"As regards the Islamic republic [of Iran], they want to frighten the regime and then disarm it, the consequence of which will be the erosion of the regime's legitimacy inside the country."
Before they would lose power they would kill thousands in Iran and possibly in the world. They are already killing our boys in Iraq through their support of the "insurgents/terrorists". They will ratchet it up and give aid to those who would attack on our soil.
I believe because of our situation in the world right now the Iranians are going to have to do a revolution like our country started with. We are too engaged to give them much aide right now.
The people of Iran are waiting for a clear message from our government. We haven't provided it yet.
I suggest reading this excellent report to understand why.
