I assume that all of you know the Doomsday Clock, and that the clock is at 7 minutes right now.
But the recent changes in world politics and Iran trying to acquire nuclear weapons, and the uncertainty of what countries have actual nuclear weapons or the means to produce them or sell components crucial on building one.
The world has been in 2 Minutes to Midnight in 1953 to 1960, which has been closest it has been, but numbers have since become more realistic even though the amount of nuclear weapons in the world has increased over ten fold.
This is not your doomsday discussion so no wise crackig please, but genuine input on the matter.
