1. Greenland
Greenland might seem an unlikely destination for U.S. troops, but during World War II, American forces occupied the island to block Nazi ambitions in the North Atlantic. This strategic move mirrored the U.S. intervention in Iceland, ensuring crucial supply routes remained secure. After the war, the U.S. maintained a military presence, most notably at Thule Air Base, a site that remains vital for missile warning and space surveillance. Greenland’s location continues to make it a key piece in America’s global defense puzzle.
