You are a sectarian dude no wonder you are in such delusion
First of all that bastard so called Saddam had no benefits to Sunnis as you have already imagined by yourself. He was killing Sunni revolutionaries of Kurds too. How come Sunnis were also his victims? He destroyed Iraq's future by attacking Iran, in fact he gained the power with a silent coup inside Ba'ath party, the party that it's true leadership had introduced Israel as it's main enemy. I can claim all of Ba'athis and their true anti Israeli feelings were destroyed by that bastard. Instead of attacking Israel, he tried to invade Iran, why???
There are plenty of evidence that he was killing Shias and Sunnis in Iraq, the revolutionary forces. Exclude that punk so called Barzani from Muslim Kurds, he is not popular among Kurds not to mention. Saddam was CIA agent inside the body of Ba'ath party.
Shias are in majority in Iraq so their vote would be more however Iraq is not a sectarian country. PMU the popular forces of Iraqi nation has almost 5 thousand of Sunni fighters who are already liberating Sunni cities from ISIS and other terrorists. President of Iraq was a Sunni Kurd, Jalal Talibani who had good relations with Iran. I just wonder, you are enemy or a Jahil sectarian dude?!!!!
