If you're running a successful administration, then you're loyal to people who are basically good who make a mistake. And that seems to be essential for any organization. And it should be essential if this were a normal administration, rather than a fiefdom, where everybody simply tries to give Donald Trump a good headline every day.

The things that make them similar - their machismo, their expansionary braggadocio - is going to turn them I think into bitter and dangerous enemies. We will look back on this moment where we thought Vladimir Putin and Donald Trump were sort of close as a moment of bitter irony, when they get into a schoolyard display against each other, amping up each other's worst tendencies and putting the two countries in some sort of scary position.

We have an international system. We all profit from it. Trade profits from it. Peace. We can travel around the world because of it. And part of that system is certain ideas, the certain ideas you can't invade other countries for no reason. You can't commit genocide. You can't - rogue regimes can't have nuclear weapons, and you can't gas your own people.

Most poverty and suffering - whether in a country, a family or a person - flows from disorganization. A stable social order is an artificial accomplishment, the result of an accumulation of habits, hectoring, moral stricture and physical coercion. Once order is dissolved, it takes hard measures to restore it

If I were Donald Trump, I would definitely not pick Mitt Romney because it's very easy for Mitt Romney to have have a separate foreign policy operatus in the State Department that would run a dissenting foreign policy from the White House foreign policy. There, I think the populist America-first foreign policy of Donald Trump does run against a potential rival.

The idea that a big country is going to go out and send troops into some country to take their resources, and then the rest of the world is going to somehow trust us is just a ridiculous notion.

Trump has picked the more extreme versions of all Republicans so far, the more aggressive. And I think the thing to watch out for is, I could totally paint a scenario where Trump runs an authoritarian regime. I can totally paint a scenario where he has no control over his own government.
