I'm fine with taking things calmly. But what your advocating is the ostrich approach to problems.

That's just being blind about the problems. Nuclear war is all one of the biggest existential threats to civilization. It didn't end with the cold war.

Think of all the close calls we've had. Now look forward 100 years, what's the odds it happens? 1000 years? 10000?

We're our own worst enemy and our civilization is the biggest threat to civilization.
