Historically and culturally, Arabs has always considered Iraq as the heart of the muslim civilization. In fact the old muslim empire reached its ultimate power under the Abbasi Caliphate which was headquartered in Iraq and particularly in Baghdad. Iraq is also “geographically” located at the center of the Middle East and any change in Iraq will certainly affects the whole region. Based on this I am saying that the defeat of terrorism in Iraq will crush the world wide islamic terrorism for a many decades if not centuries because they will not have the power to wage another major war and their ideology will be greatly defeated. As I said before I strongly believe that the defeat of terrorism in Iraq will lead to the collapse of the Iranian and Syrian regimes, these two terrorists regime cannot possibly go on when they have been defeated in Iraq.
You may consider it wishful thinking, and you want me to show you the proof. I cannot show an “exact proof” but I am writing to you about what I think will happen based on my knowledge of the area.
In response to 371, you are correct in many aspects. Where I think you're missing the point is the heart of the Arab world is not being faught. It's quite different. And now it's more a civil confrontation than anything else. Where the region has a homogenous population (mostly Kurd or Shite) the area is largely, but always peaceful. It's where there is a blend of Sunni's Shites and Kurds (although less Kurdish involvement) is where the problems are. It's Sectarian. Not the fight you're portraying.
