U.S. President Donald Trump announced that Washington will deploy an additional 5,000 troops to Poland, linking the decision directly to his close relationship with Polish President Karol Nawrocki. The announcement, made on Truth Social, came amid growing uncertainty over the future of the American military presence in Europe and only days after reports that a previously planned troop rotation to Poland had been delayed.

“Based on the successful Election of the now President of Poland, Karol Nawrocki, who I was proud to endorse, and our relationship with him, I am pleased to announce that the United States will be sending an additional 5,000 Troops to Poland,” Trump wrote.

The move appears to reverse a Pentagon decision announced earlier this week to postpone the deployment of around 4,000 troops from the 2nd Armored Brigade Combat Team, 1st Cavalry Division, as part of a broader review of U.S. force posture across Europe. Just two days earlier, Vice President JD Vance had defended the delay, calling it “a very minor thing” and “a standard delay.”

At present, roughly 10,000 American troops are stationed in Poland, NATO’s largest military hub on the alliance’s eastern flank. It remains unclear whether the newly announced deployment will be permanent or rotational, or whether it is connected to the recent withdrawal of 5,000 U.S. troops from Germany following tensions between Trump and German Chancellor Friedrich Merz.
