The Pentagon is quietly looking at a massive shift. Right now, about 80,000 American service members are stationed across Europe. Washington is actively weighing plans to pull out anywhere from 25,000 to 40,000 of them.
If this goes through, it cuts the US military presence on the continent by nearly a third. It is a big deal.
Let's break down what is actually driving this review, which countries stand to lose the most personnel, and why European defense capitals are already sounding the alarm.
The Timeline and the Decision-Makers
This isn't happening overnight. The potential drawdown is part of a strict six-month Pentagon review of US military posture overseas.
General Alexus Grynkewich, who pulls double duty as the head of US European Command and NATO’s Supreme Allied Commander Europe, has been tasked with putting together initial assessments. His reports outline various choices involving ground units, naval assets, and air power. Some options even point toward shifting a fraction of remaining forces eastward, closer to the Russian border, rather than sending them straight back to American soil.
Defense Secretary Pete Hegseth is scheduled to receive the final recommendations on November 6. From there, the proposal lands on President Donald Trump’s desk for a final call.
Nothing is carved in stone yet, but the friction behind the scenes is real. Word leaked that Secretary of State Marco Rubio stepped in earlier to pump the brakes when the Pentagon tried briefing NATO defense ministers too early on deep cuts.
Which Countries Will Feel the Impact First?
If the cuts hit the 25,000-to-40,000 troop threshold, the footprint in Western and Southern Europe will shrink fast.
Nations hosting the largest US contingents are naturally first in line for downsizing. Germany, Italy, and Spain sit squarely at the top of that list. Germany alone hosts tens of thousands of US personnel, serving as the logistical backbone for American operations in the region.
Political tension plays a subtle role here, too. Some of these host governments have recently clashed with Washington over foreign policy stances, including military actions in the Middle East. That friction gives extra momentum to an administration that has long insisted European nations need to pay for and manage their own conventional security.
The Strategic Fallout for NATO
Washington’s argument boils down to shifting finite military resources toward other global theaters while forcing wealthy European allies to step up. But critics on both sides of the Atlantic argue the timing is terrible.
Lawmakers from both parties have spoken out, warning that a sudden, mass withdrawal weakens deterrence against Russian aggression. You cannot do security on the cheap. When you pull tens of thousands of troops, combat aircraft, and naval assets out of a theater, you leave gaps that local militaries cannot fill overnight.
Even so, countries on NATO's eastern flank look at the situation through a different lens. While Western European bases might empty out, eastern allies are pressing to ensure that any remaining American footprint pivots directly toward their borders to face Moscow's ongoing threats.
Keep a close eye on Washington this November. When the final recommendations drop, Europe's defense landscape is going to change in a hurry.
