Built upon the highly successful volume One Hundred Years of Korean-American Relations, 1882-1982, this book describes Korea’s importance to the United States and the development of the current relationship. The ramifications of this relationship are evident by the facts that South Korea now constitutes America’s seventh largest trading partner and 37,000 American troops remain stationed there on alert. North Korea, however, continues to harbor a deep resentment of the United States and its southern neighbor and maintains the fifth largest standing army in the world, situated just north of the world’s most fortified demarcation line at the 38th parallel.

When the major powers sent troops to the Korean peninsula in June of 1950, it supposedly marked the start of one of the last century's bloodiest conflicts. In volume 1, Allan Millett, however, reveals that the Korean War actually began with partisan clashes two years earlier and had roots in the political history of Korea under Japanese rule, 1910-1945. In volume 2, he shifts his focus to the twelve-month period from North Korea's invasion of South Korea on June 25, 1950, through the end of June 1951 -- the most active phase of the internationalized "Korean War."
