There must never be a third world war, it would imperil human civilization itself. There can never even be a total war between two major powers anymore. Our weapons are just too awful.

Unfortunately I'm not sure that our politicians self-preservation instincts, strong as they may be, trump their egos (sorry for the pun.)

I'm of the belief that a world war today, which immediately launched all existing weapons to cause as much damage as possible, probably wouldn't wipe out the human race.

As soon as you launch that many weapons, and kill such a high percentage of people, you eliminate the possibility of manufacturing new weapons, so the war would be instantly over.

And I believe that despite others simulations to the contrary, there will be small groups of people who will stay underground for years, surviving on tinned etc. food. After 5-10 years, radiation levels will still very high, but most dust will have settled, and the skies clear enough to start to grow crops and rebuild.

Humans, as well as many other creatures, will become more radiation hardened over generations, and given the bountiful supplies of tech and resources left over from our civilization, will be able to quickly repopulate the world.

I agree fully, it's absurd to think of wiping out the human race. There is basically no disaster that would leave the Earth intact but wipe us out. We're the most adaptable species the world has ever known and we're everywhere.

I said civilization would collapse in a dire nuclear war scenario, which is not the same thing. Advanced civilization itself may actually be quite fragile - we see glimmers of that fragility now and again when government / order / utilities break down for prolonged periods.

You don't need survival instincts when you're insulated, and, in many cases, easily isolated (see: elite class buying bunkers).
