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.

Tehran believes it's none of our business or anybody else's to decide the future of personalities in other countries.

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.

You cannot have security at the expense of the insecurity of others.

If anything caused ISIS, it was the 2003 U.S. invasion of Iraq.

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.

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.
