The United States and Poland are advancing plans to establish a permanent U.S. Army base in Poland to expand the American military presence on NATO’s eastern flank. 

Donald Trump has praised Polish President Karol Nawrocki for his leadership in this initiative, describing him as an ‘adventurous friend’ and calling the progress a ‘historic step’ for the American-Polish alliance. Polish Sejm Marshal Włodzimierz Czarzasty expressed support for the move, noting that any action increasing national security is a positive direction.

As the U.S. moves toward a permanent installation, the Pentagon is conducting a broader review of its European military posture. This may involve redistributing approximately 80,000 personnel, potentially including troop reductions in Germany, Italy, and Spain. While the U.S. currently maintains a garrison in Poznan and uses rotational forces, a permanent base would require significant infrastructure development to support several thousand additional personnel and their families. The strategic shift is driven by Poland's geographic proximity to Russia, Belarus, and Ukraine.

On September 18, 2026, President Trump addressed concerns regarding Russian hybrid attacks against Poland and other nations supporting Ukraine. During a White House press conference, Trump reiterated his confidence in President Nawrocki, describing him as a ‘great president’ who ‘has it under control.’

In a related escalation, Trump signed law H.R. 5334, expanding sanctions, tariffs, and prohibitions against Russia and extending restrictions on Iran. These measures include the potential to impose tariffs on goods from countries acting as major importers of Russian oil and gas.
