Why not Iran?

Iran might be the only muslim popluated country who hasn't protested to the war at all. There has been no major (or even minor) street protest against the war.
There are two reasons: First, nobody has suffered from Saddam's regime more than Iranians. The eight-year war which Iraq started in 1980 costed lives of 600,000 Iranians, who were mostly young volenteers who joined the war to help the weakened former-Royal army because of the revolution. Iraq used chemical weapons on Iranian forces as many as 40 times in the last years of war.
Secondly, people are so tired and fed-up with the current religious regime that they sometimes say they'd like to be liberated by the Western countries.
