Danish PM rejected the claims of US President over Greenland.

Strategic Importance of Greenland

• Military and Security Infrastructure: Greenland is a cornerstone of North American and NATO defense due to its geographical position. E.g. crucial for the U.S. ballistic missile early-warning system.
  • It is also ideal for ground stations that track polar-orbiting satellites used for intelligence, navigation, etc.
• Critical Minerals and Natural Resources: contains massive, largely untapped deposits of rare earth minerals.
• Emerging Arctic Shipping Routes: Melting ice is opening the Transpolar Sea Route.
  • These routes could significantly shorten travel times between the Atlantic and Pacific oceans, bypassing traditional chokepoints like the Panama and Suez canals.
