The historian Chalmers Johnson has written that: It may be pointless to try to establish which World War Two Axis aggressor, Germany or Japan, was the more brutal to the peoples it victimised. The Germans killed six million Jews and 20 million Russians [i.e. Soviet citizens]; the Japanese slaughtered as many as 30 million Filipinos, Malays, Vietnamese, Cambodians, Indonesians and Burmese, at least 23million of them ethnic Chinese. Both nations looted the countries they conquered on a monumental scale, though Japan plundered more, over a longer period, than the Nazis. Both conquerors enslaved millions and exploited them as forced labourers — and, in the case of the Japanese, as [forced] prostitutes for front-line troops. If you were a Nazi prisoner of war from Britain, America, Australia, New Zealand or Canada (but not Russia) you faced a 4% chance of not surviving the war; [by comparison] the death rate for Allied POWs held by the Japanese was nearly 30%.
R. J. Rummel, a professor of political science at the University of Hawaii, states that between 1937 and 1945, the Japanese military murdered from nearly 3,000,000 to over 10,000,000 people, most probably 6,000,000 Chinese, Indonesians, Koreans, Filipinos, and Indochinese, among others, including Western prisoners of war. This democide was due to a morally bankrupt political and military strategy, military expediency and custom, and national culture." According to Rummel, in China alone, during 1937-45, approximately 3.9 million Chinese were killed, mostly civilians, as a direct result of the Japanese operations and 10.2 millions in the course of the war.
