I really think that nuclear weapons may have saved the world from extreme misery. Without nukes, I would not be surprised if we had had another world war (dang that grammar grates) if MAD had not come into existence. And if you look at the phenomenal advancement of technology during WWII, it's not hard to see that we would quickly learn to kill people even more effectively in a hypothetical WWIII. If you look at pictures of Tokyo after the fire bombing, it's pretty much indistinguishable from Hiroshima. Vast expanses of nothing but ash. I think WWII cost Russia alone something like 20 million dead. And that's without massive strategic airstrikes on their cities. In fact, I wonder if the world could have taken third world war within a 60 year timespan. Not that we would go back to the Dark Ages, but we may have been set back considerably. Heck, I may have just persuaded myself that nukes were the savior of humanity. How's that for messed up.
