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.

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.

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

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.

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.

The nuclear program is not the only issue dividing Iran and the US. Iran's role in the region is also creating conflicts. For example, you support the Shiite Houthi militias in Yemen whereas the US is on the side of the coalition led by Saudi Arabia.

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.
