WASHINGTON, Jan 20 (Reuters) - The United States plans to reduce the number of personnel it has stationed within several key NATO command centers, a move that could intensify concerns in Europe about Washington's commitment to the alliance, three sources familiar with the matter said this week.
As part of the move, which the Trump administration has communicated to some European capitals, the U.S. will eliminate roughly 200 positions from the NATO
entities that oversee and plan the alliance's military and intelligence operations, said the sources, who requested anonymity to discuss private diplomatic conversations.
Among the bodies that will be affected, said the sources, are the UK-based NATO Intelligence Fusion Centre and the Allied Special Operations Forces Command in Brussels. Portugal-based STRIKFORNATO, which oversees some maritime operations, will also be cut, as will several other similar NATO entities, the sources said.
The sources did not specify why the U.S. had decided to cut the number of staff dedicated to the NATO roles, but the moves broadly align with the Trump administration's stated intention to shift more resources toward the Western Hemisphere.
The Washington Post first reported the decision.
TRUMP RE-POSTS MESSAGE IDENTIFYING NATO AS THREAT
The changes are small relative to the size of the U.S. military force stationed in Europe and do not necessarily signal a broader U.S. shift away from the continent. Around 80,000 military personnel are stationed in Europe, almost half of them in Germany.
But the moves are nonetheless likely to stoke European anxiety about the future of the alliance, which is already running high given U.S. President Donald Trump's stepped-up campaign to wrest Greenland away from Denmark, raising the unprecedented prospect of territorial aggression within NATO.
On Tuesday morning, the U.S. president, who is scheduled to fly to the World Economic Forum in Switzerland in the evening, shared another user's post on social media that identified NATO as a threat to the United States. The post described China and Russia as merely "boogeymen."
Asked for comment, a NATO official said changes to U.S. staffing are not unusual and that the U.S. presence in Europe is larger than it has been in years.
"NATO and U.S. authorities are in close contact about our overall posture – to ensure NATO retains our robust capacity to deter and defend," the NATO official said.
The White House and the Pentagon did not respond to requests for comment.
MILITARY IMPACT UNCLEAR, SYMBOLIC IMPACT OBVIOUS
Reuters could not obtain a full list of NATO entities that will be affected by the new policy. About 400 U.S. personnel are stationed within the entities that will see cuts, one of the sources said, meaning the total number of Americans at the affected NATO bodies will be reduced by roughly half.
Rather than recalling servicemembers from their current posts, the U.S. will for the most part decline to backfill them as they move on from their positions, the sources said.
The drawdown comes as the alliance traverses one of the most diplomatically fraught moments in its 77-year history.
Trump famously threatened to withdraw from NATO during his first presidential term and said on the campaign trail that he would encourage Russian President Vladimir Putin to attack NATO members that did not pay their fair share on defense.
But he appeared to warm to NATO over the first half of 2025, effusively praising NATO Secretary-General Mark Rutte and other European leaders after they agreed to boost defense spending at a June summit.
In recent weeks, however, his administration has again provoked alarm across Europe.
In early December, Pentagon officials told diplomats that the U.S. wants Europe to take over the majority of NATO's conventional defense capabilities, from intelligence to missiles, by 2027, a deadline that struck European officials as unrealistic.
A key U.S. national security document released shortly after called for the U.S. to dedicate more of its military resources to the Western Hemisphere, calling into question whether Europe will continue to be a priority theater for the U.S.
In the first weeks of 2026, Trump has revived his longstanding campaign to acquire Greenland, an overseas territory of Denmark, enraging officials in Copenhagen and throughout Europe, many of whom believe any territorial aggression within the alliance would mark the end of NATO.
Over the weekend, Trump said he would slap several NATO countries with tariffs starting February 1 due to their support for Denmark's sovereignty over the island. That has caused European Union officials to mull retaliatory tariffs of their own.
