President Donald Trump’s aggressive stance on Greenland has disrupted global politics, sparking European concern, challenging NATO cohesion, and raising fears of a world without rules.

European leaders rally behind Denmark after President Trump threatens tariffs over Greenland, warning that economic coercion could damage NATO unity and global stability.

The White House says President Donald Trump is considering multiple options to acquire Greenland, including potential military action, calling it a US national security priority. European leaders and Greenland’s government have rejected the idea, warning it could violate international law and strain NATO unity.
