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.

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.

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.

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

We call upon the nuclear-weapon states to immediately cease their plans to further invest in modernizing and extending the life span of their nuclear weapons and related facilities.

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.

Nobody thinks identically on Syria. But we share the same view with Russia that the future of the personalities in Syria will be determined by the people of Syria and not by people outside Syria.
