The worst kind of job to have is a job with lots of responsibility and very little power.

The madman theory can work, but it only works if it's strategic. And I think one of the problems that President Trump faces is people don't really know how much strategy is here and how much is he just sort of talking off the top of his head. And I think North Korea is a really classic case of a potentially insoluble problem, a problem that you have to manage.

If you really want to change the Trump administration, you have to change the guy at the top. And that's not happening anytime soon. But, again, where I do think where you will see some movement is on this economic side, where I suspect, for example, this is a victory for China, because Trump was - I mean, Bannon was the hawk on China trade.

Politically, Donald Trump doesn't seem to care much about what he says. He gauges the effect. Sometimes, in the middle of a speech, he will change his direction if the audience doesn't like him.

Hope is different from optimism. Hope is a tough virtue, not a psychological predisposition. Hope insists on taking facts and reason into account and still insisting that improvement ... is always a real possibility.

The New York Times had a headline on its website - Trump Turning To Ultra Wealthy To Steer Economic Policy. This doesn't sound very populist to me. Today's commerce secretary, the names being talked about for treasury secretary, I think there will be populist talk but maybe no populist action.

It sure looks like [Vladimir] Putin did this [hack DNS site]. And we all need to take this seriously.
