Yup, and he's not the only one. More and more middle east experts, academics, military men, politicians are saying the same thing - we need to bring down the regime in Iran.
Of course a Regime change is preferable. But that isn't happening. It hasn't happened in 30 years. How much time do we waste, waiting for a Regime change? The Mullahs and their puppets in government are getting closer everyday. How much time do we still have? I think we have run out of time. And there will be no big revolt in Iran. It will be business as usual, under the Mullahs. And they will obtain nuke technology, very shortly. And No One will stop them. And this will do nothing but create more states with more nukes. On and on it will go. If Iran is not stopped. It will lead to unprecedented numbers of countries with nuclear weapons, or those trying to obtain them.
