The whole "Circle of Gobal Funding" is something that unfortunately needs to stay. I would, however, venture to go as far as saying 25% of everything we give goes to our enemies (both directly and indirectly). I don't have any proof to back up that claim, but just a guess like most on here do. Even at that staggering percentage, I'd hate to see what would happen without our monetary physical support. Believe it or not, we're controlling the world's stability, even if it isn't our initial funds that is backing it. I'd give society (as we know it) would completely change within a year.
Just off the top of my head, Israel would be attacked by everyone and their mother, Russia would take back the USSR territories (and possibly more), China would expand, South Korea would cease to be thanks to the North, Africa's ethnic cleansing would go ape shit (no pun intended), Venezuela and Cuba would be loading up from Russia, The Balkins (all those counties that were once Yugoslavia- Bosnia, Kosovo, Croatia, Macedonia, Serbia, etc) would be hammering away at eachother again if Russia wasn't already stomping them a new mudhole, India and Pakistan would be popping off at each other while Afghanistan hits Pakistan from behind... I won't even get into the random terroristic activities.
Need I go on?
