed bin Nayef, is famous for defeating Al Qaeda's violent attempt to overthrow the House of Saud a decade ago. MBN, as he is known, led a four-year counter-terrorist campaign that decimated Al Qaeda in the Kingdom and drove its remnants into Yemen. In the process MBN survived at least four assassination plots. His father, the late Crown Prince Nayef, was so reactionary he was nicknamed the Black Prince. But MBN studied in Oregon and with the FBI and Scotland Yard before joining the Saudi interior ministry. He also holds the position of chairman of the Kingdom’s security and political committee coordinating all security issues.

Mohammed bin Salman, MBS, is the face of the Yemen war. He became defense minister in January and has been constantly on Saudi TV appearing to direct the war effort and meeting with foreign leaders to win support for the campaign against the pro-Iranian Zaydi Shia Houthi rebels. He is considered ruthlessly ambitious and is very close to his father. He has given up his position as chief of the royal court but he will undoubtedly keep control of access to the king.

Unlike most Saudi princes, MBS was not educated in the west. Instead he studied at King Saud University. There is controversy over his age, reputed to be anywhere from 29 to 34 (officially his birthday is July 24, 1980). He is chairman of a number of young people's organizations in the Kingdom and seeks to portray himself as the leader of the next generation of Saudis. He also chairs the powerful development and economics committee that coordinates economic policies, including oil price and supply.

In promoting his nephew and son, King Salman is passing the torch to the next generations of royals. Since 1902 the Kingdom has been ruled by the founder of the modern Kingdom Ibn Saud Abd Al Aziz or his sons. Now, Salman will be the last son to reign.

These changes have all been endorsed by the Allegiance Council, the committee of the sons and grandsons of Ibn Saud, but the legitimacy of selecting the next generation has been a question mark over the succession process for years. The king hopes it is now all settled.

The late King Abdullah's own son, Prince Mitab, has kept his powerful position as commander of the Saudi National Guard. The SANG is the family’s praetorian guard, it defends the capital, the holy mosques in Mecca and Medina and the oil industry. SANG troops have occupied Bahrain, the Kingdom’s tiny island neighbor, since the Arab Spring in 2011 to keep a minority Sunni monarchy in power.

The new lineup is solidly pro-American but riven with doubts about American reliability. The royals believe George W. Bush foolishly let Iran gain dominance in Iraq and fear Barack Obama is too eager for a nuclear deal with Iran and a grand rapprochement with Tehran. Repeated assurances by Obama and concrete support for the Yemen war have not altered Saudi doubts about America.

Salman's decision to wage war in Yemen so soon after coming to the throne reflected his acute concern that Iran was gaining a foothold on the Arabian Peninsula in what has always been the soft underbelly of Saudi Arabia, Yemen. The Zaydi Houthi rebels are not pawns of Tehran but they did initiate direct air flights between Sanaa and Tehran early this year, offered Iran port facilities and negotiated a lucrative oil deal. A few Iranian Revolutionary Guard advisers have been assisting the Zaydis for the last few years covertly. From Riyadh's view Iran already dominated decision-making in Baghdad, Damascus and Beirut, it does not want a fourth Arab capital to be aligned with Tehran.

But Salman's intense effort to secure wide Islamic backing for the war has been less than a success. Oman, Yemen's other neighbor, has opted not to join with the other five members of the Gulf Cooperation Council in the fighting, instead staying on the sidelines. The Pakistani parliament voted unanimously to keep neutral and rebuff repeated Saudi requests for ground troops to aid the war effort. Pakistani officials have privately suggested Salman panicked into the war without a viable strategy to get the Houthis out of Sanaa. Even Egypt, which benefits from billions in GCC aid, has opted not to send troops. although it's navy is supporting the Saudi blockade of Yemen.

The Yemen war is part Saudi-Iranian regional rivalry, part the unfinished business of the Arab Spring revolutions and part sectarian Sunni-Shia animosity. It is above all the Salmans’ war, father and son together. The surprise elevation of MBN and MBS underscores how the stakes in this war are crucial, not only to Yemen's future but increasingly to the future of the House of Saud.

The killing of Nasir al-Wuhayshi, reportedly via U.S. drone strike, is not just another notch in the belt of America’s long campaign against al-Qaida and its allies. Wuhayshi was one of al-Qaida’s top remaining leaders, and he is the highest-level death the organization has suffered since Osama bin Laden was killed in 2011. Wuhayshi headed al-Qaida’s most active affiliate, the Yemen-based al-Qaida in the Arabian Peninsula (AQAP), and was the designated successor of al-Qaida leader Ayman al-Zawahiri. His killing adds one more element of uncertainty to the turbulence in Yemen and may set AQAP on a new path. Which path, however, remains an open question.

Wuhayshi helped transform AQAP from a fractious organization on the edge of defeat to one that menaces both Yemen and the United States. A decade ago, Yemen’s jihadi movement seemed near defeat. In the aftermath of 9/11, the Yemeni government rounded up jihadis and imprisoned Wuhayshi, and it was Saudi Arabia, not Yemen, that was the focus of jihadis in the Arabian Peninsula. In 2003, al-Qaida sponsored the original AQAP’s uprising against the Saudi government. Several years later, most of AQAP’s Saudi members were dead or in jail, and its remnants had fled to Yemen. There, they mixed with Yemeni jihadis, including important figures like Wuhayshi, who had escaped from Yemen’s jails in 2006. In 2009, two regional Islamist groups merged and formally anointed themselves AQAP, basing their operations in Yemen and trying to unseat the government. As Osama bin Laden’s former secretary, Wuhayshi became the group’s leader and embraced al-Qaida’s emphasis on attacking Western targets.

The group made fitful progress, at times taking territory but often losing it quickly after alienating locals and proving vulnerable to government counterattacks. But when the government of Yemeni President Ali Abdullah Saleh fell in 2012 during the Arab Spring, AQAP tried to step into the void. Saleh’s successor, Abed Rabbo Mansour Hadi, pursued AQAP vigorously, but his weak government was unable to score any lasting successes.

In addition to its prowess in Yemen, AQAP has long been al-Qaida’s most active affiliate when it comes to taking on the West. The organization was behind the 2009 Christmas Day attempt to down a U.S. airliner over Detroit, a near-miss only foiled by the bomber’s incompetence and the quick thinking of the plane’s passengers. AQAP tried again in 2010, this time attempting to down U.S. cargo planes. The organization also attacked Western targets in Yemen, and puts out Inspire, a stylish English-language online publication that is one of al-Qaida’s more effective attempts to influence Western jihadis.

These AQAP efforts to attack the United States and the West, in general, led to a greater U.S. focus on Yemen and more drone attacks there. In 2011, the United States killed Anwar al-Awlaki, a U.S. citizen and AQAP member who helped lead the terrorist group’s campaign against targets in the United States and Europe. Awlaki has continued to inspire terrorists after his death, with Boston Marathon plotters downloading his sermons before their attack. Awlaki also inspired the Fort Hood shooter in 2009 and the attacks on the Charlie Hebdo office in 2015.

Wuhayshi’s death, however, comes as Yemen is falling apart. Earlier this year, Hadi’s government fell to the Houthi rebels, Yemeni Shiites who oppose both Yemen’s traditional order and the Sunni fanatics of AQAP who see Shiites as apostates. Alarmed by Houthi ties to Iran, Saudi Arabia has led an intervention in Yemen on Hadi’s behalf, bombing the Houthis and trying to reverse their gains. AQAP seems to be flourishing amid the chaos, as its enemies turn on one another.

But with Wuhayshi’s death, AQAP may find it difficult to further exploit the Yemeni civil war. Personal connections, reputation, and charisma play a bigger role in leadership in the jihadi cause than do formal rank, and it is not clear if Qasim al-Raimi, the designated new leader, can retain the support of the AQAP rank and file. There is always a chance, of course, that Raimi proves an even more effective leader than Wuhayshi, and some observers see him as “more dangerous and aggressive.” (Lest we forget: In 1992, the Israelis killed Hezbollah’s Secretary-General Abbas al-Musawi, one of the group’s most competent leaders. Musawi was replaced by Hassan Nasrallah, who has proven one of the most effective terrorist and guerrilla leaders in modern times.)

The bad news is that Raimi and AQAP may seek revenge, both out of genuine anger and to score points within the jihadi community. Al-Qaida’s chief bomb-maker, Ibrahim al-Asiri, may still be out there and has likely passed his sophisticated techniques on to others in Yemen.

The bad news is that Raimi and AQAP may seek revenge, both out of genuine anger and to score points within the jihadi community.

Over time, however, Wuhayshi’s death may push AQAP to focus even more on Yemen and less on the West. His close, personal ties to the al-Qaidacore may have been part of why AQAP was a steadfast ally of Zawahiri in his power struggle with the Islamic State. The opportunities and risks in the civil war are both tempting and frightening for AQAP. On the one hand, by taking up arms against the hated Shiites, AQAP can position itself as the defender of Yemen’s Sunnis, a strategy that has worked well for the Islamic State in Iraq and Syria. AQAP might gain more recruits and local support, while drawing foreign fighters and money from Sunnis eager to find yet another Shiite-Iran axis to oppose. Not surprisingly, AQAP has stepped up its operations against the Houthis in recent months.

AQAP also has an opportunity to govern. And the bad news for the West is that it has learned from its own many mistakes on this front. In the past when AQAP made gains, it tried to impose a strict version of Islamic law that alienated local communities. Now when its fighters seize territory, theywork with local tribal figures and other elites, avoiding the most controversial measures and trying to portray themselves as guardians, not overlords.

Wuhayshi’s death also comes at a time when the broader jihadi movement is split between backers of al-Qaida and supporters of the Islamic State, a struggle in which AQAP has long played an important role. As al-Qaida’s most active anti-Western affiliate, AQAP was important to Zawahiri’s claim that he was leading the struggle against the United States. Its strength in Yemen, moreover, also expanded al-Qaida’s presence and prestige to an important part of the Arab world. Islamic State supporters have already conducted attacks in Yemen, and the death of Wuhayshi offers them a chance to expand their influence there. The core leadership of AQAP is not likely to join the Islamic State, but some of its cells and supporters could break off if Raimi proves a weak leader.

For now, Wuhayshi’s death means the United States has another point in the struggle against the jihadi movement. In the long term, successful disruption is more likely if the United States and its allies can keep the pressure on AQAP, forcing its leaders to go on the run and hindering their ability to communicate — particularly difficult challenges for a group in transition under new leadership. Wuhayshi’s death also comes on the heels of the deaths of several other AQAP members, including its top ideologue and spokesman. Having to hide also makes it difficult for the group to govern, as its exposed leaders run the risk of being killed. But AQAP has lost many leaders before, yet remains a force to be reckoned with. So at best, this should be seen as winning a battle, not the war.

Event Information

On September 30, 2011, the U.S.-born radical Islamic cleric, Anwar al-Awlaki, was killed by an American drone strike in Yemen, marking the first extra-judicial killing by the United States government against a U.S. citizen. Placed at the top of a CIA kill list in 2010 by the Obama administration, al-Awlaki was known for his intimate involvement in multiple al-Qaida terrorist plots against U.S. citizens, including the 2009 Christmas Day airline bombing attempt in Detroit and the 2010 plot to blow up U.S.-bound cargo planes. His calls for violent jihad remain prominent on the Internet, and his influence has turned up in many cases since his death, including the Boston Marathon bombing of 2013 and the Charlie Hebdo shootings in Paris early this year. In a new book, “Objective Troy: A Terrorist, A President, and the Rise of the Drone” (Crown, 2015), The New York Times national security reporter Scott Shane, drawing on in-depth field research in Yemen and interviews with U.S. government officials, charts the intimate details of the life and death of al-Awlaki, including his radicalization, his recruiting efforts for al-Qaida in the Arabian Peninsula, and the use of drone strikes by the United States to prosecute its counterterrorism goals.

On September 17, the Intelligence Project hosted Shane to examine the roles played by al-Awlaki in al-Qaida plots against the United States, al-Awlaki’s continued influence on terrorism, and the current state of al-Qaida today. Brookings Senior Fellow Bruce Riedel, director of the Intelligence Project, provided introductory remarks and moderated the discussion.

Editor's Note: This piece originally appeared on Lawfare.

The United States began to use drones in Yemen in 2002 to kill individuals affiliated with al-Qaida in the Arabian Peninsula (AQAP) and its predecessor organizations and disrupt its operations there and abroad. Since then, over 200 strikes have killed over a thousand Yemenis, tens of children, and at least a handful of U.S. citizens – one of whom was a deliberate target. The program has drawn widespread condemnation from human rights organizations and some UN bodies, yet it remains in place because the administrations of George W. Bush and Barack Obama view it as a success, as both have publicly stated.

Criticism of the program often takes the form of debates about which legal regime is relevant to judging a state’s use of targeted killings, which critics call “extra-judicial executions” or simply “assassinations.” While dissent has been strongest in academic and human rights communities, some scholars have echoed the arguments made by states that the imperatives of self-defense permit states to carry out such killings as legitimate acts of war. The Lawfare consensus seems in favor of these strikes.

I share the views of the moral and legal dissenters and hesitate to move beyond those debates because I don’t want to suggest that I accept the program’s legality. 

But I do want to engage those who do view the program as working — after all, if the U.S. administration did not believe it was working, it wouldn’t need to justify it legally. But by what metrics should we consider judging its success?

Perhaps the most obvious metric is whether AQAP leaders are actually being killed and, even more, whether their deaths substantially disrupted the group’s activities in Yemen or its ability to pursue objectives outside of Yemen. For advocates of this metric, the program has been successful in the short term — individuals killed – even if the longer-term impact is less clear because new leaders seem to step in with regularity.

Yet the success in taking out AQAP’s leadership is overstated. The numbers of AQAP members and supporters officially reported as killed are questionable, and probably grossly exaggerated. This is because the U.S. administration considers all adult males in the vicinity of the strikes to be combatants, not civilians, unless their civilian status can be established subsequently. Full investigations are neither desirable nor pragmatic for the U.S. government – particularly now that Yemen is the site of a civil and regional war. Even more troubling is that at times the U.S. may not even be certain of its primary targets. It frequently uses language that is so conditional that there seems to be more than a bit of guessing about the identities of those being targeted.

But I would like to focus on different metric: the longer-term impact of the drone strikes on the legitimacy and attractiveness of al-Qaida’s message in Yemen and its ability to recruit among Yemenis themselves. Drone strikes are widely reported in local media and online and are a regular topic of discussion at weekly qat chewing sessions across the country. Cell phone calls spike after drone strikes, which are also widely reported on Twitter and Facebook. The strikes are wildly unpopular, with attitudes toward the United States increasingly negative. An Arab Barometer survey carried out in 2007 found that 73.5 percent of Yemenis believed that U.S. involvement in the region justified attacks on Americans everywhere.

The narrative that the West, and especially the United States, fears the Muslim world is powerful and pervasive in the region. The U.S. intervenes regularly in regional politics and is a steadfast ally of Israel. It supports Saudi Arabia and numerous other authoritarian regimes that allow it to establish permanent U.S. military bases on Arab land. It cares more about oil and Israel than it does about the hundreds of millions in the region suffering under repressive regimes and lacking the most basic human securities. These ideas about the American role in Middle East affairs – many of them true – are among those in wide circulation in the region.

Al-Qaida has since 1998 advanced the argument that Muslims need to take up arms against the United States and its allied regimes in the region. Yet al-Qaida’s message largely fell on deaf ears in Yemen for many years. Yes, it did attract some followers, mostly those disappointed to have missed the chance to fight as mujahidin in Afghanistan. But al-Qaida’s narrative of attacking the foreign enemy at home did not resonate widely. The movement remained isolated for many years, garnering only limited sympathy from the local communities in which they sought refuge. 

 The dual effect of U.S. acceleration in drone strikes since 2010 and of their continued use during the “transitional” period that was intended to usher in more accountable governance has shown Yemenis how consistently their leaders will cede sovereignty and citizens’ security to the United States. While Yemenis may recognize that AQAP does target the United States, the hundreds of drone strikes are viewed as an excessive response. The weak sovereignty of the Yemeni state is then treated as the “problem” that has allowed AQAP to expand, even as state sovereignty has been directly undermined by U.S. policy – both under President Ali Abdullah Salih and during the transition. American “security” is placed above Yemeni security, with Yemeni sovereignty violated repeatedly in service of that cause. Regardless of what those in Washington view as valid and legitimate responses to “terrorist” threats, the reality for Yemenis is that the United States uses drone strikes regularly to run roughshod over Yemeni sovereignty in an effort to stop a handful of attacks – most of them failed – against U.S. targets. The fact that corrupt Yemeni leaders consent to the attacks makes little difference to public opinion.

Regardless of what those in Washington view as valid and legitimate responses to “terrorist” threats, the reality for Yemenis is that the United States uses drone strikes regularly to run roughshod over Yemeni sovereignty in an effort to stop a handful of attacks – most of them failed – against U.S. targets.

The United States cut aid to Yemen in 1990 when the newly united Yemeni state, which had just rotated into the Arab seat on the UN Security Council, voted against authorization for a U.S.-led coalition to reverse the Iraqi invasion of Kuwait. Yemen suffered a tremendous economic blow, as the United States joined Kuwait and Saudi Arabia in unilaterally severing aid to what was then and still is the poorest Arab nation. But with the rise of jihadi activism on the Arabian Peninsula over the next decade, and particularly after the bombing of USS Cole in 2000, Salih welcomed the return of U.S. aid to Yemen. This included a strong security dimension as the United States began tracking those suspected of involvement in the Cole attacks and other al-Qaida activities. Conspicuous caravans of FBI agents became a topic of local conversations, so the return of a U.S. presence in Yemen was also more visible than it had been previously. Salih claimed to have had advance knowledge of every drone strike.

Saudi Arabia has meddled in Yemen at least since the fall of the northern Mutawakkilite monarchy in the late 1960s. The Saudi intervention that began with air strikes in March of this year and escalated to ground troops is thus only the latest — and most egregious — of the kingdom’s efforts to affect Yemen politics. This background is necessary to understand that if Yemen is a “failed state,” despite scholarly protestations otherwise, it is at least in part due to decades of external actors violating Yemeni sovereignty with near impunity. The drone program, like the Saudi-led war, is merely a recent and overt example.

I lived in Yemen for several years spread over the period from 1994-1999. During that time, the optimism about the democratic opening of 1990 gave way to increasing frustrations as Salih solidified his control over united Yemen. He defeated the southern leadership in the 1994 war and curtailed the freedoms and pluralism that marked the early unification period, but open public debate has always been vibrant. Travel throughout Yemen was easy at that time, the only obstacle being the need to hire an all-terrain vehicle and driver who knew the many poorly marked roads.

The Yemenis I met cut across social classes and regions, but were overwhelmingly welcoming and friendly toward Americans. In my research on Islamist political parties in Yemen and Jordan, I talked to hundreds of self-described Islamists. I spoke to people in the larger cities, the smaller towns, and in rural areas. We spent long hours talking about Islam and debating the contemporary political problems facing Yemen, the United States, and the world. In 1995 we spoke extensively about race and class in America as Yemenis watched the O.J. Simpson trial on CNN International. I often marveled at the knowledge Yemenis had of the U.S. political system; I wondered if most Americans had comparable knowledge of any other country at all. I was welcomed into homes and shared holidays with families.

What strikes me now is how most Islamists saw jihadi groups as having no place in Yemeni politics. There were jihadis in Yemen, of course, primarily the “Afghan Arabs” who had returned from fighting abroad in Afghanistan and other theaters of jihad and faced difficulties reassimilating. Islamists donning mustaches complained about Taliban proclamations that adult male Muslims must sport a beard at least a fist long. They also complained of the Saudi-sponsored “scientific institutes” that taught the super-conservative Wahhabi take on Islam. Salih had even enjoined these extremists to launch deadly attacks against Southern socialists in the first years after unification. Most of the individuals influenced by these trends eventually found their way into al-Qaida circles.

But they were relatively few. Al-Qaida found little success in attracting Yemenis who were not already drawn to jihadi ideas. The al-Qaida recruiting pitch of attacking foreign powers inside of Yemen simply rang hollow. Even the 2000 attack upon USS Cole — a warship docked in Aden — was not widely viewed as the legitimate targeting of a foreign military power intervening in Yemeni politics. Al-Qaida had to resort to extremist tactics precisely because its ideas did not attract a following significant enough to spark a popular mobilization.

For al-Qaida, the drone program is a gift from the heavens. Its recruiting narrative exploits common misperceptions of American omnipotence, offering an alternative route to justice and empowerment. Regardless of American perceptions about the legitimacy or efficacy of the attacks, what Yemeni could now deny that the United States is waging an undeclared war on Yemen?

Most recently, this narrative of direct U.S. intervention has been further substantiated by U.S. material and intelligence support for the Saudi-led military campaign aimed at the return to power of the unpopular and exiled-President Abed Rabbo Mansour Hadi. Photographs of spent U.S.-made cluster bombs are widely circulated. Nor have drone attacks ceased; alongside the often indiscriminate Saudi-led bombing, American drones continue their campaign of targeted assassination. 

One might think that the Saudi attacks would not help al-Qaida, but it is contributing to al-Qaida’s growth in Yemen. The indiscriminate targeting of the Saudi-led campaign undermines any sense of security, let alone Yemeni sovereignty. And AQAP-controlled areas like the port of Mukalla are not being targeted by Saudi or Gulf troops at all. The United States aims to take up the job of targeting AQAP while the Saudi-led (and U.S.-backed) forces focus on defeating the Houthis and restoring Hadi to power. But the overall situation is one in which those multiple interventions in Yemen are creating an environment in which al-Qaida is beginning to appeal in ways it never had before.

For al-Qaida, the drone program is a gift from the heavens. Its recruiting narrative exploits common misperceptions of American omnipotence, offering an alternative route to justice and empowerment.

For these reasons, the U.S. use of drones to kill even carefully identified AQAP leaders in Yemen is counterproductive: it gives resonance to the claims of the very group it seeks to destroy. It provides evidence that al-Qaida’s claims and strategies are justified and that Yemenis cannot count on the state to protect them from threats foreign and domestic.

U.S. officials have argued that the drone program has not been used as a recruiting device for al-Qaida. But it is hard to ignore the evidence to the contrary, from counterinsurgency experts who have worked for the U.S. government to Yemeni voices like Farea Muslimi.

It’s not just that drone strikes make al-Qaida recruiting easier, true as that probably is, but that they broaden the social space in which al-Qaida can function. America does not need to win the “hearts and minds” of Yemenis in the service of some grand U.S. project in the region. But if America wants to weaken al-Qaida in Yemen, it needs at a minimum to stop pursuing policies that are bound to enrage and embitter Yemenis who might otherwise be neutral. 

There is an old saying that when the only tool you have is a hammer, everything starts to look like a nail. The U.S. military — let alone its drones — is not the only tool on which the United States can rely. But when the measure of success is as narrow as the killing of a specific person, the tool gets used with increasing frequency. Indeed, drone strikes have significantly expanded under the Obama administration.

It is crucial to see the bigger picture, the one in which long-time Yemeni friends tell me of growing anti-U.S. sentiment where there was previously very little. Public opinion toward America has clearly deteriorated over the past decade, and to reverse it may take much longer. But the use of drones to kill people deemed enemies of the United States, along with the Saudi-led war against the Houthis, is expanding the spaces in which al-Qaida is able to function.
