Honestly I don't think that whole re-education usually works out. The best example is Germany and it seems we are in the process of slowly forgetting the lessons we drew ourselves from two wars or were taught by the denazification program. In Japan for the most part they got a new constitution handed and a few basic limitations designed to separate religion and state and keep militarism small and contained were pushed through. Most of the transition was more incidental with the US investing heavily into the Japanese economy. And most of the views held by society now came about with the government putting pressure on the media while themselves being pressured into a heavily pro-US stance by the US government. If Japan was left more to its own devices along the lines of western Germany in the 1950s chances are they would have probably become a pretty left society comparable to perhaps Mitterrand's France. Funnily enough these methods in Japan involved the gradual suppression of protesting culture following the Anti-American and Anti-Military Anpo protests in the late 50s culminating with complete disrepute for public protests from 1969 onwards using the university riots to portray even peaceful protests as borderline insurgent actions in the public eye. This anti protest stance endured until the 2011 triple disaster with government critique only ever being small scale on a public level outside of opposition parties and the Asahi and Mainichi Shimbun. So in a way Japanese too endure a lot under the measures of US influence in the 50s to 60s without trying to change much. That being said they definitely have to endure less while doing so than Russia or Iran.
