'Despite very good scholarship on various aspects of the US-Korea alliance, we do not have a good single-volume account that covers the entire history. Uk Heo and Terrence Roehrig fill this gap. They also show how the rapid growth and democratization of junior partners both expands the possibilities for cooperation and opens up recurrent conflicts. Needless to say, timely and relevant.'
