All-Out-Nuclear-War is going to destroy humanity. The U.S. dropping of nuclear weapons on japan, and testing of these weapon is too much of threat for other nations not to take notice. The attempt by head of states to prevent other nations from having these weapons is futile. If we do not eradicate the U.S. stockpile, then we are in for a bumpy road, and can not expect other nations to follow suit. You can say good bye to the world of char.
