Leaders of the European Union convened in Brussels to deliberate on defense policy amid escalating threats, notably from Russia.

Nevertheless, a significant portion of the discussion turned to the United States, particularly President Donald Trump's trade disputes and his controversial assertion regarding Greenland.

EU leaders reiterated their commitment to safeguarding Greenland, with European Commission President Ursula von der Leyen cautioning against potential retaliation should the U.S. impose unfair tariffs on the EU. Polish Prime Minister Donald Tusk emphasized the importance of steering clear of a trade conflict and advocated for increased flexibility in defense spending to address the mounting risks from Russia.

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

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

NATO Secretary-General Mark Rutte proposed that NATO could help secure Greenland alongside Arctic partners.

Danish Prime Minister Mette Frederiksen echoed sentiments for greater collaboration in the Arctic region.

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

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

Von der Leyen also indicated a willingness to engage in discussions about enhanced security and defense collaboration with the U.K.
