What’s interesting about the first and third Indy movies, which have the Nazis as the big bad, is that they have what could be interpreted as subtle digs against certain groups that collaborated with them. In the first movie, you have the French archaeologist which could represent the Vichy, and the Arab informant which could represent some leadership in the Arab world who at times also collaborated (e.g. Grand Mufti of Jerusalem). In the third movie, you had the American business man that collaborated with the Nazis representing the American corporations that had trade relations with them, and those in the US that were sympathetic like Ford/Lindbergh, etc.
