JAMES BAKER, FMR. SECRETARY OF STATE: Tom, I think the only thing that offers much hope is if we could pull together in a true international coalition of countries, we should go 100% all out to defeat the radicalism and the terrorism that's arisen in the Middle East. But you're not going to get it done unless you bring the rest of the world together behind it.
TOM BROKAW: And what is the role of our Arab allies, like Saudi Arabia?
JAMES BAKER: Well, we have to have our Arab allies involved in the fight. But it can't be on a sectarian basis. I mean, the truth of the matter is, that Iran is very, very much opposed to what ISIS is doing. I wouldn't be at all surprised if Iran was not helping us quietly deal with some of this.
