I'm going to talk to you about power in this 21st century. And basically, what I'd like to tell you is that power is changing, and there are two types of changes I want to discuss. One is power transition, which is change of power amongst states. And there the simple version of the message is it's moving from West to East. The other is power diffusion, the way power is moving from all states West or East to non-state actors. Those two things are the huge shifts of power in our century. And I want to tell you about them each separately and then how they interact and why, in the end, there may be some good news.
