Who’s the Real Criminal at Sea? Trump’s Tanker Grab vs. the Houthis’ Anti-Genocide Blockade

The United States has now intercepted multiple Venezuelan oil tankers as part of its escalating aggression against Venezuela, while also destroying dozens of small boats in the Caribbean and Pacific under the banner of “drug enforcement,” killing over 100 people whose identities the U.S. has obscured. At the same time, the Trump administration has threatened a naval blockade of Venezuela—a sovereign country with which the United States is not at war.

How can Washington claim the right to seize or blow up vessels, disrupt maritime trade, and kill civilian boaters—while bombing Yemen and condemning its de facto Houthi government for intercepting ships in the Red Sea to counter Israel’s genocide in Gaza?

This contrast exposes a stark double standard in U.S. policy. The U.S. government labelled the Houthis’ actions as “terrorism”, piracy, and a threat to U.S. national security, even as the Houthi government presented plausible legal justifications for its actions based on the laws of war. But Washington has tried to normalize—or even glorify—its own attacks on tankers, pineros (ferries or water-taxis) and fishing boats, which violate the most basic principles of international law.

Beginning in November 2023, Yemen’s Houthi movement launched a naval campaign in the Red Sea, Gulf of Aden, and Arabian Sea in response to Israel’s assault on Gaza. The Houthis publicly announced their criteria, stating they would target only vessels linked to Israel, bound for Israeli ports, owned by Israeli companies, or connected to states materially supporting Israel’s war.

The United States and its allies immediately denounced these actions as criminal. And there were legitimate grounds for scrutiny. Human rights groups raised concerns about attacks that struck vessels without obvious Israeli connections and about the safety and treatment of civilian crews. Over the course of the campaign, the Houthis targeted more than 100 commercial vessels, damaged dozens, sank several, and seized at least one ship outright—the Galaxy Leader—detaining its multinational crew for more than a year before releasing them in connection with Gaza ceasefire negotiations.

Legal experts have been unequivocal: the United States has no jurisdiction to seize foreign-flagged vessels to enforce its domestic laws or unilateral sanctions outside its territory, particularly in another country’s territorial waters.

But as a matter of law, the Houthis consistently framed their actions as blockade and interdiction during an armed conflict, justified by Israel’s grave breaches of international humanitarian law. That legal framework exists. Under the Geneva Conventions and customary international law, parties to an armed conflict have the right—and in cases of grave breaches, the obligation—to interdict shipping that materially supports a belligerent committing mass civilian harm. In the case of Israel’s genocide, the International Court of Justice (ICJ) has found, and the UN General Assembly (UNGA) has
