Can Burger King and McDonalds Bring World Peace?
I'm going to go out on a limb, and say...no.
Being that it's going to be held (assuming it happens at all) for just one day in just one location, I tend to think that this proposed event might not have the firepower to bring the world together for hand-holding.
Maybe if we could get all the belligerents in the world to start thinking Arby's instead of armies...
