US President Donald Trump said Thursday that Washington and Warsaw had made significant progress toward establishing a permanent US military base in Poland. In a post on Truth Social, Trump credited Polish President Karol Nawrocki’s leadership and said the site could be announced “very soon.”

Trump described the possible base as a historic development for the US-Polish alliance. Nawrocki thanked him on X and said Poland was prepared to continue efforts to strengthen defence cooperation, adding that the government would work to provide the best possible location for the US Army.

Zbigniew Bogucki, head of the Polish president’s chancellery, called the announcement “great news for Poland,” according to the supplied source. He also noted that it came on the anniversary of the Soviet invasion of Poland.

The announcement follows discussions disclosed by Warsaw in August about establishing a permanent US military presence. Polish Deputy Defence Minister Pawel Zalewski said at the time that an initial stage of the process had been completed and that political support for the proposal had already been expressed, according to public broadcaster TVP.

The plans are being discussed while the Trump administration conducts a formal review of the US military presence in Europe. The review has prompted concern among allies that Washington could reduce its forces on the continent.

Poland has sought a larger allied presence on NATO’s eastern flank since Russia’s full-scale invasion of Ukraine in 2022. Nearly 10,000 US troops are currently stationed in Poland, but the source said they are deployed almost entirely on a rotational basis. Poland is a NATO and European Union member and allocates about 5% of its gross domestic product to defence spending, the source reported.
