How safe is it to have even one nuclear weapon?
When I was a child, my school would have nuclear attack drills, which involved quickly climbing under a desk of walking quickly to the basement of the school. I think the general strategy was to go somewhere special to essentially kiss your ass goodbye. That was in the 1960's where a neighbor in Florissant had actually built a bomb shelter in the front yard, and you can still see the entry to that shelter. In the decade since the 1960s, I've gradually stopped thinking so much about the world's arsenal of nuclear weapons, even though they are extremely dangerous to possess, even for a country that has them for the supposed purpose of using them against another county. See time code 1:17 of this excellent documentary by Eric Schlosser, "Command and Control," where it is revealed that a declassified military report indicates that there have been more than 1,000 U.S. accidents involving nuclear weapons, at least 31 of these posing serious risks of accidental detonation, risking the lives of countless Americans. It is a miracle that none of these have resulted in nuclear detonations. From the American Experience Website: "Based on the critically-acclaimed book by Eric Schlosser, this chilling documentary exposes the terrifying truth about the management of America’s nuclear arsenal and shows what can happen when the weapons built to protect us threaten to destroy us."
