United States vs Denmark: Who Controls Greenland?
Most analysis asks who is stronger. Warlord Intel asks who has leverage.
Short answer
A unilateral US annexation of Greenland would be a self-inflicted wound of historic proportions, effectively shattering the NATO alliance and the post-war liberal order. While direct military conflict with allies is improbable, the diplomatic and economic blowback would cripple US foreign policy and provide a monumental strategic victory for Russia and China.
