In 1961, President Kennedy issued a letter to all American citizens, warning them about the threat of nuclear Armageddon. His solution was to build fallout shelters. The letter read, in part:
“We owe that kind of insurance to our families and to our country. The time to start is now. In the coming months, I hope to let every citizen know what steps he can take without delay to protect his family in case of an attack. I know you would not want to do less.”
