People do discuss Japanese wartime atrocities.  Frequently.<p>It would have been a bad example for the above post, though, because people actually opposed Japan's conduct in Manchuria <i>contemporaneously</i> (whereas China's conduct in the status quo, the Soviet Union's conduct for its entire existence, and the first few years of German fascism were/are dealt with limp-wristedly when they were not actively applauded).<p>For example, the United States hit Japan with a steel/oil embargo after Japanese refused to withdraw from Manchuria, which was the proximate cause of Japan deciding to go to war with the United States.  (Funny little historical note: the US didn't actually intend the embargo to be a total embargo.  When it was conceived in Washington it was as a temporary cutback to force Japan to the negotiating table.  A minor bureaucrat misfiled something, though, and the planned periodic review never happened, which turned it into a total embargo.  "Whoops.")<p>As an aside, essentially none of Japan's present economic prosperity is owed to wealth stolen from China.  Most of that got very comprehensively burned, along with the rest of the country.  Japan was pretty desperately poor postwar prior to the US' Korean war buildup, which they largely sourced in Japan, re-laying the industrial base which ignited the Period of High Economic Growth (高度成長期) that brought Japan from "substantially poorer than Mexico" to "really freaking rich".<p>Apologies for the lecture.
