"We're invading to defend the people against a brutal oppressor" is the argument always used. By Americans in WWII, by Russia today. Some of the worst war crimes and genocides in history have been committed systematically by the armies you've so far mentioned: Germany, America and Russia. These atrocities have been ordered from the highest leadership in these nations. Modern war is hell and there are no good guys left when it's over. If you believe that, they are recruiting volunteers.
Americans did not happened to be the invading brutal oppressor commiting genocide in WWII. Their standard behavior during that time was was remarkably better then behavior of Soviet army which was better then behavior of German army.
Your position is that joining Jewish resistance is as bad as joining SS and both are totally the same as being member of an American army.
