Peace on Earth: Spec-fic

There was peace on earth, and there had been for one hundred years. It wasn't that people didn't still have their impulses to anger, the proprietary urges that make countries want to fight off what they see as the enemy. It wasn't that there weren't scarce resources that might have made some want to war. It wasn't that the ideological hatred of others wasn't still a popular game, especially in politics. No. It was quite simple, really. Whenever somebody announced a war, moved towards war, or tried to gather weapons or armies for the idea of war, they vanished. Gone. Poof. As if they'd never existed. The major heads of state in the big five countries had gone through six replacements in as many days until they figured it out. Because naturally the first thing one thinks is, "Somebody kidnapped my president, and I will declare war on them."

Inspiration: "It Came Upon A Midnight Clear" sung by Patti LaBelle and the Bluebells
Story Potential: High, at least as a setting.
Notes: Interesting. I like it. Not the evil peace, not the mindcontrol peace, but something else. Maybe aliens, maybe conspiracy, maybe force of the collective will to live once the weapons got up to World War strength.
