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.

I have sort of a visceral aversion to the prominence of the either active duty, in the case of General McMaster, or retired general officers filling political, civilian positions.

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.

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.

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?

What I said was, ‘the NSA does not voyeuristically pore through U.S. citizens’ e-mails.’ I stand by that.

I think, as a professional courtesy, when the president asks you to dinner, you go.
