Who needs a wartime nuclear exchange when you have peaceful countries nuking the gamma rays out of their own sovereign territories - now that the environmental theme is rather popular, the following video by Isao Hashimoto shows all the nuclear "tests" conducted by the world in the period between 1945 and 1998.
Based on public data, the world's peaceful countries have already nuked themselves at least 2,054 times, with the US nuking the state of Nevada and its immediate neighbors about one thousand times. And keep in mind - the fallout does not just miraculously "disappear." Feel free to consider that next time you look at bargain properties on the strip.
Anyway, as Idealist asks, "How would your life be different if you were taught in school a small nuclear war already took place?" One thing is certain - Congress would be stunned and appalled, and the disgraced CEO of Nukes R Us, Inc., who previously gave trillions in campaign contributions to every Congressional critter, would be facing a very unpleasant and theatrically televised day.
