I think Trump's presidency represents a completely different model than what we're used to. And I think to your point, yes, he is a great communicator, you know? He uses Twitter to great effect. I just wish he could stick more to the truth, because it's a very effective way of communicating directly with the American people.

If we - particularly, if we peremptorily attack North Korea - that without deliberation, that North Korea will reflexively unleash all the rocketry and artillery - which they're pretty good at, by the way - on Seoul, and do as they vowed many times, to convert Seoul into a sea of fire. So, if we do something like this, this will have cataclysmic results.

First Russians objective was - as I said earlier - to sow discord, discontent, disruption. And their next objective was - because of the very strong personal animus that Putin himself had for both Clintons, both President Clinton and Secretary Clinton - and he particularly held her responsible for what he felt was an attempted color revolution in 2011 to attempt to overturn him. So, he had very strong hatred - personal hatred - towards her, and that kind of led him to - if I'm opposed to her, who am I going to favor?

I don't think the intelligence community itself institutionally is losing its focus; it will continue to do its job; continue to be vigilant on all issues that are besetting us. I think the greater danger is just the preoccupation of the policy community, and how much attention they pay to what the intelligence community is telling them.

There's nobody that wants the president to be successful more than I.

The president sets the tone. He creates the atmosphere, and that can be enlightened, progressive, or it can be intimidating, depending on what the president's agenda is. I think the other dimension of this that I worry about is impacts overseas with friends and allies, many of whom are very, very concerned about America's position in the world and whether or not it's going to continue its leadership, which has been the prevalent condition since World War II.

I've expressed concern about the assaults on our institutions, both from external sources - meaning the Russians - and internal sources. And I think this will be a real test of the resilience of our system and its pillars.
