Regrettably, nothing is mentioned about post-war adjudication of the Japanese involved in this atrocity.
Also on this date (1941), 3,500 Jewish men were executed by the invading Germans (Operation Barbarossa) in the Soviet-occupied half of Poland at the Khotyn Castle, Zloczow, Poland. Part of the ‘Final Solution’ planning, the Einsatzgruppe SS units accompanied 2nd wave troops for the explicit purpose of killing all Jews within their individual areas of operations. By fall of 1941, it became obvious to the Germans that these tactics were problematical and were soon switched to a general roundup and transporting to the various kill areas.
A good point...
Japanese scientists did some terrible experiments, on humans, in Manchuria during the World War 2...After the war, US did not prosecute most of them because they handed over the data to Americans...
