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.

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.

We have lots of challenges around the world, and I have no doubt the intelligence community will continue to watch them, monitor them, and report on them. The issue is, with all of our other distractions here in Washington, particularly, will the appropriate attention be paid to each one of these issues?

When I visited North Korea in November 2014, is that Kim Jong-un is not merely the head of state of the DPRK - the Democratic People's Republic of Korea, North Korea - he's also their deity. So, when you insult him as the head of state, you're also insulting the deity, which of course the regime plays to a fare-thee-well to the domestic audience there.

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.

Trump is very skillful at identifying - even if he can't quite get it clear, or precisely describe it - but that's what he wants to do, is always have something to use against people, even if it's distorted.

President Trump has the advantage of being surrounded by an excellent cadre of advisors. Kim Jong-un doesn't have any advisors that are going to give him objective counsel. He's surrounded by medal-bedecked sycophants, who dutifully follow him around like puppy dogs with their notebooks open, ascribing his every utterance, and pushing back against the great leader is not a way to get ahead.
