James Clapper: “The sanctions are having an impact in Iran. No question they've had huge impact on their economy.”

Well, no, it doesn't. And the fact that none of this makes sense, but most acutely, I think, nuclear-related information.

Ties with Tehran offer some regional governments a means of staking an independent position on Iran, thereby mitigating its isolation while also attempting to extract Iranian financial aid and investment for economic and social projects.

I think it has more to do with the psychology of Putin, and Russia. And he needs to assure his own people, Parliamentarians, he was talking to, and for that matter, himself, that Russia is still a great power.

Well, Anderson, that's exactly right. And this is what this whole issue boils down to, is will to fight.
