I don't know about [Rex] Tillerson, but I do know that John Bolton doesn't get it. He still believes in regime change. He's still a big cheerleader for the Iraq war. He's promoted a nuclear attack by Israel on Iran. He wants to do regime change in Iran. So, I think John Bolton is so far out of it and has such a naive understanding of the world. If he were to be the assistant or the undersecretary for Tillerson, I'm an out automatic no on Bolton.
