A story of espionage that could have changed the course of history and saved thousands of American and British lives - and millions of Asian lives. Before the Second World War, Korean-American Kilsoo Haan repeatedly warned the United States about the Japanese attack and accurately supplied every conceivable detail as relayed to him by Korean agents: midget submarines as well as aircraft at Pearl Harbor, and a joint Chinese-Japanese attack - Operation Ichi-Go - against the American and Chinese Nationalist forces, which drove through Chiang Kai-shek's much larger army. He was ignored. The story of American influence in Korea and dealings with Japan provides a little-known new perspective on the Pacific War and remains a factor today in international politics. Author John Koster explains the tragic and bloody entangled histories of Japan, China and Korea that form the backdrop to this extraordinary story.
