The War on Terrorism in Korea

Korea absorbed more american bombs in three years then the us. Dropped in all of world war two. Truman, his secretary of state, dean atchison and the joint chiefs fumbled for a way out of war in k Korea that did not mean starting a world with china. And so collaboration with our former axis emy was in order. This meant that people like japanese officer shiroishi, a bio chemical weapons expert were quietly brought under american protection rather than prosecuted for their crime. Were guys like eshe and his particular line of work useful?
