China Tests the Limits of Impunity
The Trump administration’s top goal in the Middle East is clear: counter Iran, which U.S. President Donald Trump and his senior officials have denounced as a duplicitous and murderous state sponsor of terrorism and sower of regional chaos. In May, the Trump administration invoked Tehran’s regional ambitions to justify U.S. withdrawal from the 2015 Iran nuclear deal. Just this week, Secretary of State Mike Pompeo warned that Iran’s regime was bent upon “the export of Islamic revolution and the destruction of its neighbors.”
Yet such warnings of the Iranian threat miss a key factor: the United States’ own policies have at times advanced rather than hindered Tehran’s regional ambitions. Nowhere is this clearer than in Yemen. U.S. support for a brutal Saudi-led military campaign in the country has created a humanitarian crisis of staggering proportions, while offering an opening for Iran to expand its influence in the country. Military intervention has made insurgents more reliant on support from Tehran and is turning civilians against U.S. partners. If Washington wants to counter Iranian influence, it needs to reverse course—ending its disastrous support for the Saudi-led coalition and throwing its weight behind peace talks. Doubling down on the military effort will serve only to further Iran’s regional ascendance.
The roots of the current conflict in Yemen trace back to the early 2000s, when Houthi rebels from the northern region of Saada repeatedly rebelled against the regime of then resident Ali Abdullah Saleh, hoping to increase their share of state patronage. Arab Spring protests in 2011 forced Saleh to step down and hand power to his second-in-command, Abd Rabbu Mansour Hadi. Behind the scenes, however, Saleh schemed with loyal military forces to retain his influence. Taking advantage of the ensuing chaos, Houthi rebels conquered the capital, Sanaa, in 2014. By the following year, they controlled much of Yemen. Fighting against the Houthis—and among each other—were supporters of Hadi’s government, a local al Qaeda branch, southern separatists, and a collective of local actors.
Blithely ignoring this complexity, Saudi Arabia and the United Arab Emirates entered the war in March 2015, seeking to put Hadi back in power and fight the Houthis, whom they saw as a proxy of their archenemy, Iran. Saudi and Emirati leaders feared that, through the Houthis, Iran would gain a foothold in Yemen much as it had done in Lebanon, where Tehran has a powerful proto-state ally in the form of Hezbollah. Saudi leaders predicted that the intervention would quickly tip the scales and that the civil war would end after only a few weeks.
Three years later, what was supposed to be a short, decisive intervention has ground on, with no end in sight. The campaign has reclaimed parts of southern Yemen from the Houthis. But the insurgents have kept control over the capital, Sanaa, and still boast tens of thousands of armed fighters.
There has been good reason for policymakers in Saudi Arabia, the UAE, and Washington to worry about Iranian ascendance across the region. Tehran’s closest ally, Syrian dictator Bashar al-Assad, has made steady headway against insurgent groups, including forces backed by the United States and its allies. In May, elections in Iraq and Lebanon boosted the influence of Iranian-backed groups, while the United States’ and the Saudis’ favored candidates suffered setbacks. An Iranian member of parliament has famously boasted that his country controls “four Arab capitals”—Baghdad, Beirut, Damascus, and now Sanaa.
Yet it’s easy to overstate Iran’s hold on the region overall—and on Yemen in particular. In reality, the Houthis and Iran are allies of convenience against the U.S.-backed Saudi military campaign. Although the Houthis are commonly referred to as Shiites, their faith more closely resembles Sunnism than Shiism as practiced in Iran. Unlike the Lebanese Hezbollah, they do not profess loyalty to Iran’s Supreme Leader. The Persian-Arab divide, the Houthis’ focus on accessing state patronage in Yemen, and a strong sense of Yemeni independence also complicate the idea that the Houthis are Tehran’s proxies.
But because of the Saudi-led campaign meant to push back on Iran, Tehran now has an opening in Yemen it might otherwise not have had. Iran gives the Houthis arms, including short-range ballistic missiles, and in exchange the Houthis have offered it an entry into a part of the world where its influence had once been limited. Houthis have threatened ships off the Yemeni coast with Iranian missiles, even hitting a Turkish ship delivering humanitarian aid. And their slogans, speeches, and media strategy increasingly echo those of Hezbollah, lending some support to Saudi fears that the group may be turning into a Yemeni version of Iran’s Lebanese proxy. In addition, Shiites in other countries are embracing the Houthi cause as part of what they see as a larger struggle against Sunni hegemony.
Because of the Saudi-led campaign meant to push back on Iran, Tehran now has an opening in Yemen it might otherwise not have had.
The UAE has deployed significant ground forces, while Riyadh has flown over 100,000 sorties and spends $5 billion to $6 billion a month on the war—far more than Tehran spends on support for the Houthis. The war has killed around 10,000 people, and a Saudi blockade of Yemeni ports has exacted a bitter humanitarian toll. Last year, Yemen suffered the world’s largest cholera outbreak. Starvation and disease have killed more than 50,000 children, and hundreds of thousands more are malnourished. The blockade has been loosened, but the damage it brought has turned many Yemenis, long distrustful of their Saudi neighbor, even more hostile. It has also hurt Saudi Arabia’s image in Europe and other parts of the world that care about the suffering of the Yemeni people.
Even as Yemen implodes, U.S. allies sink into the quagmire, and Iran’s influence grows as a result, the United States has provided tacit support for the Saudi-led military campaign. Under Barack Obama, U.S. policy in Yemen was often confused, struggling to balance humanitarian concerns with a desire not to alienate U.S. allies. When Saudi Arabia and the United Arab Emirates launched their intervention in 2015, the Obama administration neither wholeheartedly embraced nor strongly opposed it, eventually settling into lukewarm acceptance. Quietly, the United States—along with France and the United Kingdom—provided intelligence and air refueling along with other logistical support. Before leaving office, Obama gave the Saudis a symbolic wrist slap, halting the sale of smart bombs to the kingdom because of the war. This proved to be the worst of both worlds, angering allies while doing nothing to stop the intervention or improve the situation in Yemen.
Trump quickly lifted Obama’s smart bomb ban, but his administration has not veered dramatically from Obama’s policy of cautious and grudging support, especially after a botched special operations forces raid in Yemen led to the death of a U.S. Navy SEAL and perhaps over 20 civilians in early 2017. In June, the United States rebuffed a request to join the UAE-led offensive on Hodeidah, a crucial port through which food and other supplies go into Houthi-held areas. Still, the International Crisis Group has described the U.S. State Department’s messaging on the offensive as a subdued “yellow light” that allies can confidently ignore. More broadly, the Saudis and the UAE feel empowered by the strong embrace the Trump administration has given them up to this point and see no need to change course in Yemen.
Washington should end its casual support for its allies’ ill-fated and destructive efforts. Doing so is in its own strategic interest: Iran is stronger in Yemen than it was at the outset of the Saudi-led intervention. The United Arab Emirates and Saudi Arabia have spent tens of billions on the war, and many Yemeni hate them for the destruction they have brought. Even with a Houthi defeat in Hodeidah, the war will likely drag on.
Moreover, the United States’ yellow light does not absolve it from its complicity in the humanitarian disaster gripping Yemen. Although the Trump administration has done little to suggest that it cares about humanitarian crises, especially in the Middle East, its logistical and intelligence support for the intervention ties it directly to the Yemenis’ suffering. This is true even though leaders claim that the United States is not at war and few U.S. citizens know of their country’s role in the conflict. As Senator Mike Lee (R-Utah) has noted, “It stretches the imagination, and it stretches the English language beyond its breaking point, to suggest the U.S. military is not engaged in hostilities in Yemen.”
Ironically, Trump may need the goodwill of the Saudis and Emiratis much less than his predecessor did. Both allies support the U.S.-led coalition against ISIS, but the campaign’s success has largely driven the caliphate underground in Iraq and Syria. Notionally, the Saudis and the United Arab Emirates also play a role in Trump’s Arab-Israeli peace plans, but given that these are deeply unrealistic and unformed, this is of little relevance. Even within Yemen, the United States has tremendous leverage over its allies—it just won’t use it. As researcher and aid expert Alex De Waal argues, the in-flight refueling, presence of U.S. advisers, and arms sales all offer tools for the United States to exert pressure on its allies.
Although the Trump administration is unlikely to seize it, the UAE’s current assault on the strategic, Houthi-held port of Hodeidah offers an opportunity to renew negotiations. The United States should support the ongoing efforts of Martin Griffiths, the UN’s new envoy to Yemen, to halt the offensive and conduct peace talks. Congress could encourage such efforts, using its influence over the approval of arms sales and control over U.S. military spending to push the administration. Hearings on growing Iranian influence and the humanitarian crisis in Yemen that involve public criticism of publicity-sensitive allies such as Saudi Arabia also can shift the debate. An attack on Hodeidah by the Saudi-UAE coalition forces is likely to be costly to both sides, but a defeat would be particularly devastating for the Houthis, who would lose a supply port as well as a visible symbol of their military might. To prevent such an outcome, the Houthis could be encouraged to enter a deal on the condition of reducing ties to Tehran. In the absence of such a deal, however, they are likely to double down on Iran’s support, which would become their primary lifeline. U.S. allies, for their part, can claim victory in Hodeidah and enter negotiations with a “win,” allowing them to at least reduce the scale of their interventions. That won’t solve Yemen’s problems or fully remedy the problem of Iran’s growing regional power, but it would be a step in the right direction.
