The Pentagon survey found that less than half the troops in Iraq thought Iraqi civilians should be treated with dignity and respect. More than a third believed that torture was acceptable if it helped save the life of a fellow soldier or if it helped get information about the insurgents. About 10% of those surveyed said they had actually mistreated Iraqi civilians by hitting or kicking them, or had damaged their property when it was not necessary to do so.
Whether we should have gone in the first place is a well worn topic. This however is a reason why we shouldn’t be there anymore. This is how you create ill-will, enemies, and ultimately… terrorists.
