After the warheads have gone off, people die, melt, vaporise or whatever and after that, some mutant tribes will be formed as only 1% of the world human popualtion survived! They will have minor skirmishes between eachother for years and years. The nuclear dust and radiation will dissipate and the mutated human tribes will die from the new natural habitat. Nature shall rule supreme again and forests and grassy fields will grow upon the once radiated fields of dirt. Man shall be gone from this earth for all eternity and the circle starts again only not homo sapiens sapiens will evolve into the capacity to think, but it will be the allmighty species of rabbit (although that isn't a name for the species i think) and the rabbits will overrun the world and kill all others who oppose them just like man once did. Not even the wolves and bears will survive against the "Allmighty Rabbits"!!!!!! Dum-dum dum-dummmmmmmmm.....
Believe me, it has been scientifically proven that this isn't just a wild theory!!!! And, i wouldn't be surprised if one of the rabbits would sacrifice himself to press the button of the first nuke!!!!!!!!! dum-dum-dum-dummmmmmm...."Be aware of the of the ones who lurk in the forests with long ears, for they will be the doom of man"!!!!!!! That is a quote that Kong-Fuzi, Jesus and Mohammed have stated.
