Heather Cox Richardson has the gift of synthesis, which is the mark of a good historian. Very likely, we all saw the headlines about missile attacks on Houthi bases in Yemen. In all probability, few of us had ever heard of this group before October 2023. They are doing Iran’s dirty work. Her piece also cites Politico, which reported that in 2020 Trump warned the president of the EU that if Europe was invaded, the U.S. would not come to its aid and that NATO was dead.

She explains:

“Today, at my direction,” President Joe Biden said this evening, “U.S. military forces—together with the United Kingdom and with support from Australia, Bahrain, Canada, and the Netherlands—successfully conducted strikes against a number of targets in Yemen used by Houthi rebels to endanger freedom of navigation in one of the world’s most vital waterways.”

The strikes came after the Iran-backed Houthi militia launched 27 attacks on vessels in the Red Sea, including merchant shipping vessels that carry about 12% of the world’s oil, 8% of its grain, and 8% of liquefied natural gas, as well as other commodities.

While the Houthis claim their attacks are designed to support the Palestinians in Gaza, they are also apparently angling to continue and spread the Hamas-Israel war into a wider conflict. Hamas, the Houthis, and Hezbollah, all nonstate actors backed by Iran, would like very much to extend and enlarge the war to enhance their own power and win adherents to their ideologies.

The Arab states do not want the conflict to spread. Neither does the U.S. government, and Biden and Secretary of State Antony Blinken have worked hard to make sure it doesn’t, sending two carrier groups to the region, for example, to deter enthusiasm for such an extension.

On October 19, shortly after the October 7 Hamas attack on Israel, Houthis launched cruise missiles and drones designed by Iran at Israel, but when the USS Carney and Saudi Arabia shot the weapons down, they turned to attacking shipping. Fifty or so ships use the Red Sea waterway every day.

On November 19, Houthis seized a Japanese-registered vessel, the Galaxy Leader, along with its 25-member international crew, prompting the United Nations Security Council to condemn “in the strongest terms” the “recent Houthi attacks” and “demanded that all such attacks and action cease immediately.” The Security Council “underlined the importance of…international law.”

On December 3, Houthis struck another three ships.

On December 19, the U.S., the European Union, the North Atlantic Treaty Organization, and a group representing 44 allies and partner nations condemned the Houthi attacks, noting that such attacks threatened international commerce, endangering supply chains and affecting the global economy. Also on December 19, the U.S. and partners announced a naval protection group for maritime shipping in the waterway, dubbed Operation Prosperity Guardian.

When the attacks continued, the governments of the U.S., Australia, Bahrain, Belgium, Canada, Denmark, Germany, Italy, Japan, Netherlands, New Zealand, Republic of Korea, Singapore, and the United Kingdom warned the Houthis on January 3, 2024, that their attacks were “illegal, unacceptable, and profoundly destabilizing,” delaying the delivery of goods and “jeopardizing the movement of critical food, fuel, and humanitarian assistance throughout the world.” They called for an end to the attacks and the release of the detained vessels and crew members, and they warned that the Houthis would bear responsibility for the “consequences” if the attacks continued.

“We remain committed to the international rules-based order and are determined to hold malign actors accountable for unlawful seizures and attacks,” the statement said.

Administration officials told the press the U.S. would strike the Houthis militarily if the attacks didn’t stop, although Biden has not wanted to destabilize Yemen further than it already is after a decade of civil war. “The president has made clear the U.S. does not seek conflict with any nation or actor in the Middle East,” John Kirby, spokesperson for the White House National Security Council, said. “But neither will we shrink from the task of defending ourselves, our interests, our partners or the free flow of international commerce.” An administration official said: “I would not anticipate another warning.”

On Tuesday, January 9, the Houthis launched 21 drones and missiles in the most significant attack yet—one that directly targeted U.S. ships—and on January 10 the U.N. Security Council passed UNSCR 2722, a resolution condemning the attacks “in the strongest terms.” Eleven members voted in favor and none opposed it. Four countries—China, Russia, Algeria, and Mozambique—abstained, but neither China nor Russia, both of which have veto power, would veto the resolution.

Today the U.S. and the U.K., with coalition support, responded. Military strikes came from the air, ocean, and underwater, according to a defense official, and they hit weapons storage areas and sites from which the Houthis have been launching drones and cruise missiles.

The governments of Australia, Bahrain, Canada, Denmark, Germany, Netherlands, New Zealand, Republic of Korea, the U.K, and the U.S. announced the “precision strikes,” saying they were “in accordance with the inherent right of individual and collective self-defense, consistent with the UN Charter” and “were intended to disrupt and degrade the capabilities the Houthis use to threaten global trade and the lives of international mariners in one of the world’s most critical waterways.”

“Our aim remains to de-escalate tensions and restore stability in the Red Sea,” the statement read, “but let our message be clear: we will not hesitate to defend lives and protect the free flow of commerce in one of the world’s most critical waterways in the face of continued threats.” Biden’s statement sounded much the same but added: “I will not hesitate to direct further measures to protect our people and the free flow of international commerce as necessary.”

As the January 3 statement from the governments of the U.S., Australia, Bahrain, Belgium, Canada, Denmark, Germany, Italy, Japan, Netherlands, New Zealand, Republic of Korea, Singapore, and the U.K. made clear, one of the key things at stake in standing against the Houthi attacks is the international rules-based order, that is, the system of international laws and organizations developed after World War II to prevent global conflicts by providing forums to resolve differences peacefully. A key element of this international system of agreements is freedom of the seas.

Also central to that rules-based international order is partnerships and allies. Two days ago, one of Europe’s leading politicians revealed that in 2020, former president Trump told European Commission president Ursula von der Leyen: “You need to understand that if Europe is under attack, we will never come to help you and to support you.” According to the politician, Trump added that “NATO is dead, and we will leave, we will quit NATO,” a threat he has made elsewhere, too.

In contrast, as soon as he took office, President Biden set out to support and extend U.S. alliances and partnerships. While that principle shows in the international support for today’s strike on the Houthis, it has also been central in the administration’s response to Russia’s 2022 invasion of Ukraine, managing migration, supporting African development, building the Indo-Pacific, and reacting to the Middle East crisis in general.

Today, Secretary of State Blinken finished a week-long trip to Türkiye, Greece, Jordan, Qatar, the United Arab Emirates, Saudi Arabia, Israel, the West Bank, Bahrain, and Egypt, where he met with leaders and reaffirmed “the U.S. commitment to working with partners to set the conditions necessary for peace in the Middle East, which includes comprehensive, tangible steps toward the realization of a future Palestinian state alongside the State of Israel, with both living in peace and security.”
