In the lead-up to the anniversary of the Hiroshima and Nagasaki bombings, philosopher John Pepple at I Want a New Left has been emphasizing atrocities committed by the Japanese in World War 2. His motive for this is that he feels that many people today tend to blame America for everything while glossing over much more horrific acts done by other countries. My motive for linking to him is that people often focus on the evils the Nazis committed, but many are unaware of the horrors perpetrated by the Japanese. Pepple went over The Bataan Death March, The Rape of Nanking, The Manila Massacre, Korean Comfort Women, and Medical Experiments on Live Prisoners.
