For real; nuclear war wouldn't destroy whole Earth or even humans, but USA and Russia would be quite blasted (if those are the only participants), though probably for example Siberia and Alaska wouldn't be so much blasted.
But maybe Russia would blast whole Europe too, who knows, that was the plan before. Still, Earth is large.
To sum it up: keep your asshole games in your ass. No need to blast big part of Earth because of two fucking countries. Two fucking countries; there are about 200 countries in total.
