It is almost a certainty that a civilization-ending nuclear world war will occur within the lifetimes of today's young people.
This war will be a war fought by the "villages" (nations) who embrace sexual perversion (Queers) against the "villages" who have retained the sexual moral rules that developed in the period when 25,000 successive families solved the problem of life to produce you. We have those rules because they work. You in the decadent West are not the wo'th generation to rebel against those rules. Many have preceded you, and they were all destroyed. We know that from the observed universality of sexual moral rules across human cultures. So your destruction is a certainty, for it is the pattern of human evolution.
The war will be triggered by some event that ignites some kinetic conflict over some random issue, of which there are several candidates (e.g. resource competition, nuclear terrorism, the failure of a nuclear state). But, once started, the combustion will be fanned by the irreconcilable conflict between the "Western world" and the "Muslim world". With modern, worldwide, instantaneous communication, Western decadence simply cannot be tolerated by the Muslim world, which it will inexorably corrupt and destroy. With modern, nuclear, weapons, this conflict will explode out of control and destroy all of civilization, both that in the West, and that in the Muslim world.
