We ought to be doing much more in North America. We are on the cusp of an energy revolution. And we do need to be doing more at home. The biggest national security threats facing the United States right now are not in the Middle East. They are domestic.

I think it was going to be hard to work with Russians on Syria. There is some potential overlap between the U.S. and Russia in that the Russians don't want to see the Syria situation unravel to a point where they have to escalate their own involvement. But at the moment, I don't see the U.S. and Russia on the same page in Syria. Russia seems much more interested in consolidating government control over liberated areas. It seems to me that the U.S. and Russia are proving they can disagree for independent reasons in any number of theaters.

Hillary Clinton is pretty much what we would call a foreign-policy realist, someone who thinks the purpose of American foreign policy should be to adjust the foreign policies of other countries, work closely with traditional allies in Europe and Asia towards that end.

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.

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.
