It’s the concept of a world war.

It’d be regional, for sure. I don’t think Israel is going to pull the US into it, nor Iran pull Russia (mostly because they don’t even have the power to fight a war on their own border). Egypt, Saudi Arabia, and the rest are going to try to stay out of it as much as they can, but still contribute a little material support. I don’t think it’s going to be a global conflict.

The start of WW3

Yep.

We’re due.

As a species that got to be number 1, we have nothing left to express our dominating nature on except ourselves. You don’t just evolve out of that in a couple hundred years—you gotta have a nature that is highly successful at doing what it does best deeply instilled. It seems every now and then we have to let it out. It’s like masturbating to weird porn. We’re ashamed after, say we’ll never do it again, but over time the nature needs exercise.

It’s just what we are. It’s in our nature to kill each other if there’s nothing left to dominate. We need it. The best you can do is reject it and try be a better person every day, and not hate yourself if that species number 1 nature comes out at times. Evolution is incredibly slow.

Edit: Sorry if no one wanted to hear that. And it’s obviously a personal opinion.
