In US schools, the history of the Middle East is largely glossed over. To say I've dabbled a little is like saying a flea jumped on a leaf and was lost at sea somewhere in the Pacific Ocean.
To us, the message is largely that Christianity is good and "we" can do no wrong.
We certainly didn't cover US "interference" in Iran, for example, much less what happened to the Jewish people after the Holocaust. "We won WWII: Party on!"
As you well point out, there is so much more complexity to everything going on over there: it isn't just about what happened in the last 70 some-odd years, either.
This is way above my pay grade.
