Pentagon Cuts Brigade in Europe as Trump Pressures NATO

The Pentagon announced Tuesday it is reducing the number of Brigade Combat Teams (BCTs) stationed in Europe from four to three, returning U.S. troop levels on the continent to their 2021 posture as the Trump administration intensifies pressure on NATO allies to shoulder greater responsibility for Europe’s conventional defense. The move affects approximately 4,000 to 4,700 troops and temporarily delays a planned rotation of the 2nd Armored Brigade Combat Team, 1st Cavalry Division to Poland, according to Fox News.

Context

The reduction marks a significant shift in U.S. military posture in Europe, which had been bolstered following Russia’s full-scale invasion of Ukraine in February 2022. The current drawdown returns troop levels to pre-2022 numbers. It follows President Donald Trump’s earlier announcement in early May to pull approximately 5,000 troops from Germany after Chancellor Friedrich Merz criticized Washington’s handling of the Iran war.

The Pentagon framed the decision as part of a “comprehensive, multilayered process focused on U.S. force posture in Europe” designed to advance Trump’s “America First agenda.” In a statement, the department said the analysis aims at “incentivizing and enabling our NATO allies to take primary responsibility for Europe’s conventional defense.”

Key Developments

Pentagon Chief Spokesman Sean Parnell confirmed that the decision returns BCT levels to those seen in 2021, adding that it results in a “temporary delay” of the deployment of U.S. forces to Poland, which he described as “a model U.S. ally.” According to Deutsche Welle, NATO Supreme Allied Commander Gen. Alexus Grynkewich told reporters in Brussels that the withdrawal would take “several years” and be “well-synchronized” with allies.

Poland, which spends approximately 4.7% of its GDP on defense — the highest proportion in NATO — was caught off guard by the decision. Polish Deputy Defense Minister Paweł Zalewski told Fox News Digital that Warsaw would press U.S. officials for answers during upcoming meetings in Washington. “We will ask questions and I guess that we will get answers,” Zalewski said, as reported by Fox News.

Polish Prime Minister Donald Tusk downplayed concerns, saying he received assurances that the decision was logistical in nature and does not directly impact deterrence capabilities or Poland’s security.

The decision drew bipartisan criticism in Congress. Republican Rep. Don Bacon of Nebraska called the move “reprehensible” and “an embarrassment to our country what we just did to Poland.” Rep. Mike Rogers of Alabama, chair of the House Armed Services Committee, said the military failed to consult lawmakers as required. “So we don’t know what’s going on here,” Rogers said. “But I can just tell you we’re not happy with what’s being talked about,” according to The Independent/AP.

Analysis

The troop reduction reflects multiple motivations. The Trump administration is following through on its stated policy of shifting defense burdens to European allies, using the reduction as leverage to push NATO members toward the 5% GDP spending target agreed upon in June 2025. The cuts also appear partially motivated by allied reluctance to support the U.S.-led war against Iran.

Ben Hodges, former commanding general of U.S. Army Europe, warned that the move “reinforces the perception that the United States just does things without consultation with allies” and ultimately “damages cohesion inside the alliance.” Speaking to the Anadolu Agency, Pentagon spokesman Parnell emphasized that “Poland has shown both the ability and resolve to defend itself. Other NATO allies should follow suit.”

A NATO official said the U.S. decision would not impact the alliance’s deterrence and defense plans, noting that Canada and Germany have increased their presence on the eastern flank, partially offsetting the U.S. reduction.

What’s Next

The Pentagon says it will determine the final disposition of U.S. forces in Europe based on further analysis of strategic requirements and allies’ ability to contribute. Gen. Grynkewich indicated the withdrawal process will unfold over several years. Meanwhile, Congress may attempt to block the reductions through legislation, setting up a potential clash with the White House. European allies are bracing for further reductions and accelerating their own defense investments, raising questions about the long-term future of NATO’s traditional burden-sharing model.
