> The exact details are hazy, but the broad contours are clear: the inspection team found the control of the forward-based nuclear weapons inadequate and possibly illegal. In Germany and Turkey they viewed scenes that were particularly distressing. On the runway stood a German (or Turkish) quick-reaction alert airplane (QRA) loaded with nuclear weapons and with a foreign pilot in the cockpit. The QRA airplane was ready to take off at the earliest warning, and the nuclear weapons were fully operational. The only evidence of U.S. control was a lonely 18-year-old sentry armed with a carbine and standing on the tarmac. When the sentry at the German airfield was asked how he intended to maintain control of the nuclear weapons should the pilot suddenly decide to scramble (either through personal caprice or through an order from the German command circumventing U.S. command), the sentry replied that he would shoot the pilot; Agnew directed him to shoot the bomb.

The 1950s, 1960s, and 1970s were a wild time. Tens of thousands of deadly devices in the hands of two superpowers armed to the teeth, and not a single rogue general. Not one single device sold to terrorists on the black market. It's a miracle we made it out alive.
