The Real War Crime for which the Nuking of Hiroshima and Nagasaki was Condign Retribution was, of course, the Japanese Military Rape of Nanking, in 1937....

There are no official records of the number of Chinese civilians murdered--babies bayoneted--by the Japanese in this protracted atrocity, which began on the 13th of December, 1937, but most best-estimates put it at something between 200 and 300 thousand--which is (I would just like to point out) the same number, more or less, as the combined civilian dead in the atomic bombings of Hiroshima and Nagasaki.  So let's forget about these as the (Divine) Retribution for the bombing of Pearl Harbor--however sneaky that may have been.  What always matters in the murder of civilians is the number of civilians slain, not the sneakiness or forthrightness with which it was done.  And there ought to be, every year, public memorial demonstrations in Nanking (now, I think, NanJing), staged by the so-called government of China, and the surviving citizens of Nanking, just to show that you can't do something so horrible on so vast a scale without its being forever remembered and infinitely abhorred.
