So in short, the question we have tonight is, how do we understand this mega-change, which I believe to be the biggest change for the first half of the 21st century? It'll affect so many things. It will go to the absolute core. It's happening quietly. It's happening persistently. It's happening in some senses under the radar, as we are all preoccupied with what's going in Ukraine, what's going on in the Middle East, what's going on with ISIS, what's going on with ISIL, what's happening with the future of our economies. This is a slow and quiet revolution. And with a mega-change comes also a mega-challenge, and the mega-challenge is this: Can these two great countries, China and the United States -- China, the Middle Kingdom, and the United States, Měiguó -- which in Chinese, by the way, means "the beautiful country." Think about that -- that's the name that China has given this country for more than a hundred years. Whether these two great civilizations, these two great countries, can in fact carve out a common future for themselves and for the world? In short, can we carve out a future which is peaceful and mutually prosperous, or are we looking at a great challenge of war or peace? And I have 15 minutes to work through war or peace, which is a little less time than they gave this guy to write a book called "War and Peace.
