US President Donald Trump announced on Thursday that the United States will deploy an additional 5,000 troops to Poland, citing his personal relationship with Polish President Karol Nawrocki as a key reason for the decision. Trump made the announcement via his Truth Social platform, writing that the deployment was based on the "successful election" of Nawrocki, whom he had endorsed. The announcement came just one week after the Pentagon abruptly cancelled a planned deployment of 4,000 rotational troops to Poland — a decision that had prompted alarm in Warsaw and confusion among US allies.
Poland, which borders Ukraine and serves as a critical anchor of NATO's eastern flank, currently hosts around 10,000 US troops on a permanent and rotational basis. The country spends approximately 4.7 percent of its GDP on defence — the highest share of any NATO member relative to the size of its economy — and has long been described by Pentagon officials as a "model ally." Following last week's cancellation, Pentagon spokesperson Sean Parnell called the halt a "temporary delay" linked to a US decision to reduce the number of combat brigades assigned to Europe from four to three, stressing that Washington intended to maintain a strong military presence in Poland. Polish Defence Minister Władysław Kosiniak-Kamysz said he had received assurances that Poland would be included in discussions about the restructuring of US forces on the continent.
Trump's announcement adds a layer of complexity to an already turbulent picture of US military commitments in Europe. Earlier this month, the Pentagon announced the withdrawal of 5,000 troops from Germany, a move that followed a public spat between Trump and German Chancellor Friedrich Merz. It remains unclear whether the troops now headed to Poland are the same soldiers being pulled from Germany, or an entirely separate deployment. Trump has not provided operational details.
The broader context is one of mounting tension between Washington and its European NATO partners. Trump has repeatedly questioned the alliance's value, threatened to withdraw from it, and criticised European governments for their reluctance to join US pressure on Iran over the Strait of Hormuz. Nawrocki, a conservative nationalist whose political outlook broadly aligns with Trump's and who took office in August 2025, has been a vocal Trump supporter, previously telling the BBC that Trump is "the only world leader capable of stopping Vladimir Putin."
The troop announcement lands on the eve of a NATO foreign ministers' summit in Helsingborg, Sweden, where US Secretary of State Marco Rubio is expected to press allies on burden sharing. Rubio has indicated that questions about the overall size of the US force commitment to NATO's collective defence will be on the agenda. Several Republican lawmakers have already criticised the Germany withdrawal, warning it risks sending the wrong signal to Russia at a critical moment in the war in Ukraine.
