"A carefully researched treatment of the highs and lows of U.S.-Japan-Korea trilateral policy coordination. . . . It merits reading by both scholars and practitioners of East Asian security."--William J. Perry, Former Secretary of Defense and Special Advisor to the President on North Korea Policy "Cha's book is a meticulously documented yet readable account of the tensions and interactions between America's tow allies in Northeast Asia in recent decades. It adds significantly to accessible knowledge of a difficult but increasingly important relationship."--Don Oberdorfer, author of The Two Koreas: A Contmporary History
