The US, Denmark, and Greenland have signed a new agreement to expand American military activity on the island. Washington calls Greenland vital to its security, but an expanded military presence also raises an older question: What risks does the Arctic island take on in return?
The agreement builds on a defense partnership dating back to 1951. That history includes an episode that brought the risks of Washington’s Cold War strategy into sharp focus: An American mission over Greenland that ended in a nuclear disaster.
The nuclear patrols over Greenland
In the 1960s, in the middle of the Cold War, the US Air Force launched Operation Chrome Dome. This mission implied keeping bombers armed with nuclear weapons on continuous airborne alert, ready to strike the USSR if necessary. If you’ve seen the film ‘Dr. Strangelove’, you’ll remember that Major T.J. ‘King’ Kong’s crew was involved in such a patrol mission.
Theoretically, this strategy was feasible: It would have made it impossible for the USSR to disarm the US with a single blow. However, in practice, as the number of nuclear-armed aircraft patrols increased, so did the number of incidents involving nuclear weapons.
Then-US Secretary of Defense Robert McNamara advocated for ending this program, arguing that Americans had already established an effective early warning system for ballistic missile launches, so the US could take fewer risks and cut costs. However, the Strategic Air Command resisted this idea, fearing it would decrease their importance and result in budget cuts.
A horrific incident occurred in 1966 over Spain when a bomber collided with a refueling tanker aircraft, resulting in several fatalities and nuclear bombs landing on beaches and in the Mediterranean Sea. Despite this incident, the US considered the nuclear threat from the USSR a matter of primary importance, one which justified any security measures.
Eventually, after intense debates, a compromise was reached: The number of patrolling bombers would be reduced, but the airborne patrols would continue.
Thule Air Base in northern Greenland was established in the 1950s. A Mercator projection map gives a distorted sense of distance; in reality, its location was very convenient for potentially launching missiles at the USSR and monitoring missile launches from there. It also provided a convenient vantage point for reconnaissance of the Novaya Zemlya Soviet nuclear test site.
