Albert Einstein helped persuade President Roosevelt to build the first atomic bomb. But later, in the 1950's, the physicist warned that if a Third World War was fought with the new weapons, there'd be nothing left on earth to fight a Fourth war with but sticks and stones. And there was another threat: accidents. Mishaps and blunders with nuclear weapons have proven much more difficult to avoid than all out war. A new terminology was needed, a way to describe accidents in which nuclear weapons are lost or destroyed - or worse. These incidents became known as "Broken Arrows." The survivors of Broken Arrows insist that understanding the history of nuclear weapons accidents is crucial to global security, especially as the number, nationality and variety of nuclear devices continues to grow.
