The Signal scandal drew howls of outrage for the way Trump administration officials insecurely exchanged texts about military strikes on Yemen. But dig a little deeper, and there’s an even larger scandal.

This is a scandal about a failed policy that empowers an enemy of the United States, weakens our security and will cost thousands of lives. It’s one that also tarnishes President Joe Biden but reaches its apotheosis under President Trump.

It all goes back to the brutal Hamas terrorist attack on Israel in October 2023, and Israel’s savage response leveling entire neighborhoods of Gaza. The repressive Houthi regime of Yemen sought to win regional support by attacking supposedly pro-Israeli ships passing nearby in the Red Sea. (In fact, it struck all kinds of ships.)

There are more problems than solutions in international relations, and this was a classic example: An extremist regime in Yemen was impeding international trade, and there wasn’t an easy fix. Biden responded with a year of airstrikes on Yemen against the Houthis that consumed billions of dollars but didn’t accomplish anything obvious.

After taking office, Trump ramped up pressure on Yemen. He slashed humanitarian aid worldwide, with Yemen particularly hard hit. I last visited Yemen in 2018, when some children were already starving to death, and now it’s worse: Half of Yemen’s children under 5 are malnourished — “a statistic that is almost unparalleled across the world,” UNICEF says — yet aid cuts recently forced more than 2,000 nutrition programs to close down, according to Tom Fletcher, the U.N. humanitarian chief. The United States canceled an order for lifesaving peanut paste that was meant to keep 500,000 Yemeni children alive.

Girls will be particularly likely to die, because Yemeni culture favors boys. I once interviewed a girl, Nujood Ali, who was married against her will at age 10. Aid programs to empower Yemeni girls and reduce child marriage are now being cut off as well.
