I think a little more gambling on the world stage could dramatically improve things. For instance, what if Chirac, Putin, et al. - instead of criticising Bush for not having offered compelling evidence for the existence of the WMD he claims Iraq has - said "Okay, we BET you One Hundred Billion Dollars that you can't show us the WMD after you take over Iraq! We'll send in our troops, go in as Allies, and if, after we take out Saddam, we find the WMD then we were wrong, and we owe ya' the $100,000,000,000. If not, then you owe us $100,000,000,000."
That would be too cool. I wonder what would happen. There's just no accountability when a world leader doesn't have to put his money where his mouth is.
