The Pentagon has begun withdrawing American personnel from several NATO advisory groups, The Washington Post reported Tuesday, marking the United States' most concrete step toward strategic decoupling from the alliance it founded 75 years ago.
The move affects American participation in approximately a dozen NATO advisory bodies focused on military interoperability, joint procurement, and strategic planning. While the Pentagon emphasized these are "non-operational" groups that do not directly affect combat readiness, defense analysts described the withdrawals as a systematic dismantling of the institutional architecture that has underpinned transatlantic defense cooperation since 1949.
"This is death by a thousand cuts," said a senior European defense official speaking on condition of anonymity. "They're not leaving NATO tomorrow. They're making NATO irrelevant."
The Pentagon announcement comes as France requests NATO military exercises in Greenland to counter President Trump's territorial ambitions, Denmark deploys 1,000 combat troops to the Arctic territory, and the European Union suspends approval of a major US trade deal. Each development represents a separate thread of the unraveling transatlantic relationship, but the Pentagon move suggests Washington is methodically preparing for a post-NATO security posture.
The timing is not coincidental. The affected advisory groups include the NATO Air Defence Committee, the Army Armaments Group, the Naval Armaments Group, and several working groups on cyber defense and space operations. These bodies don't command troops or make policy, but they serve a critical function: ensuring that American, European, and Canadian forces can operate together seamlessly in a crisis.
Without American participation, European militaries will face growing challenges maintaining interoperability with US systems. Everything from communications protocols to ammunition calibers to air traffic control procedures relies on standardization work done in these advisory groups. Their degradation won't cause immediate operational failures, but it will gradually make combined operations more difficult and less effective.
