no, right is martin indyk, vice president, director foreign policy program at brookings. my boss, all of our bosses. ken lieberthal, director of the center, senior fellow of foreign policy, global economy and development at brookings. and from the far right is michael o'hanlon, senior fellow and where he specialized in u.s. defense strategy. all of these gentlemen are highly experienced. they have been practitioners as well as scholars, and bring a wealth of understanding i think, and particularly in dealing with an issue like this, trying to evaluate a president foreign policy, bring a lot of historical and comparative understanding. i think it's very easy to look at a presidency either in isolation our own in comparison to the last presidency. but, of course, there was a broader historical context in which we have to look at the obama administration, and this book really does put into that context. so i thought i would just ask, try to start a discussion here, talk about some of the issues that are raised and then i'm simply open it up to you for your questions as well.
