Isn't Iran worse than Iraq? The regime is worse than Saddam. They bascially preach "Death to America" everyday.
The regime in Iran is far worse than Saddam, but the situation in Iran is far different. Iran has a long history of fighting for democracy. There are consistent pro-Democracy demonstrations in Iran - 70% of the population are under 30 - polls put the regimes support at about 15% and the younger generation are pro-American. A revolt works much better when dealing with Iran.
