I wish i was as hopeful as you Hoori, but i really don't see that happening. I just see the sectarian conflict getting worse and worse. Shiites feel they have been opressed in their own country for a long time now, perhaps rightfully so, but that has made them extremely hostile towards sunni's, sunni's feel the same animosity towards shiites, the hate you see in them is really scary. How exactly the new Iraqi government is going to put a lid on this, i don't know. It doesn't look promising at all. Oh and i agree that sacrifices have to be made for democracy and freedom to prevail, history tells us as much. I don't think American invasion is the solution though. The choice has become between the stability yet extremely restricting conditions of a dictatorship, or the chaos and killings that will erupt because of the sectarian conflict. Its a hard choice to make, but i think i'd go for the former.
Iraq is going to pay a very expensive price for the strong sectarian feelings of its people though.
