Under Suddam the peace which was created, although costly, had given way to a society that while repressed under a militarist regime, was still growing economically and socially. This peace was shattered when the government and many of the people decided it was prudent to invade. Now, the region has be brought to Civil War, disorder and death. Nothing has been made better, and if the US army does not have the will to finish what it has started, then it should not put its nose into the affairs of anyone else.
Before "democracy" can be created, there must be peace. While I am not a fan of the saying "Arms keep peace" it is too late to do anything else.
And I do not say this only at America, the Israeli war with Lebonon is one of the great autrocities against mankind. The killing of so many, destroying so many lives and resigning millions to poverty! There is no justification for this.
