I think the most important challenge that remains is this mentality in Washington that sanctions have been an asset, and some people want to find even an excuse to keep them or an excuse to reintroduce them. I don't know whether they've looked at the record of how sanctions actually produce exactly the opposite of what they wanted to produce.

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.

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.

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.

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

It is important for everybody to insure that the process will go on, that the ceasefire will hold. Of course, there is no ceasefire against Daesh [the Islamic State], Jabhat al Nusra, and Al Qaeda.
