WASHINGTON (AP) — The United States will withdraw about 5,000 troops from Germany in the next 6-12 months, the Pentagon said Friday.

President Donald Trump had threatened to withdraw some troops from the NATO ally earlier this week as he continues to feud with Chancellor Friedrich Merz over the U.S-Israel war against Iran. Merz said the U.S. was being “humiliated” by the Iranian leadership and criticized Washington’s lack of strategy in the war.

Pentagon spokesman Sean Parnell said in a statement that the “decision follows a thorough review of the Department’s force posture in Europe and is in recognition of theater requirements and conditions on the ground.”

The U.S. has several major military facilities in Germany, including the headquarters for U.S. European Command and U.S. Africa Command, Ramstein Air Base and Landstuhl Regional Medical Center, the largest American hospital outside the United States.

The number of troops leaving Germany would be 14% of the 36,000 American service members stationed there.

Nico Lange from the Center of European Policy Analysis told The Associated Press earlier this week that they primarily serve U.S. interests, including “the projection of American power globally,” rather than helping with the defense of Germany.

Trump ignored questions from reporters about the withdrawal on Friday as he boarded Air Force One in Ocala, Florida, following a rally to tout his economic agenda.

Trump made a similar threat in his first term, saying he would pull about 9,500 of the roughly 34,500 U.S. troops who were then stationed in Germany, but he didn’t start the process and Democratic President Joe Biden formally stopped the planned withdrawal soon after taking office in 2021.

The mercurial U.S. leader has mused for years about reducing the American military presence in Germany, and has railed against NATO for its refusal to assist Washington in the war, which began on Feb. 28 with U.S.-Israeli strikes on Iran.

Trump wrote Wednesday on social media that the U.S. was reviewing possible troop reductions in Germany, with a “determination” to be made soon. On Thursday, he was still thinking about Merz, posting that the German leader should “spend more time on ending the war with Russia/Ukraine” and “fixing his broken Country” than concerning himself with Iran.

American allies in NATO have braced for a U.S. troop withdrawal since Trump took office, with Washington warning that Europe would have to look after its own security, including that of Ukraine, in the future.

Depending on operations, exercises and troop rotations, around 80,000-100,000 U.S. personnel are usually stationed in Europe. NATO allies have expected for more than a year that the U.S. troops deployed after Russia launched its all-out war on Ukraine in February 2022 would be first to leave.

Ed Arnold, an expert in European security at the Royal United Services Institute, or RUSI, in London, said Europe is more concerned about issues like a U.S. redeployment of Patriot missile systems and ammunition from Germany to the Middle East.

In October, the U.S. confirmed that it would reduce its troop presence on NATO’s borders with Ukraine. The move to cut 1,500-3,000 troops came on short notice and unsettled NATO ally Romania, where the military organization runs an air base.
