On May 22, 2023, US President Donald Trump announced the deployment of an additional 5,000 troops to Poland, a move that has sparked various reactions and uncertainties regarding troop rotation and NATO's future. The announcement was made on Trump's Truth Social platform, where he cited the election of Polish President Karol Nawrocki as a factor in his decision. Poland's Foreign Ministry stated it has not received further details about the troop deployment, including whether these forces will come from existing units in Europe or represent a new contingent.

Poland is preparing to build infrastructure to accommodate the troops and their families, with Deputy Defense Minister Pawel Zalewski indicating a preference for a permanent presence rather than a rotational one. Polish officials, including Foreign Minister Radoslaw Sikorski, expressed uncertainty about whether the troop increase will raise the total US presence from 10,000 to 15,000 or simply replace existing rotations.

Concerns have arisen in Europe regarding the implications of this decision for NATO's structure and the US's role within the alliance. NATO Secretary General Mark Rutte reassured that the US will continue to play a critical role in European defense despite the reduction of US brigade combat teams in the region.
