The announced reduction of US troops in Europe is causing alarm within the alliance. Poland's Prime Minister Donald Tusk speaks of a "disastrous trend" and demands urgent action from partners. WARSAW. – In light of deep cracks in the transatlantic alliance, Polish Prime Minister Donald Tusk has issued an urgent warning to NATO partners. He described the current developments as the "ongoing disintegration" of the alliance and warned of a "disastrous trend." "The greatest threat to the transatlantic community are not its external enemies, but the ongoing disintegration of our alliance," Tusk wrote on the platform X (formerly Twitter). At the same time, he urged coordinated efforts from member states to urgently counter this development. Reaction to Troop Withdrawal from Germany Tusk's clear words came just hours after Washington officially announced plans to withdraw around 5,000 US troops from Germany. This step apparently marks only the beginning of more far-reaching changes: Earlier in the week, US President Donald Trump stated that the United States was considering a comprehensive reduction of its military presence in Europe, including Germany. This was preceded by a diplomatic exchange of blows in which German Chancellor Friedrich Merz accused the US administration of failing to pursue a clear strategy in the Iran conflict. Trump Also Threatens Italy and Spain The tensions within NATO are not limited to the German-American relationship. Trump has openly expressed his displeasure with other alliance partners. The US President has also floated the idea of reducing American troop deployments in Italy and Spain. Trump justified this by stating that these countries had provided insufficient support during the Iran war.
