You cannot be effective if those who work for you are not. So building their effectiveness ought to be a priority.

Globalisation thus implies that sovereignty...needs to become weaker.

The reason I called the president Donald Trump a disrupter is that he came into office 70 years after World War II, 25-plus years after the end of the Cold War. Like any president, he didn't come into office with a blank slate - he entered with an enormous inheritance of relationships with institutions, policies and the like. And in my view he is much too quick to pull the U.S. out of various institutions and various agreements, and he's been much too quick to question the value of allies and alliances.

Jerusalem is a holy site for Jews, Muslims, and Christians. Israelis and Palestinians both lay claim to it as their capital. Jerusalem is the most sensitive of all the issues that need to be addressed in order to achieve a peace agreement between Israelis and Palestinians. But Donald Trump determined an important aspect of the United States' position towards Jerusalem before any agreement. Most of the rest of the world feels that it ought not to be dealt with first, that it ought not to be dealt with separately, and that it ought not to be dealt with unilaterally.

If the president Donald Trump had connected the Jerusalem question to some other positions, linking it to Israeli and Palestinian behavior or putting the Jerusalem statement in a larger context of U.S. policy, it could have potentially advanced the peace process. But I don't see how singling it out might help.

Well, we ought to make clear to everybody that the next Korean War, if one were ever to happen, is going to be the last Korean War because it's going to end with a unified peninsula, and it's go to be under Seoul, not Pyongyang.

If there's any country that has the capacity not to control North Korea, but to influence North Korea, it's still China. The Chinese always say they have very little influence. They have more than they say they do. We should put pressure on them to do it and there's finally, we're seeing the first signs of a little bit of Chinese disaffection. At some point they're getting tired of the antics of this country. This is a dangerous ally for China to have. And the more Chinese can pressure them and put the economic screws on them, the better it will be for everybody.
