The United States has officially started a comprehensive review of its military deployment in Europe, a move that could alter the transatlantic security landscape. President Donald Trump, who has long criticized NATO allies for not meeting defense spending commitments, ordered the assessment. The review will examine the size, location, and mission of the roughly 100,000 US troops stationed across the continent, with a particular focus on Germany, home to major bases like Ramstein Air Base.
This review fulfills a promise Trump made during his campaign and presidency to re-evaluate overseas commitments. The Pentagon is leading the effort, which will analyze whether the current force posture aligns with US strategic interests and burden-sharing expectations. Trump has repeatedly argued that European allies, especially Germany, must increase their own defense budgets to reduce the financial strain on American taxpayers.
The review comes at a time when NATO faces internal friction over spending and strategic priorities. While many European nations have pledged to raise defense spending to 2% of GDP, only a handful have met that target. Germany, for example, spends about 1.5% of its GDP on defense, despite committing to the 2% goal. The US sees this as an imbalance that needs correction.
If the review leads to troop reductions, the impact would be most pronounced in countries hosting large US forces, such as Germany, Italy, and Turkey. Smaller NATO members, particularly those near Russia, like Poland and the Baltic states, rely heavily on US troops as a deterrent. Any signal of disengagement could embolden Russia and create uncertainty among allies.
The process is expected to take several months and will involve consultations with NATO partners. However, the final decision rests with the White House. European leaders are watching closely, as the outcome could redefine the US role in European defense for years to come. The review also raises questions about whether the US will shift resources toward the Indo-Pacific, a region Trump has identified as a top priority.
What remains unclear is whether the review is a negotiating tactic to push allies to spend more or a prelude to a significant drawdown. For now, the review itself is a clear signal that the Trump administration is serious about reassessing its global military footprint.
