Yeah pretty much, because there is nothing else that compares in that way. Climate change is long and drawn out, meteors and disasters are acts of nature.

There is nothing else so swiftly and completely destructive that is entirely driven by humans and their choice as to whether they should destroy or not.

That's the thing about nuclear war, unlike all those other things, it really comes down to a few humans deciding not to do it. That's what makes it more terrifying than those other ones.
