Can we blame the man who started the war in Iraq for the violence and loss of life and suffering in Iraq?

Almost 180 people died in Iraq today due to the ongoing violence there. Many more unfortunate people are suffering with unexplainable pain due to broken limbs and body injuries and so on. The trauma for their even more unfortunate parents, spouses, children and near and dear are beyond any words can explain. How many people died in this war and the sectarian violence triggered by this war? No one really knows !!! The man who started this unjustified war is still addressing his great nation with his typical wicked smile and asking for more fund to keep the war going. It may sound bit odd when considering the fact that 3,000 + young men and women from his own country had to sacrifice their precious lives for a war that they don't know why they have got into. The question is: Whom to blame for this war? The man who started it by misleading a great nation or can we p the buck to so and so person who gave the wrong information on the existence of WMD in Iraq?
