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

However, attention largely turned to the United States, where President Donald Trump's trade disputes and his contentious assertion regarding Greenland became focal points.

EU leaders reiterated their dedication to safeguarding Greenland, with European Commission President Ursula von der Leyen cautioning against reprisals if the U.S. enacts unjust tariffs on the EU. Polish Prime Minister Donald Tusk emphasized the importance of steering clear of a trade conflict while advocating for increased flexibility in defense spending to tackle the intensifying threat from Russia.

German Chancellor Olaf Scholz showed support for more adaptable defense funding but dismissed the notion of creating joint EU debt for defense initiatives.

Regarding Greenland, European Council President António Costa affirmed the EU's commitment to upholding Denmark’s territorial integrity.

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

Danish Prime Minister Mette Frederiksen voiced similar calls for improved collaboration in the Arctic region.

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

In an unusual event, U.K. Prime Minister Keir Starmer attended the dinner segment of the summit, marking the first participation since Brexit.

Von der Leyen also expressed a readiness to engage in discussions about deeper security and defense collaboration with the U.K.
