Signal chat blunder shows pitfalls of Trump’s ad hoc approach to foreign policy

Subscribe to enjoy similar stories. Texts by President Trump’s advisers about whether to attack Houthi militants in Yemen underscored the ad hoc nature of the administration’s national security deliberations, a mode that has sometimes left allies bewildered and his own aides at odds. Other presidents have relied on the State Department, Pentagon and National Security Council staff to develop and filter options in an orderly manner.

The Trump team has operated in a far less orthodox fashion, one that stems from the president’s impatience with debate and skepticism of bureaucracy. Many of his top advisers, few of whom have held senior positions before, share that perspective. That has proved a hindrance at times for Trump, who entered office this year promising a swift end to the war between Ukraine and Russia, peace in Gaza, a quick halt to Iran’s nuclear program, the acquisition of foreign territory, and an economic boom delivered by tariffs.

When national security adviser Mike Waltz created the “Houthi PC small group" on Signal earlier this month, it appeared meant for routine updates to Trump administration officials involved in deliberations on whether to strike Houthi militants. It quickly evolved into something more serious—a chat group on a nongovernment app where over the next two days Waltz and other members of the national security team debated by text whether to launch the attack. The exchanges became public after Atlantic Editor-in-Chief Jeffrey Goldberg was inadvertently added to the group.

Trump insists the Signal chats didn’t derail U.S. strikes on the Houthis. “The attack was totally successful," he told reporters Tuesday, defending Waltz and his team for overseeing the military operation.
