A group chat by high-ranking U.S. officials discussing military operations in Yemen accidentally included a journalist, causing alarm among allies. European diplomats criticized the incident as reckless, highlighting concerns over U.S. security protocols and intelligence-sharing reliability. U.S. officials expressed disdain for European allies, exacerbating tensions already strained by President Trump's 'America First' policies. In public, European leaders maintained support for collaboration with the U.S., but potential impacts on intelligence sharing were acknowledged. The breach prompts calls for reassessing the reliability of the trans-Atlantic partnership and highlights Europe's military independence amidst shifting dynamics.
