Trump says U.S. ownership of Greenland is crucial for his ‘Golden Dome’ missile defense system. In a hypothetical nuclear war involving Russia, China and the United States, the island of Greenland would be in the middle of Armageddon.The strategic importance of the Arctic territory — under the flight paths that nuclear-armed missiles from China and Russia could take on their way to incinerating targets in the United States, and vice versa — is one of the reasons U.S. President Donald Trump has cited in his disruptive campaign to wrest control of Greenland from Denmark, alarming Greenlanders and longtime allies in Europe alike.Trump has argued that U.S. ownership of Greenland is vital for his “Golden Dome” — a multibillion dollar missile defense system that he says will be operational before his term ends in 2029.“Because of The Golden Dome, and Modern Day Weapons Systems, both Offensive and Defensive, the need to ACQUIRE is especially important,” Trump said in a Truth Social post on Saturday.That ushered in another roller-coaster week involving the semiautonomous Danish territory, where Trump again pushed for U.S. ownership before seemingly backing off, announcing Wednesday the “framework of a future deal” on Arctic security that’s unlikely to be the final word.Here’s a closer look at Greenland’s position at a crossroads for nuclear defense.
