I think talking's important. I think aspirations are critical.

We need to be more precise in how we talk about these issues. People around the word follow our presidential campaigns so closely, trying to get hints about what we will do.

At least I have a plan to fight ISIS.

Well, you know, once again, Donald [Trump] is implying that he didn't support the invasion of Iraq. I said it was a mistake.

We also have to intensify our air strikes against ISIS and eventually support our Arab and Kurdish partners to be able to actually take out ISIS in Raqqa, end their claim of being a Caliphate.

We need some leverage with the Russians, because they are not going to come to the negotiating table for a diplomatic resolution, unless there is some leverage over them.

I have pretty thick skin. I've been in the arena a long time, and that means that I am not going to get down with [Donald Trump] and go insult for insult.
