Especially interesting is that the Iraqi victory was celebrated by waving the Iraqi flag in Kurdistan. The Iraqi team had Kurds, Shia Arabs and Sunni Arabs. And the Yugoslav national team had a successful World Cup in 1990, making it to the quarterfinals... and broke up anyway. Here's a fascinating video on that era - haven't finished watching it myself. Most of it is in Serbo-Croat but it's subtitled in French with occasional English. But really the atmosphere is what you pick up on - Croats chanting "We love Croatia, let's go massacre some Serbs" and Serbs singing songs about massacring Croats. Yet 3 or 4 years earlier, these fans were all cheering for the same team.
And a hilarious (black humor) quote passed on from a friend of mine:
Ellen: Holy crap, Iraq won the Asian cup!
Andy: I know! You know why? Because we didn't try to help them with it.
Update: New Yorker in DC also has a post on the victory.
