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.

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.

This visa-waiver thing is absurd. Has anybody in the West been targeted by any Iranian national, anybody of Iranian origin, or anyone travelling to Iran? Whereas many people have been targeted by the nationals of your allies, people visiting your allies, and people transiting the territory of, again, your allies. So you're looking at the wrong address.

Iran is a powerful country. Iran is a big country with a large population, natural resources, human resources. But we are a country that is content with its size, content with its geography. We have not engaged in any military adventures in the past 250 years. We don't see any of this as Iran trying to dominate this region. We see some people panicking in our region and we believe there is no need to panic. We are prepared to work with all our neighbors to ensure the security and prosperity of our region.

The Persian Gulf is our lifeline ... We will respect international navigation, for us, freedom of navigation in the Persian Gulf is a must.

People have been fed misinformation. The fact is that the fighting that is going on on the ground in Syria is with Al Qaeda, with Jabhat al Nusra, with Daesh. The pockets, small pockets, of other groups are usually surrounded by these various extremist groups. . . . Once they stop fighting, there is nothing for the Syrian government to hit other than the terrorist organizations.
