The USA is pretty scary. More nukes and a bigger army than anybody else, and willing to elect war-hungry fundamentalist Christians into the highest positions of power. Eek!

But as far as starting World War III, I predict it will happen somewhere in Asia. No one country will be to blame, but the concentration of hotspots (Korea, Taiwan, India/Pakistan, Iran, Israel, Indonesia) aren't very promising for world stability.

The places least likely to be affected by WW3, I predict, will be South America and Africa. I just don't see any country having any beef with them, so when all hell breaks loose you guys can come find me in Argentina or something.
