Uhhh, exactly what does this "world peace" you're talking about look like? Preventing any other nuclear powers from rising by, what, nuking them? What if we can't tell that they're building it until it's done, which is exactly what we did during WWII? Not like there's any shortage of incentive to hide it. And nukes don't kill everyone. What do you expect the survivors of these attacks to think and do? Clearly in this vision of "world peace", we'd have to be regularly attacking other countries with nuclear weapons, and at some point, somebody else would succeed in building an arsenal of them and have every reason to immediately attack us with them. If that's what world peace looks like, you can keep it. I'd say what we have now is much closer to world peace than what you propose. All of the big industrial countries have lots of nuclear weapons, and nobody uses them, so they're all too terrified to attack each other. The only wars we have are major powers occasionally invading small, weak countries, rightly or wrongly, and either dominating them or being chased out by insurgents. Even if every one of those invasions was horribly, horribly wrong, it beats the hell out of having another WWII every generation, or everyone constantly nuking each other.
