So there are two separate tracks. One track is for the Syrian government and the opposition that is interested in a peaceful future of Syria to come together for national unity, for the political process. At the same time, it is a requirement for everybody to stop supporting the extremist groups, to stop allowing them safe passage, to stop allowing them to receive weapons, to stop allowing them to receive financial assistance, and to come together in actually fighting them.

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.

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.

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

We consider ISIS and extremism to be a threat to all of us in the region. . . . Our position is that we help the legitimate governments in the region that have representation in the United Nations. We help the Iraqi government on their request through advisers; we help the Syrian government on their request to help with advisers to fight extremists. . . . So it's both lawful and legitimate.
