As an Iraqi, I do ask this question to myself a lot, what the world opinion on modern Iraq. It changed a lot especially after ISIS war, but people here generally don't value the change that much due to high unemployment rates, drought, and bossy militias.
I'll just throw mine in to help confirm some of the general consensus coming from the states. Before 9/11, nothing really. A few brief mentions in history class etc, our education is horrible about human history but shoves American history down your throat. During the wars? Absolutely fucking horrific that any country is just allowed to attack an area like that. Every time I heard about some new operation I thought about how my family (if they were in that situation) would be huddle in the corner of a room just hoping to survive the night. Something that would make me want to lash out at anything because of the danger to my family, I never got why ANYONE thought this would "stop the terrorizing" by making more radicalized citizens.
After and currently, I'm completely blown away by the historical and cultural context of Iraq. In school there was never an emphasis on how important that country was to the civilization that we have now. Every documentary or book I read that touches on ancient history includes that area. I think if it was better taught in schools, the general consensus would've been more honorable towards finding a solution that worked for both countries.
