There will be boots on the ground if there's to be any hope of success in the strategy.

There's a lot of books out there about how you lead change in business, but I've certainly not seen any... on how you do that in public institutions.

I didn't think this whole business with Director James Comey was handled well. So there are sort of day-to-day aspects of the operation that I think are really troublesome. And I know that there are a lot of people in the country who have lots of issues with decisions that Donald Trump has making on the domestic side.

It's clear the relationship between China and North Korea has hardly ever been worse. Kim Jong-un has never been to Beijing in his leadership. The Chinese press are saying some amazingly negative things about the north, and about Kim Jong-un. So - so they are weighing in, and they are bringing greater pressure. Whether it will be enough I think remains to be seen.

No policy has proved more successful in making friends for the United States, during the cold war and since, than educating students from abroad at our colleges and universities.

My one concern is that Hu Jintao may overestimate how much power China has in Pyongyang. They have - they do have influence, and they do have companies, and they do have economic relationships that could make life much more difficult in the north. Their balancing act is, "How much worse can we make it in the north without creating that which scares us more than anything, which is a collapse in the north." And then what happens to all those nuclear weapons. So they're going to work very hard to avoid that.

I don't know General Michael Flynn well, but it's hard for me to believe anybody would allow themselves to be blackmailed by the Russians because they didn't tell the full story or didn't tell the truth to the vice president of the United States who works 50 feet down the hall.
