If the United States bought Greenland during the Cold War

How would the Cold War have changed if the United States bought Greenland after building Camp Century, and how would it defend the area against Soviet aircraft?

Clarke expects limited change because American basing access already existed and Arctic operations would remain costly; the answer does not work through a detailed defence against Soviet aircraft.

Clarke treats the proposed purchase as contingent on reaching a deal with Denmark. He expects the cold and expense of operating modern aircraft to limit the number of bases, drawing a comparison with Alaska. His assessment is that Danish NATO membership and existing American access would leave much of the basic basing problem unchanged. Additional facilities are considered possible, but the answer does not develop a plan for intercepting Soviet aircraft.
