Does the prospect of nuclear disaster still frighten anyone these days?

[abaris]

I fear that two possibilities are all too likely.
One, that some terrorist gets his hands on a nuke and uses it on a city.
Two, a regime is run by a madman and decides to nuke an enemy.

Neither seems unlikely enough.

Doesn't seem that likely either. It's not enough to obtain a nuke, you also need a carrier system. Now if we're talking dirty bomb, it's a different matter. That's certainly possible.

And we already have a nuclear regime run by a madman. North Korea. You'd need a suicidal madman for something dangerous to happen. And even then it's highly unlikely that a single suicidal madman can simply push the button without anyone else not wanting to die stopping him.
