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.

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.

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.

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.

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's military hardware is less than a fraction of that of any of the countries in this region.
