A bombshell security breach has left America’s allies reeling after senior Trump administration officials accidentally included The Atlantic editor Jeffrey Goldberg in a Signal group chat plotting strikes on Yemen’s Houthi rebels.

The blunder, exposing operational details hours before the March 15 attack, has sparked outrage and doubts about intelligence-sharing with Washington, with European leaders and experts branding it “reckless” and “scary.”

The chat—featuring Vice President JD Vance, Defense Secretary Pete Hegseth, and others—didn’t just reveal war plans; it laid bare disdain for allies. Vance griped about “bailing out” Europe, while Hegseth slammed “pathetic European freeloaders,” amplifying strains from Trump’s “America First” ethos.

Security analyst Neil Melvin of the Royal United Services Institute called it “pretty shocking,” pointing to a “disregard for protocols” among top U.S. brass.

Publicly, allies downplayed the rift. UK Prime Minister Keir Starmer’s spokesman, Dave Pares, insisted the U.S. remains Britain’s “closest ally” on security, a stance echoed by France’s foreign ministry.

Yet, privately, a European diplomat, speaking anonymously, warned the lapse could erode trust in joint ops, hoping it’s inexperience, not intent. Canada’s Mark Carney stressed learning from the “serious issue,” while MEP Nathalie Loiseau quipped to the BBC that Putin’s spies are redundant—“the U.S. leaks itself.”

The Five Eyes alliance, especially Britain—whose RAF refueled U.S. jets during the strike—faces scrutiny. UK Minister Luke Pollard vouched for intact safeguards, but Liberal Democrat leader Ed Davey warned that Trump’s team can’t secure its own secrets, risking British lives if shared intelligence spills.
