What's really fun is that conventional weapons can protect you from a crazy aggressor if you're strong enough, but nuclear weapons may not. They only act as a deterrent, so they require your enemy to believe you'll use them, believe that they can't destroy all of them before you use them, and understand the horrible consequences of retaliation.

I get the impression that Trump is pretty negative on nuclear weapons and I don't think he'd do something that could provoke nuclear retaliation. But I doubt he'll be our last mad king. I think the odds are pretty high of at least a small nuclear war within my lifetime. Even if the US keeps it together, proliferation means much higher odds of some idiot leader somewhere pressing the Button.
