The co-author of this book, Mr. Hideaki Kase, is a right-wing Japanese revisionist who openly glorifies Japan's war crime during WWII and calls the horrific Nanking Massacre a fabrication. He also calls the "Comfort Women", women who were captured by the Japanese during WWII and were forced to be sex slaves for the Japanese Army, prostitutes. Not only Mr. Kase has little credibility in reviewing Japan's role during WWII, but also he is one of voice for the Nazi Japan.
