The Iranians know what they need to do in order to become a responsible member of the international community and in order to become a good neighbor, and it's really up to them to change their behavior.

Daesh is attacking us. Their leader, Abu Bakr al-Baghdadi, wants to destroy the Saudi state. These people are criminals. They're psychopaths.

We support any deal that denies Iran nuclear weapons, that has a continuous and robust inspection mechanism and that has snap-back provisions in case Iran violates the agreement. Our concern is that Iran will use the income it receives as a result of the lifting of the nuclear sanctions in order to fund its nefarious activities in the region.

There is nothing to encourage. The Iranians should just stay away from us.

Should the political process not work, there is always the other approach.

We can't do both. If you want us to lead, don't criticize us. And if you want us to play a supporting role, then tell us who is going to lead.

The Middle East has gone through periods of turmoil before. In the 1950s and 1960s, there were revolutions. When monarchies were collapsing in a number of countries, we had radicals and we had Nasserism. Today it's a little bit more complicated.
