The two most capable nation state adversaries in the cyber domain are clearly Russia and, of course, China. And I do think Russia poses a huge threat in the way they have used the cyber domain. That, to me, by the way, is the big issue here, is Russian interference in our political process, in our election process. And that is an egregious act by them. And they will continue to do that and I think more aggressively than they have in the past. And I think it's something Americans, all American citizens need to be aware of.

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.

We're talking about nuclear war with North Korea. We're talking about Russia. Does it feel like the world has shifted? Are we all just in Donald Trump's reality show now?

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.

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.
