The abundance of nuclear weapons is an imminent danger which could cause a worldwide catastrophe. I know that we have some of these weapons to protect us. But you have to take into consideration that if the wrong hands got one of these weapons. Not only would it take out a state, it would take out America and maybe other countries as well depending on how powerful the nuclear weapon is. There are over 20 nations with nuclear power and the list seems to be growing. If one of these nations happen to set off one of the nuclear weapons by accident, it would be catastrophic.
