WASHINGTON, D.C., United States | August 27, 2026 —
Trump NATO troop review has entered a critical new phase, with the Pentagon preparing at least four options for the future deployment of roughly 80,000 U.S. military personnel stationed across Europe.
The options are expected to reach Defense Secretary Pete Hegseth by November 6, ahead of the Pentagon’s formal December deadline for completing its review of America’s European military footprint.
The review could ultimately recommend changes to U.S. troop levels, bases or military support across NATO countries.
But one point is crucial:
The Trump administration has not yet announced a withdrawal of 80,000 U.S. troops from Europe.
The Pentagon is developing multiple options, and the final outcome remains undecided.
Why the Pentagon Is Reviewing US Troops in Europe
President Donald Trump has repeatedly argued that European NATO members should shoulder a larger share of the cost and responsibility for defending the continent.
His administration has also signaled that U.S. forces may increasingly provide more limited support while European allies take the lead in their own regional defense.
The current Pentagon review examines whether America’s military presence in Europe still matches Washington’s wider strategic priorities.
That includes not only troop numbers but also bases, intelligence infrastructure, cyber capabilities, space systems and access to allied territory.
Around 80,000 US Troops Are Currently in Europe
The United States maintains approximately 80,000 military personnel across Europe.
Those forces support NATO deterrence, training, intelligence, air operations, logistics and defense planning.
The U.S. presence stretches across multiple NATO countries and has long been a central part of Europe’s post-Cold War security architecture.
Any significant reduction would therefore affect much more than the number of American soldiers stationed overseas.
It could change how NATO plans for crises and how much military responsibility European governments must assume themselves.
Pentagon Will Prepare at Least Four Options
The review is expected to produce a spectrum of possible force arrangements rather than one predetermined recommendation.
That could allow policymakers to compare different combinations of troop levels, locations and military capabilities.
A key internal decision briefing involving senior U.S. military leadership in Europe and Pentagon policy chief Elbridge Colby is scheduled by September 18.
The resulting options are expected to be presented to Hegseth by November 6.
The details emerging today are significant because they provide a clearer timeline for when Washington may begin making major decisions about its European posture.
Trump Has Pressured NATO Allies Over Defense Spending
Trump has spent years criticizing NATO members that he believes rely too heavily on U.S. military protection.
Under his administration, burden-sharing has become a central test of Washington’s relationship with European allies.
The Pentagon review will consider whether NATO members have credible plans to meet their defense-spending commitments and whether they can fill military-capability gaps as the United States changes its own contribution.
For European governments, the message is increasingly clear:
Washington expects them to provide more money, equipment and military capability for their own defense.
Access to Bases and Airspace Is Also Under Review
The Pentagon is not judging allies only on defense budgets.
Another major issue is what officials call access, basing and overflight, or ABO.
The United States depends on allied countries to allow American forces to use bases, move equipment and fly through their airspace.
Those permissions become particularly important during military crises.
The review will examine whether allied governments reliably provide that access and whether restrictions could interfere with U.S. military operations.
Iran War Has Added New Tension With NATO Allies
The review has become more politically sensitive because of disagreements surrounding the U.S.-Israeli conflict with Iran.
Trump has expressed frustration with some European allies that he believes provided inadequate support during the war.
Concerns included access to bases and permission for U.S. military aircraft to use allied airspace.
That has increased fears in Europe that future American troop decisions could reflect not only NATO defense requirements but also Washington’s assessment of how supportive individual allies are of broader U.S. foreign-policy priorities.
Could Trump Pull Large Numbers of Troops From Europe?
It is possible that troop reductions will be among the options considered.
But no final large-scale withdrawal has been announced.
The Pentagon says its review is intended to examine a range of possible force levels and deployments.
That could include maintaining significant forces while changing locations or capabilities.
It could also include reductions if Washington decides European allies can assume more responsibility.
Until Hegseth and ultimately the Trump administration select a course of action, headlines claiming that America has already decided to remove its 80,000 troops would be premature.
Why NATO Countries Are Worried
European governments have spent decades building defense plans around a major U.S. military presence.
American forces provide capabilities that are difficult to replace quickly, including advanced intelligence, logistics, air power, command systems and strategic support.
A major U.S. reduction could force Europe to accelerate spending on its own military capabilities.
That could create enormous demand for defense equipment, personnel and infrastructure.
It could also change NATO’s internal balance by making European states responsible for more of the alliance’s day-to-day deterrence.
Cyber, Space and Intelligence Are Part of the Review
Modern military power is not measured only in troops and tanks.
The Pentagon review also considers infrastructure connected to:
cyber operations, space capabilities and intelligence systems.
These capabilities allow U.S. forces to monitor threats, coordinate military operations and project power beyond Europe.
That makes the review much broader than a simple question of whether American soldiers should stay or leave.
The Pentagon is effectively reassessing how Europe fits into America’s global military strategy.
What It Could Mean for Russia
Any substantial reduction in U.S. forces would inevitably attract attention in Moscow.
NATO’s European military posture is designed in large part to deter threats from Russia.
European governments are therefore likely to argue that any American drawdown must avoid creating security gaps.
For Washington, however, the calculation also involves competing priorities in Asia, the Middle East and elsewhere.
Moving military resources away from Europe could allow the United States to devote more capabilities to other strategic theaters.
Trump Wants Allies to Take the Lead
One of the clearest themes emerging from the administration is that European allies should increasingly lead the defense of Europe.
That does not necessarily mean the U.S. will leave NATO or abandon the continent.
It could instead mean a different division of labor.
European countries might provide more frontline conventional forces while the United States concentrates on specialized capabilities and strategic support.
The final force review could show how far Trump is willing to push that transition.

NATO Allies Face a New Deadline
The review also involves questionnaires sent to allied governments.
Washington is seeking information on defense spending, military strategy, procurement and support for U.S. policy priorities.
Countries are also being asked about restrictions involving American access to bases and airspace.
That means the Pentagon is not evaluating its own troops in isolation.
It is also evaluating the behavior and military contributions of the countries hosting or supporting those forces.
What Happens Next
The first important date is September 18, when senior officials are expected to discuss potential options.
The second is November 6, when Hegseth is expected to receive at least four sets of force-posture choices.
The wider review is due to be completed in December.
Only after those stages will it become clearer whether the administration intends to maintain, relocate or significantly reduce U.S. forces in Europe.
What the NATO Review Does — and Does Not Mean
The Pentagon review means Trump’s administration is seriously reassessing America’s European military presence.
It does not mean the United States has already decided to withdraw 80,000 troops.
It also does not mean NATO is being dissolved or that every U.S. base in Europe is under immediate threat.
The most consequential question is whether the review results in a gradual shift toward European-led defense—or a much deeper reduction in America’s military footprint.
For NATO governments, that answer could reshape defense planning for years.
For Trump, the review is another test of one of his longest-running foreign-policy arguments:
America’s allies should carry more of the burden for their own security.
