This is not true, and it's unfair to label Iraqis as being stupid. After 30 years of being brutally oppressed by Saddam Hussein, the entire country has "battered wife syndrome" where they believe they are entirely impotent to do anything on their own behalf. This is not their fault. The entire country has been brutalized for 30 years.
Look at how Elizabeth Smart felt completely trapped after just a few hours/days/weeks/months in her kidnapper's hands. And then think how it must be for Iraqis who's entire country has been kidnapped and brutalized for 30 years. Very few people in Iraq know any other way of life than to be completely, totally, submissive and without free will.
Blaming Iraqis for not standing up to Saddam & Co is like blaming the battered wife for not standing up to her battering husband. Who's fault is it that wives (Iraqis) are brutalized, their husbands (Saddam) or the wives (Iraqi people) themselves??
I have compassion for the Iraqi people. I have NO compassion for the terrorists, Saddam-loyalists, and die-hard Ba'athists who want to continue oppressing the Iraqi people via terrorist and guerilla warfare tactics. But I know the Iraqi people cannot yet stand up for themselves against these wannabe oppressors. It will take time, and the help and guidance from other Free people of the world. And this is why our troops are still dying every day over there - so that one day the Iraqi people will be free from the oppressors.
Notice how I also noted that that sort of thinking was typical of "leftist thought."
