The United States has informed its European allies of plans to significantly scale back the military assets it allocates to NATO operations on the continent, a move that threatens to curtail the alliance’s long-range strike and surveillance capabilities at a moment of heightened strategic uncertainty. According to a written document circulated to partner nations in early June and reviewed by The New York Times, the proposed reductions are both specific and sweeping. Viewed from Washington, the recalibration is framed as a long-overdue correction compelling European members to assume greater responsibility for their own defence, a demand President Donald Trump has pressed with renewed vigour since his second inauguration in January 2025.

The blueprint envisages cutting the fleet of F-16 and F-15E fighter jets available to NATO from roughly 150 to 100 airframes, while maritime reconnaissance aircraft would be reduced from 26 to 15. All eight aerial refuelling tankers previously stationed in Europe are to be withdrawn entirely, a detail that defence analysts in London note would severely hamper the operational radius of any remaining allied combat aircraft. Beyond airpower, the Pentagon plans to redeploy a guided-missile submarine, an aircraft carrier and its accompanying strike group of warships and dozens of jets, effectively removing one of the two bomber task forces that had been earmarked for European defence. The US Eastern Command acknowledged it was “modifying” its force posture but declined to comment on specific figures.

European capitals have absorbed the notification with a mixture of alarm and grim vindication. Senior officials in Brussels and Stockholm described the proposed cuts as a potential “death blow” to the continent’s security architecture if fully implemented. The disclosure comes weeks after a leaked internal Pentagon email, reported by Reuters, even floated the option of suspending Spain from NATO over disagreements tied to the broader military campaign against Iran, underscoring the transactional tenor of Washington’s current alliance management. The timing is particularly delicate ahead of a NATO summit scheduled for July in Turkey, which Trump has confirmed he will attend, having previously excoriated European allies for refusing to join the war he and Israel launched against Tehran.

In response, NATO’s top military officer, Supreme Allied Commander Europe, is already weighing alternative defence plans that would rely less on American enablers, effectively drafting a Plan B for a continent that has depended on US military primacy for eight decades. The existing NATO Force Model, which governs the phased availability of member-state assets during a crisis, is being quietly re-examined to account for a future in which Washington’s focus is fixed elsewhere—potentially on contingencies in the Indo-Pacific or the Middle East. Thinkers at the Vienna-based GLOBSEC institute caution that the gradual reorientation of US forces is neither new nor unexpected, yet the specificity of the June document marks an inflection point.

What is emerging is not merely a logistical adjustment but a structural shift in the transatlantic bargain. The drawdown compels European NATO members to confront hard questions about strategic autonomy, industrial capacity, and nuclear deterrence architecture that have been deferred for decades. Whether this accelerates a genuine European defence integration or fractures alliance cohesion will depend heavily on the political will displayed in the months following the Turkish summit.
