If this is what bothers you so much, what stops you from doing exactly the same ? I am not sure they sell Irranian flags in Wallmart, but you can sure find one or make one yourself. Then get some beer; invite Bill.K and maybe few more friends who share your anger, and knock your self up burning it!
You can also get some kick out of using large poster of Ahmadinejad as darts target. Maybe do some home made fireworks that resemble nukes over Tehran as well. It can be therapeutic.
Get the anger out of your system! Just make sure you don't burn your and/or neighbour's house.

Relax man :)
