Although some of the recently announced changes to U.S. troops levels in Europe have been signaled for a year or more, they have nonetheless unnerved America’s allies and potentially emboldened Moscow. American troops have been in Europe for decades not merely to underwrite NATO treaty commitments but more specifically to safeguard the country’s most important trading and investment relationship in the world.
Cutting U.S. troops in Europe places transatlantic trade and investment ties in jeopardy, but additionally, the decision represents a potential missed opportunity – Washington risks giving away something for nothing. Russia wants U.S. troop reductions in Europe, and it’s not too late for the United States to get something in return from Moscow.
Cutting U.S. troops in Europe now carries great risk, but if troops must leave, bargaining with Russia makes far more sense than cutting unilaterally. Doing so could reduce the threat posed by Russian forces to NATO, it could facilitate an end to Russia’s war in Ukraine, and it could lower the risk posed to the transatlantic trade and investment relationship.
Earlier this month, the United States notified its NATO allies that it would reduce the number of forces it makes available to NATO for the implementation of the alliance’s operations plans. These plans – approved by all allies – were developed by NATO’s American-led military headquarters in Mons, Belgium, and they are largely focused on the defense of allied territory against Russia. The alliance uses the plans to build a list of the required military forces, and then those requirements are apportioned among the individual allies, building a country-by-country capability target list.
The reduced commitments unveiled by the United States earlier this month were, in many ways, expected. They’ve been signaled by American leaders for at least a year, most notably in February 2025 when Secretary of Defense Hegseth announced that Europeans would need to take the lead in conventional defense of Europe.
But keen observers of NATO understand that this trend has been unfolding for years. Between 2017 and 2025, the proportion of all capability targets assigned to the United States dropped from 46 percent to 38 percent. At the same time, the number of high-end, “exquisite” capabilities provided by the United States, such as advanced air defense, were reduced from 13 (out of 26 total) to 5.
In other words, America has long been on the path of reduced commitments in European defense planning, in the name of fair burden-sharing as well as the shifting of U.S. resources to the Indo-Pacific. The latest changes are the result of dialogue between American and European defense planners as well as between U.S. military officials based in Europe and those based in the Indo-Pacific.
These latter discussions, and the analyses that informed them, were necessary to truly assess what was needed by American military leaders based in the Pacific. It should come as no surprise therefore to see that naval and air forces are reportedly on the list of what the United States will no longer make available to fulfill the NATO operations plans.
Coincidentally and largely unrelated to American capability targets and NATO plans, the United States also announced in early May that it would withdraw 5,000 troops from Europe. This decision, in contrast to the one described above, reportedly came as a surprise.
Initially, American military leaders decided that the largest portion of those 5,000 troops would come in the form of a 4,200-person tank brigade deployed to Poland on a rotational basis. However, that decision was quickly reversed following conversations between top American and Polish leaders. Now American military officials in the Pentagon and in Europe are wrestling with how to implement the cut, perhaps considering drawing down U.S. forces that are permanently stationed (usually with families) in places like Germany, Poland, Italy, Spain, Turkey or the U.K.
Reducing American troops stationed in or rotationally deployed to Europe makes little sense for several reasons. First, most of those troops are ground forces, which are unlikely to be as important for a conflict in the Indo-Pacific. Second, basing U.S. troops in Europe can be cheaper than stationing them in the United States, especially when European allies like Poland or Lithuania pick up the costs. And third, U.S. reductions while Russia’s war in Ukraine rages on sends the wrong message to allies and enemies alike.
Even if none of these things were true and it made great sense operationally, fiscally, and strategically to withdraw U.S. forces from Europe, doing so in exchange for nothing amounts to a very bad deal.
Moscow has made clear it doesn’t want U.S. forces based in Europe, so why not bargain with Russia and get something in exchange?
This is precisely what U.S. officials did a generation ago as the Cold War came to an end – they negotiated simultaneous reductions in conventional and nuclear arms with Moscow.
It’s not too late – if Washington is intent on reducing troop levels in Europe, it can still wield this bargaining chip. In exchange for a 5,000 troop cut in U.S. forces based in Europe, Washington could demand Russia end its war in Ukraine, eliminate the military bases it’s been building up near NATO borders, or cease its hybrid war against U.S. and European interests across Europe and North America.
Something – really, anything – is better than nothing.
