Given the Islamic law as far as i know - Saddam hussain deserved what he got in end i.e. life for life. But the issues are different & they cannot be sidelined one-Dictatorship was an internal issue of Iraq & should have been best left to its citizen to find out its solution. Second - Wepons of mass destruction - the ground of waging the war are yet to be discoverd & President Bush & his allies are yet to come-out with a satisfactory answer not only to the world community but also to their own countrymen.
Third - the most important of all - the reason given for Saddam's execution - is killing 148 countrymen. Does the world not know how many innocents belonging to either Iraq or USA + Allies have been killed in the war -a war which was supposed to have comeout with WMD and Saddam hussain, not to mention the financial, emotional and other indirect losses. No sensible person on this earth can conclude or justify the WAR. So where does world stand today!!!! A president responsible for the loss of inumerable life & yet a sitting president vrs A president responsible for 148 lives and hense a death reward.
