Remember the 1950's classic sci-fi film "The Day the Earth Stood Still"? Klaatu (Michael Rene) tells the people of the Earth that no aggression will be tolerated to exist any further between the nations of Earth because humans have attained nuclear weapons and the rudiments of space travel. Earth, therefore, has become a potential threat to other worlds. A race of robots ("Gort") has been created to enforce this peace, and absolute power has been given to them. The same idea was presented in "Dr. Strangelove," a computer system would launch total war automatically -- no human intervention. A gun ban would have to be enforced by "Gort."
