Discussion with people who are obsessed about a particular view is ultimately unproductive.
Do you think it's better to be obsessed with the truth or to be obsessed with maintaining a delusion of gigantic proportions, JW?
The average person engaged in discussion is always willing to concede some points and attempt to find some common ground.
Even the average US prosecutor/politician/military guy in the WWII war crimes trials were happy to find common ground. Where it was shown that the US committed the same war crimes, the common ground became, "Well, you can go free in exchange for us not discussing that issue".
Where there was valuable information to be garnered by the US, say, from ex-Nazis or from the leaders and personnel of Unit 731, the same "common ground" was found.
American grant of immunity
After Imperial Japan surrendered to the Allies in 1945, Douglas MacArthur became the Supreme Commander of the Allied Powers, rebuilding Japan during the Allied occupation. MacArthur secretly granted immunity to the physicians of Unit 731, including their leader, in exchange for providing America, but not the other wartime allies, with their research on biological warfare.
Unit 731 was responsible for some of the most notorious war crimes carried out by Japanese personnel.
American occupation authorities monitored the activities of former unit members, including reading and censoring their mail. The U.S. believed that the research data was valuable. The U.S. did not want other nations, particularly the Soviet Union, to acquire data on biological weapons.
What "common ground" might you be seeking, JWWandel?
