Suppose Egypt invaded Quebec?
If Quebec were a dictatorship & Egypt invaded, putting in their own government & occupying the major cities, then had to put down guerilla fighters. This included Americans who decided to join in the fight. Evidence of whatever-Quebed-was-supposed-to-have-done never comes to light. Egyptian forces torture their POWs. The death toll rises into the tens of thousands, with no end in sight. Power & water for most of Quebec is out. Some Egyptians start calling for obliterating the Christiano-Fascists that threaten Islamic culture. Then Egypt begins demanding the IRA disarm or maybe they'll invade Northern Ireland, demanding to know why the Pope hasn't condemned Christiano-Fascist terrorists.
Does this scenario help explain how the people of the Middle East might feel about US troops in Iraq?
Just a note--no one has yet answered the question. Not one. Regardless of what anyone believes or doesn't believe about American policies in the Middle East, does this scenario help you see how the average person-on-the-street might look upon events?
