Dr. Ahn puts a new spin on the historical origins of Korea’s relationship with America distinctively through the lens of an individual contribution as he delves into the vital role of U.S. General William M. Dye in the early Korean modernization of the late 19th century. The large volume is an exceptionally rare, original, and fact-based exploration of how US-Korea comradeship has evolved for over 130 years into the U.S.-ROK security alliance as it exists today. The masterpiece is an outcome of, among others, back-breaking reviews of old diplomatic documents. Still, it is more interesting than a novel; written in a fascinating style, it holds the reader’s interest from start to finish.
