The President of the United States, Donald Trump, announced this Thursday that Washington and Warsaw are moving towards the establishment of a permanent base of the U.S. Army in Poland, an old aspiration of the Polish Government that would acquire special relevance for NATO's military deployment against Russia.
"Great news!" Trump proclaimed on his social network Truth Social. The president assured that "great progress" is being made to establish a U.S. Army base on Polish territory and attributed the progress to the leadership of the President of Poland, Karol Nawrocki.
However, Trump introduced an important caution: the agreement is still not formally closed. "If this happens, the location will be announced very soon," he noted, before describing the eventual establishment of the base as a "historic step" for the alliance between the United States and Poland.
The statement represents the clearest political advance so far of a negotiation that Warsaw formally initiated several months ago and that has accelerated during the summer.
Poland formally requested a permanent base in May
The Polish Government officially conveyed its proposal to Washington on May 29. The Minister of Defense and Deputy Prime Minister, Władysław Kosiniak-Kamysz, asked the Pentagon to establish a permanent U.S. military base in the country.
The response came in June. After meeting with the Pentagon official, Pete Hegseth, Kosiniak-Kamysz announced that the United States had responded "positively" to the proposal, although the conditions for the future deployment remained to be specified.
The Polish Presidency has also made the project a priority. During the NATO summit held in Ankara in July, Nawrocki stated that his goal was to achieve "a permanent presence of U.S. soldiers in Poland in the form of a permanent base" and considered that the political path to achieve it was open.
Negotiations have accelerated in September
The talks have continued over the past few weeks. On September 10, a U.S. delegation led by Deputy Assistant Secretary of Defense William Cappelletti met in Poland with representatives of the Ministry of Defense and the Armed Forces of the country.
According to the official report from the Polish Ministry of Defense, both parties addressed the conditions to reinforce the U.S. military presence, agreed on a general timeline to continue consultations, and decided to establish working groups to negotiate the details. The U.S. delegation also planned to visit the facilities in Powidz and Poznań, where there is already a U.S. military presence.
The negotiation is based on the Enhanced Defense Cooperation Agreement signed between Washington and Warsaw in 2020, which regulates a large part of the U.S. deployment on Polish territory.
Trump did not reveal this Thursday which of the studied locations would host the new base nor did he detail how many military personnel would be permanently assigned to it.
The U.S. already has thousands of military personnel in Poland
The importance of the announcement lies precisely in the difference between the existing U.S. presence and the new facility that both governments are negotiating.
Poland has been hosting U.S. troops for years, a presence particularly reinforced since the Russian invasion of Ukraine. In September 2025, Nawrocki estimated around 10,000 U.S. soldiers deployed on Polish territory.
The United States also has had a permanent Army garrison in Poznań since 2023, which serves as the forward headquarters of the V Corps. But a large part of the forces deployed in the country maintain a rotational character.
What Warsaw seeks now is to take an additional step: a permanent U.S. military base, accompanied by agreed capabilities and infrastructure between both countries.
The aspiration is not new either. Already in 2019, Washington and Warsaw agreed to increase the then presence of approximately 4,500 rotating U.S. military personnel with around another 1,000 troops and new infrastructures.
The move comes as Washington reviews its troops in Europe
Trump's announcement also comes at a particularly sensitive moment for European security. The Pentagon is conducting an assessment of the U.S. military presence in Europe, where there are currently around 80,000 personnel, and among the possibilities being studied is a reduction of part of the contingent.
The review has generated concern among some European allies about the possibility that Washington will shift resources to other strategic priorities. Poland has followed a different strategy: trying to consolidate itself as one of the main pillars of the American presence on NATO's eastern flank.
The security context also weighs on the negotiation. This Thursday, Poland has mobilized aircraft in response to a new Russian wave of missiles and drones against Ukraine, although Polish authorities have not reported violations of its airspace.
Warsaw has been demanding a reinforcement of the defense of Eastern Europe for months in light of the war in Ukraine and the hybrid threats it attributes to Moscow. Nawrocki argued at the last NATO summit that a greater American presence would serve to strengthen the security of the Alliance's eastern flank.
