James Clapper: “Well, I would hope it'd be the ladder, although I don't have -- you know, based on the history thus far, I'm not real…”

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.

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 this reflects Russian insecurity. And it's almost like, Putin needs a rhetorical security blanket, of making threats, like this.

A stark reminder that the terrorist threat to this country hasn't gone away. We cannot take our eyes off this ball.
