The United States will withdraw about 5,000 troops from Germany over the next six to 12 months, the Pentagon announced Friday, following through on a warning from U.S. President Donald Trump amid escalating tensions with Berlin.

The move comes after a public dispute with German Chancellor Friedrich Merz, who criticized Washington’s handling of the Iran conflict and suggested the U.S. was being “humiliated” by Tehran.

Pentagon spokesperson Sean Parnell said the decision followed a review of U.S. force posture in Europe and reflects evolving operational needs.

Germany hosts key American military installations, including Ramstein Air Base and the headquarters for U.S. European and Africa commands, as well as a major military medical center in Landstuhl. About 36,000 U.S. service members are currently stationed in the country, meaning the planned reduction would account for roughly 14% of that presence.

The announcement drew criticism from Democrats and defense analysts, who warned the move could weaken NATO’s deterrence and benefit Vladimir Putin. Sen. Jack Reed called the withdrawal “reckless,” arguing it could undermine long-term U.S. security and alliances.

Experts also noted that U.S. forces in Germany play a critical role in projecting military power into Europe, the Middle East, and Africa.

Trump did not address questions about the decision while departing Florida on Friday. During his first term, he proposed a similar troop reduction, though the plan was never implemented and was later halted under the administration of Joe Biden.
