Experts react: What to know about US and UK strikes on the Houthis in Yemen
Consequences were promised . . . and delivered. Last month, the United States formed a coalition of more than twenty nations called Operation Prosperity Guardian to respond to Houthi attacks on ships in the Red Sea. Last week, the United States, along with allies and partners, issued a stark warning to the Houthis to stop their aggression or face repercussions. Then, following another attack on shipping lanes on Tuesday, US and UK forces launched air and missile strikes on Thursday against dozens of Houthi targets in Yemen.
Below, Atlantic Council experts share their views on what to know about the strikes and what to expect next—including the prospects of a regional war with Houthi-backer Iran.

The lessons Washington needs to learn from the strike
US President Joe Biden should be applauded for Thursday’s strikes against the Houthis. International trade is constrained by eight primary maritime chokepoints, hard realities imposed by immutable geography. The United States has long recognized a vital national security interest in ensuring freedom of navigation through each of them. This strike helped protect those interests.
Half of these eight global chokepoints are dispersed widely. Only one each can be found in Europe (the Strait of Gibraltar), in Africa (the Cape of Good Hope), in East Asia (the Straits of Malacca), and in the Americas (the Panama Canal). Unfortunately, the other half of these critical chokepoints are all concentrated in a relatively small region where southwestern Asia meets Europe and Africa: the Bosporus Strait, the Suez Canal, the Bab-el-Mandeb Strait, and the Strait of Hormuz. This area also happens to be the most important single source of the energy required to sustain global economic growth. Those two facts explain why US presidents keep rediscovering the need to focus disproportionately on the Middle East, despite their often-heartfelt desires to do otherwise.
Today, the greatest threat to these chokepoints is Iran and its proxies. The regime in Tehran has long threatened to shut down Hormuz and repeatedly attacked shipping in the area. Most recently, it even threatened to shut down Gibraltar. The Houthis, Iran’s partner and proxy in Yemen, had repeatedly attacked ships transiting the Bab. The Biden administration recognized the threat, laid the diplomatic predicate, assembled the multilateral coalition, deployed the assets, issued clear warnings, and then took action. This is what professional policymaking looks like. One hopes that the right lessons will be learned in both Sanaa and Tehran.
But the United States also needs to learn its own lessons. Across multiple administrations and congressional terms, Washington has long underestimated the inherent threat posed by the Houthis, and thus allowed the conditions to develop that allowed the Houthis to prosper. Thursday’s action should mark the end of those practices.

Are the US and its allies willing to conduct additional strikes?
Today’s strikes against the Houthis are not the first time the United States has been involved in responding to the military group. The 2016 US strikes against the Houthis have likely been lost in the noise of thousands of Saudi-led coalition strikes against the group. What these strikes demonstrated is that the Houthis have long been willing to accept military and civilian casualties from airstrikes against the group. Far from being deterred, the Houthis instead invested their resources, and those provided by Iran, into increasingly capable weapons systems. Due to the group’s experience in withstanding years of airstrikes, today’s strikes are unlikely to achieve strategic deterrence—meaning the Houthis will continue to desire to target Red Sea shipping.
However, today’s strikes are focused on something more achievable. It appears that the US and UK strikes went after the Houthis command-and-control, maritime-domain awareness, and attack capabilities. The need to deprive the Houthis of the means of conducting additional attacks against US, coalition, and commercial maritime traffic is a matter of public record through countless White House and Department of Defense statements. Additionally, this focused response against the Houthis makes escalation less likely as the targets can be considered legitimate military targets.
The challenge, of course, will be the degree to which the United States, the United Kingdom, and the coalition are willing to conduct additional strikes in the likely event that the Houthis continue to attack shipping. The success of additional rounds of strikes against the Houthis may then depend on the US and coalition’s ability to interdict Iranian resupply to the Houthis. The need to consider disruption options against Iran’s malign activity across the region will likely rise as a future consideration.

From Iran to Saudi Arabia, the strikes will cause regional reverberations
The decision by the United States and allies to strike Houthi assets on January 11 was necessary and right. The Houthis had conducted more than two dozen attacks in the last seven weeks, disrupting global maritime traffic and threatening allies. But the US and UK strikes are unlikely to halt Houthi aggression in the Red Sea.
For the United States and the coalition, the goal is to restore deterrence. That will almost certainly mean having to continue to respond to Houthi strikes, and potentially with increasing aggression in order to have a meaningful impact on Houthi leadership thinking. It will not be easy. The Houthis view themselves as having little to lose, emboldened militarily by Iranian provisions of support and confident that the United States will not entertain a ground war. That may be true. But the United States can still have a meaningful impact on reducing both the capabilities and effectiveness of the Houthis. Moreover, in undertaking such a strategy, Washington will also send a meaningful message to other Iranian proxies about US willingness to use force in the region to protect not only itself but its allies and partners, as well. For Iran, the Houthis are probably the least important proxy they have and, in turn, also probably a good test case of US and allied reactions.
Saudi Arabia, which has been continuing negotiations with the Houthis to permanently end their conflict, is likely to have mixed views of the strike. On one hand, Riyadh is certain to be concerned that the Houthis will end negotiations and retaliate directly by attacking Saudi soil. But on the other, it’s likely to recognize that its negotiations with the Houthis will be more challenging the greater leverage the Houthis gain—and the ability of the group to operate in the region with impunity certainly increases its leverage. Moreover, the cold detente it has found with Iran is unlikely to be sustainable if the regional balance of power tilts so much that Tehran’s terrorist partners and proxies can operate throughout the region with only minimal reactions by the United States or its allies. That may be short-term peace for Saudi Arabia, but will not buy long-term security.
Washington’s decision to respond today is an unfortunate necessity. It’s true that such action increases the risk of regional escalation. But, if Iran and its proxies view themselves as free to exert terrorist and malign influence throughout the region without fear of retribution, then the risk of regional conflict—and a longer and deadlier one—would be even more likely in the coming months and years. Today may mark the coalition’s first strike against the Houthis, but it is unlikely to be the last. Nor should it be. Creating last deterrence requires a sustained effort.

A US-led military response was inevitable. Whether this escalates is up to the Houthis.
No one should be surprised at the US and UK strikes on Houthi drone and missile sites and military bases today. Repeated, direct warnings that the Houthis should stop their attacks on merchant shipping in the Red Sea made clear that further attacks would produce a military response. The barrage of Houthi missile and other strikes on January 9 in the Red Sea made a military response inevitable.
The initiative now passes to the Houthis to see if they want to continue their war against the world. The challenge has long been that Iran, which provides technology and crucial parts for the Houthis’ missiles and drones, will continue to urge its proxy to carry out attacks regardless of US strikes. Iran is not deterred by attacks on its proxies. But it remains to be seen what it will take to deter the Houthis from continuing to be involved in Iran’s proxy war against the United States and its allies. The world is about to find out whether the Houthis want to continue their attacks—and risk the United States and its allies striking even more of the group’s strategic targets.

Iran’s proxies are only a symptom of a larger disease
On Thursday night, an international military coalition including the United States conducted air and missile strikes against targets in western Yemen, an area under the control of Ansar Allah, commonly referred to as the Houthi rebels. The purpose of the strikes was to disrupt and degrade the Houthis’ military capabilities after they launched ballistic missiles at Israel, attacked naval ships and commercial vessels off of Yemen’s coast, and effectively shut down international shipping lanes by making them unsafe. The strikes followed several public and diplomatic warnings from the coalition that Ansar Allah willfully ignored.
The strikes come less than a year after a China-brokered rapprochement between Iran and Saudi Arabia. Tehran and Riyadh had been fighting a proxy war in Yemen, with Saudi Arabia leading a coalition to defend the government of Yemen and Iran supporting the Shia Ansar Allah rebels. More than 350,000 people are estimated to have died in the ten-year-long conflict. Yemen remains divided at this time between an Ansar Allah-controlled west and a Yemeni government-controlled east.
Ansar Allah was previously designated by the United States as a foreign terrorist organization, but the designation was removed by the Biden administration several years ago. The controversial move followed a cooling of relations between Riyadh and Washington and a push to end the war and revive the Iran nuclear deal.
Ansar Allah is part of what has been labeled the “axis of resistance,” an unofficial coalition of Iran-backed terrorist and insurgent groups throughout the Middle East that have conducted attacks against Israel, US troops, and other allied nations’ military forces in the region. The “axis” includes Hamas in Gaza, Hezbollah in Lebanon, Shia militias in Iraq and Syria, and the Ansar Allah in Yemen.
Iran supports these groups with the intent to maintain plausible deniability while having them act as proxies, conducting attacks against Western targets in the region and Israel. Iran will not feel the pain associated with the strikes in Yemen and is unlikely to be deterred.
These strikes were necessary to disrupt and degrade Ansar Allah’s military capabilities to strike Israel and disrupt commercial shipping. Additional actions should be taken to restore deterrence with Iran. Only dealing with the proxies is akin to only addressing the symptoms, as opposed to the underlying disease.
