I think it is important to do one's history research here; may i suggest we read William Shirer's book Berlin Diaries and the stuff on 1937 - 1939 in berlin.
Then we would be capable to assess that teacher's transgression, especially if we compare Hitler's propaganda machine as detailed by Shirer to the news leading up to Iraq.
Likewise with reports and documents of Nazi warfare and that in Iraq. Simple source research = reading and thinking. makes for much better arguments than gang ho forward march type dialog.
Just a thought ...
Hallo truth!
