24. The DEW Line: Cold War Cooperation
During the Cold War, the Distant Early Warning Line stretched 3,000 miles across Arctic Canada. It was a chain of radar stations watching for Soviet bombers. This $300 million joint project combined American technology with Canadian territory. The installations employed both nationalities in Earth’s harshest environments. This massive undertaking demonstrated complete trust during a nuclear standoff with the USSR. The project showed how external threats dissolved bilateral tensions.
