US-Denmark Tensions Rise Over Greenland Amid Security Concerns and NATO Responses

US President Donald Trump has reiterated his demand for American control over Greenland, citing its strategic importance for national security and a missile defense system called the Golden Dome. Trump warned that if the US does not acquire Greenland, rivals like Russia or China might, framing this as vital for NATO's effectiveness. Denmark and Greenland, which govern the island as an autonomous territory within the Danish kingdom, firmly reject any transfer of sovereignty. High-level talks between US, Danish, and Greenlandic officials have failed to resolve these differences. In response, Denmark and several European NATO allies have increased military presence and planned joint exercises in Greenland to assert sovereignty and security cooperation. Russia has criticized NATO's military buildup as unfounded, while public opinion in the US largely opposes the acquisition. The situation has raised concerns about NATO unity and Arctic security amid competing geopolitical interests and Greenland's economic reliance on subsidies and fishing.
