Yesterday, Americans commemorated the 2001 terrorist attacks on New York City and Washington. In the years before those attacks, the U.S. took little note of the 1993 World Trade Center bombing, or al-Qaeda’s murderous assaults on the USS Cole and on the American embassies in Tanzania and Nairobi. H.R. McMaster and Bradley Bowman argue that Washington remains in the grip of a “bipartisan habit of self-delusion” about the dangers of al-Qaeda, which has recently restored its base of operations in Taliban-ruled Afghanistan:

The Taliban gave al-Qaeda a safe haven to plan 9/11, and the two groups have remained attached at the hip ever since. Indeed, no less than a United Nations monitoring team reiterated in an April 2021 assessment that “the Taliban and al-Qaeda remain closely aligned and show no indication of breaking ties.” You know there is a problem when a UN entity has a clearer view of the United States’ enemies than the White House.

The Biden administration failed to learn from the last complete withdrawal: from Iraq in 2011 and the subsequent reemergence of al-Qaeda there, soon to morph into Islamic State. By the summer of 2014, Islamic State had gained control of territory in Iraq and adjoining Syria roughly the size of Britain and became one of the most destructive and powerful terrorist organizations in history. It turns out that threats don’t subside when one simply ignores realities on the ground, decides to stop fighting, and returns home. In fact, they usually get worse.

The United States and its partners in the region have now deprived Islamic State of its so-called caliphate in Iraq and Syria because a small number of U.S. troops were kept there to support others bearing the brunt of the fighting. The Taliban-al-Qaeda terror syndicate now has an emirate because the United States failed to do the same in Afghanistan.

So why does this all matter today? If the United States fails to keep pressure on terrorist groups like al-Qaeda, it should expect more attacks on its homeland. But more than that, if Americans don’t demand an end to self-delusion in Washington regarding the nature and objectives of the country’s adversaries and what is necessary to secure its national interests, they should expect more self-defeat when confronting other adversaries—such as Beijing, Moscow, Pyongyang, and Tehran.

Last Tuesday, the Houthis—the faction now ruling much of Yemen—said that they intend to renew attacks on international shipping through the Red and Arabian Seas. They had for the most part paused their attacks following the January 19 Israel-Hamas cease-fire, but their presence has continued to scare away maritime traffic near the Yemeni coast, with terrible consequences for the global economy.

The U.S. responded on Saturday by initiating strikes on Houthi missile depots, command-and-control centers, and propaganda outlets, and has promised that the attacks will continue for days, if not weeks. The Houthis responded by launching drones, and possibly missiles, at American naval ships, apparently without result. Another missile fired from Yemen struck the Sinai, but was likely aimed at Israel. As Ari Heistein has written in Mosaic, it may take a sustained and concerted effort to stop the Houthis, who have high tolerance for casualties—but this is a start. Ron Ben-Yishai provides some context:

The goal is to punish the Houthis for directly targeting Western naval vessels in the Red Sea while also exerting indirect pressure on Tehran over its nuclear program. . . . While the Biden administration did conduct airstrikes against the Houthis, it refrained from a proactive military campaign, fearing a wider regional war. However, following the collapse of Iran’s axis—including Hizballah’s heavy losses in Lebanon and the fall of the Assad regime in Syria—the Trump administration appears unafraid of such an escalation.

Iran, the thinking goes, will also get the message that the U.S. isn’t afraid to use force, or risk the consequences of retaliation—and will keep this in mind as it considers negotiations over its nuclear program. Tamir Hayman adds:

The Houthis are the last proxy of the Shiite axis that have neither reassessed their actions nor restrained their weapons. Throughout the campaign against the Yemenite terrorist organization, the U.S.-led coalition has made operational mistakes: Houthi regime infrastructure was not targeted; the organization’s leaders were not eliminated; no sustained operational continuity was maintained—only actions to remove immediate threats; no ground operations took place, not even special-forces missions; and Iran has not paid a price for its proxy’s actions.

But if this does not stop the Houthis, it will project weakness—not just toward Hamas but primarily toward Iran—and Trump’s power diplomacy will be seen as hollow. The true test is one of output, not input. The only question that matters is not how many strikes the U.S. carries out, but whether the Red Sea reopens to all vessels. We will wait and see—for now, things look brighter than they did before.
