"French President Macron visited Gdańsk in April 2026 to institutionalise the Nancy Treaty. The agreement, in force since 22 January, includes economic, social and cultural components, but its main focus is military cooperation. Poland plans to increase defence spending to 4.8% of GDP, the highest in NATO. France remains Europe's only military power with nuclear deterrence and a full-spectrum defence industry. The partnership aims to bolster NATO's eastern flank security."
