EU defense clause could shield Greenland if the US advances on Denmark, but hurdles loom
Denmark could invoke the EU’s Article 42.7 mutual defense clause to aid Greenland if the US or a NATO ally attacks, offering a path that does not require EU troops but hinges on unanimous EU approval and politics; the EU has no standing army, and applicability to Greenland is unclear, creating significant legal and political hurdles before it could lead to any concrete military or diplomatic actions, potentially reshaping Europe’s security approach if invoked.
