• The Trump administration plans to inform NATO allies this week that the U.S. will reduce the pool of forces and personnel it makes available for major crises.
  • The move is framed as an effort to push Europe to take greater responsibility for its own defense, but allies worry it signals a broader U.S. pullback from the alliance.
  • The Pentagon is expected to outline the plan at a NATO meeting in Brussels on Friday, following reports of cuts to U.S. command positions.

A Shift in U.S. Commitment

The Trump administration is set to announce a significant reduction in U.S. military commitments to NATO, a decision that underscores President Trump's longstanding push for Europe to shoulder more of the defense burden. According to people familiar with the matter, Washington will shrink the number of U.S. forces it designates for NATO's response during major crises and cut American billets from key command structures and advisory groups. The Pentagon is expected to detail the changes at a NATO defense ministers' meeting in Brussels this week.

While precise figures vary, earlier reports indicated the cuts could remove roughly 200 U.S. positions from NATO command centers and reduce participation in advisory groups. The move reflects the administration's view that European allies have not done enough to boost their own defense spending and capabilities. But it has already sparked concern among NATO members, who fear it could erode the alliance's deterrence credibility and leave a security gap that Europe is not yet ready to fill.

Burden-Sharing or Breakdown?

Administration officials argue the plan is consistent with Trump's calls for a more equitable distribution of defense costs within NATO. "We want our allies to step up, and this is a way to encourage that," one official said, speaking on condition of anonymity. But European partners see it as a dangerous precedent. "It sends the wrong signal at a time when we need unity," a European diplomat said, adding that allies are scrambling to understand the full scope of the changes.

The reductions come amid heightened tensions with Russia and ongoing debates within the alliance about future strategy. NATO military leaders are already meeting in Brussels to assess challenges, and the U.S. decision complicates those discussions. While some European nations have increased defense spending in recent years, analysts warn that capability building takes time, and immediate gaps could emerge if U.S. support is scaled back.

Broader Implications

The move is part of a broader pattern of U.S. pressure on NATO burden-sharing, including earlier reported reductions in troops on the alliance's eastern flank. If implemented, it could accelerate European defense industrial investment and push NATO to revise contingency plans. However, it also risks deepening mistrust between Washington and some European capitals, potentially driving closer coordination among EU members or bilateral security arrangements.
