Poland’s President Andrzej Duda says he has received U.S. assurances that Washington will not reduce its troop presence in Poland and elsewhere along NATO’s eastern flank.

The administration of U.S. President Donald Trump has not announced any plans to pull forces out of the region, but has said Europe must do more to provide for its own security. His administration’s stance has raised questions in the region about whether Washington will maintain its longstanding commitments to NATO partners.
