It’s only useful to ask, what wisdom have you learned from your misjudgments that will help you going forward?

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.

Britain is blessed with a functioning political culture. It is dominated by people who live in London and who have often known each other since prep school. This makes it gossipy and often incestuous.

You have to have a plan, or else you're just creating a recipe for chaos.

Donald Trump's got to do some big changes, because what he was voted on. But when you think about how to do it, it would take massive expertise, which his people, believe me, do not have.

When you're running for president, you're a guest in the living room for four years. And if people don't think you're going to be around the living room as a pleasant experience, they're not going to vote for you even if they agree with you.
