Iraq can escape its cycle of violence which mostly caused by people internally. Whatever is going on Iraq is because of terrorists and leaders like Sudam husain. Iraq lacks politics and administration. Iraq can become good nation if they correct their government and actually start developing as nation. And I think normal people living there would favor it because they want to see their nation develop as well.
The entire mid east region is known for being a hotbed of violence and war. This area has experienced this problems for thousands of years and while the overall violence ebbs and flows throughout history, there is no reason to expect the tensions to disappear anytime soon. Unfortunately, population and an array of different beliefs have caused a lot of problems here.
