What about asking what's the probability that nuclear-powered nation gets an autocratic leader who can decide on his own whether to launch the first strike? I think the current situation most strikingly points to the dangers autocratic governments pose to the whole planet. If people of a nation could vote on whether to start nuclear war I think they would vote no. But a crazy dictator? Not so sure. It should be the law everywhere: No nuclear first strikes. But that can only work if rule of law is the rule. The other great concern is misinformation and ability to keep most of the nation misguided enough to support a war. There should be international law to prevent spread of misinformation that can cause or lengthen wars.
