Actually, nuclear weapons went far too close in the Cold War to destroying the ENTIRE EARTH.
Khrushchez had plans for an armagedden bomb to be built, that should COMMUNISM EVER FAIL, the ENTIRE WORLD would be DESTROYED!
Luckily Khrushchez scrapped that idea and it has since never been tried again. But what if someone suddenly had the idea and power to do it, should say the U.S.A. would be destroyed or Islam defeated etc.
Nuclear prevention can probably be attempted without having nuclear weapons. My history teacher had the idea that if you put an empty box in a high-security centre, and claim that it has the power to destroy the whole world, and that if any nation sent spies etc to try to find out about it, the weapon will immediately destroy itself and the whole world. How many people would dare to look?
M.A.D., Mutually Assured Destruction, the Detente(spel?), the belief that nuclear weapons save the world and prevent major wars. Rubbish! We have had many minor conflicts since the second world war, and was a single nuclear bomb dropped? If the nations of the world had such weapons as to destroy the world three times over, why have none ever been deployed? Eventually tyrants and dictators will not be afraid of such devices, and the world will be plunged into that which it was, almost continual war. Yes, destroy all nuclear missiles, conventional wars are bad enough. And while your at it, destroy B's and C's as well.
Then destroy bombs, guns crossbows, tanks etc There will probably still be wars after all the weapons havd disappeared, for a human can be a weapon, if properly trained. So to destroy the ultimate weapon, you would have to destroy the whole human race and what does that lead us on to? Atomic weapons!
Let us leave all this weapon technology at tanks. And pray for peace.
