Leaders of the European Union convened in Brussels to address defense policy in light of escalating threats, particularly those stemming from Russia.

However, significant attention was directed toward the United States, with President Donald Trump's trade disputes and his controversial assertion regarding Greenland taking precedence.

EU leaders reiterated their dedication to safeguarding Greenland, as European Commission President Ursula von der Leyen cautioned against potential retaliation if the U.S. enforces unfair tariffs on the EU. Polish Prime Minister Donald Tusk emphasized the necessity to prevent a trade confrontation, while advocating for increased flexibility in defense spending to tackle the intensifying threat from Russia.

German Chancellor Olaf Scholz expressed support for more adaptable defense financing but dismissed the notion of issuing joint EU debt for defense initiatives.

Regarding Greenland, European Council President António Costa affirmed that the EU would uphold Denmark's territorial sovereignty.

NATO Secretary-General Mark Rutte proposed that NATO could ensure security for Greenland with assistance from Arctic allies.

Danish Prime Minister Mette Frederiksen reinforced the call for strengthened collaboration in the Arctic region.

The summit also addressed the divisions within the EU concerning military expenditures and arms procurement, with countries like France pushing for a 'Buy European' policy.

In a noteworthy development, U.K. Prime Minister Keir Starmer attended the dinner segment of the summit, marking the first instance since Brexit.

Von der Leyen also expressed readiness to explore deeper security and defense collaboration with the U.K.
