 You know, I think basically you have to break it down into the chronic and the acute. You know, there are things that clearly are longer-term problems that people are concerned about, Russia, China, Iran, and those are problems that are going to be around for a while, that any administration is going to have to deal with, ISIL, those are things that are ongoing. Then there are the sort of acute things that could pop up early in the administration. I think one that got a lot of attention was North Korea, in part because of Kim Jong-un's threats, promises, if you want, about developing an ICBM, testing more nuclear weapons, but also because the South Korean political system is melting down and the South Korean presidents being impeached, so the timing coinciding with the inauguration of a new U.S. president is potentially quite propitious for a very bad event to happen there.
