Trump's 'Golden Dome' Defence: Is Greenland Ownership Essential for US Missile Shield?

• Donald Trump advocates US ownership of Greenland for national security, linking it to the $175-billion "Golden Dome" missile defence system.
• The "Golden Dome" is a next-generation air and missile defence project aiming to shield the US from advanced threats like ballistic missiles, hypersonic vehicles, and AI-enabled drones.
• Trump argues Greenland's strategic location along Arctic routes is vital for early detection of missile launches and enhancing NATO's Arctic defence.
• Defence experts and officials state that US ownership of Greenland is not necessary, as existing agreements with Denmark provide ample access for defence operations at Pituffik Space Base.
• The Golden Dome's multi-layered architecture allows for distributed components, with alternative basing options in the US (e.g., Fort Drum, New York) and potentially Canada.

Why It Matters: Trump asserts Greenland ownership is crucial for his 'Golden Dome' missile defence, but experts disagree, citing existing access.
