Getting prepared for alien invasion is surely a stupid thing: Suppose the Soviets were aliens, and tried to invade US.. I am sure US wouldn't hesitate or have a problem with nuking every single sq. mile of Soviet land... Please Register or Log in to view the hidden image! What nuclear weapons do - they make war as it used to be obsolete.. Nobody would dare to invade a country who owns a nuclear weapon - they always have a blackjack to play... That is why this world is much more stable place than it used to be in beginning of 20th century. I think that nobody will ever detonate a nuclear bomb, since it is simply pointless.
