Germany and Poland Sign Landmark Defense Cooperation Agreement in Warsaw

On June 17, 2026, Germany and Poland formally enhanced their defense partnership by signing a new defense cooperation agreement in Warsaw. This signing coincides with the 35th anniversary of the German-Polish Neighborhood Treaty and marks a significant step in strengthening military collaboration between the two NATO and EU member states.

German Defense Minister Boris Pistorius traveled to Warsaw to finalize the agreement, which reiterates the mutual assistance commitments both countries hold within the frameworks of NATO and the European Union. The accord emphasizes closer collaboration on military capability development, joint exercises, and cooperation in the arms industry.

Knut Abraham, the German government's representative for German-Polish relations, underscored the agreement’s importance given the unpredictable reliability of the United States as a defense partner, highlighting the critical need for stronger European solidarity. Abraham also contextualized the improved cooperation by acknowledging the historically difficult relationship between Germany and Poland, burdened by memories of World War II German occupation crimes. He expressed that Germany aims to involve Poland more actively in European decision-making to foster a balanced and equitable partnership.

The signing also occurred amid ongoing discussions about expanding political relations between the two countries, featuring talks between Germany’s CDU Foreign Minister Johann Wadephul and Polish Foreign Minister Radoslaw Sikorski at the German-Polish Forum in Berlin. Progress in bilateral ties has been significant but still requires overcoming historical tensions. One positive sign noted by Abraham was the potential removal of border controls, which may ease tensions in border regions and promote smoother relations.

This defense cooperation agreement symbolizes a deepened commitment to joint security in Central Europe, reinforcing the transatlantic alliance through shared European responsibility and collaboration.
