My uncle was captured in Italy in WWII and told he me years ago that the Gestapo conducted a short arm inspection of the POWs and executed the ones that were circumcised, presumably Jews. My Swedish-Irish (100 percent American) uncle survived.
With regard to the POWs on the Al Jizeera tape on has to ask, "why were only some of the prisoners executed?" The pants were obviously pulled down. It is known that the Iraqi TV has told the Iraqi people that the are being invaded by Americans and Israelis.
If the Red Cross can get to the surviving POWs they must follow this line of investigation. Why is it that the American public can't be shown violence and sex without Hollywood getting the proceeds?
