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're not going to radicalize them. We never have. Your allies have radicalized people who visited.

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.
