It is not so much as that people remember history is that it is selectively remembered. Not that the Middle East is the only place this happens, but it seems peculiarly acute there.
Perhaps it seems that way because you're fixated on the place. Look at Europe. Look at Japan. Look at the US.
Remember Islam is ALWAYS and has ALWAYS BEEN the victim. No aggressive actions from those that profess the religion has ever occurred.
One of those things you can't catch anybody saying so you have to say it yourself. If you have some litany of aggressive Muslim offenses (and given the prominence of
jihad in the religion it's necessarily a long one) before the current situation in Iraq can be raised, please consider it read.
The local reaction to the US invasion, conquest and occupation of Iraq is that it's no different from the British Empire's invasion, conquest and occupation in 1941. That was in response to a republican coup against the Hashemite monarchy installed by the British under the Mandate.
When the Great War Allies tried to incite the natives of the Eastern Ottoman Empire they had a less than lukewarm response. The locals were well aware of European imperialism's career over the previous century. They'd be replacing an Ottoman rule, which they understood and could work around, for an unknown European imperial rule.
Those that did respond, Lawrence's converts generally, were promised that this would not happen. They were lied to. As was Lawrence.
I suppose it wasn't until the 1960s (not that long ago) before much of the US could be geniunely self-critical about its history, but I really think that a little of that would do wonders in the Middle East.
What is it that the people of Iraq should be concentrating, self-critically, on in your view? The failure of the mosque-based opposition to topple Saddam themselves? The weakness of the Communist opposition because of their atheism? What is it that you, not living in a very active war-zone with a wrecked economy and little effective policing, think they should be shriving themselves of?
