So there are two separate tracks. One track is for the Syrian government and the opposition that is interested in a peaceful future of Syria to come together for national unity, for the political process. At the same time, it is a requirement for everybody to stop supporting the extremist groups, to stop allowing them safe passage, to stop allowing them to receive weapons, to stop allowing them to receive financial assistance, and to come together in actually fighting them.

We try to coordinate regularly with Russia, as well as with others - except for the United States - on what is happening in the region. And we're open to discussing with everybody the situation in Syria, because we believe it's a common threat.

Nobody thinks identically on Syria. But we share the same view with Russia that the future of the personalities in Syria will be determined by the people of Syria and not by people outside Syria.

You know where the people who killed people in San Bernardino came from. You know where people who did 9/11 came from. You know where the people who did Paris came from, where they transited, where they went. None of them even set foot in Iran. So why are you punishing people who are visiting Iran for that? . . . We're not going to radicalize them. We never have. Your allies have radicalized people who visited.

The United States wanted to send its trained rebel groups to Syria to fight ISIS. Out of twenty-five hundred rebels they had trained, only seventy accepted to go to Syria to fight ISIS. Everybody else wanted to go to Syria to fight the government. So you've got to wake up and smell the coffee. . . . The rebel groups have not fired a shot against ISIS.

I think we are making an assumption that that is the outcome of the negotiations. I think President Assad will be prepared to accept whatever the outcome of the intra-Syrian dialogue and the decision of the Syrian people is. But people are trying to decide and determine the outcome of the negotiation before even we agree to start the negotiations.

We've never declared war on anybody. We [Iran] defended ourselves against wars that were imposed on us. We have no desire to engage in confrontation with anybody.
