Iraq under Sadam was ruled by a strong Sunni government (though far from just) ruling the Shiite majority and were in full control. Now Iraq is ruled by majority Shiite ruling minority Sunni but with little control. Shiite Iraqi calculations were that once America removes Sadam, they will rule Iraq and will link to their guardians in Tehran.
Despite being Arabs, Iraqis Shiite loyalty is more towards the Iranian Shiite spiritual leaders. They forget two things. One, they are Arabs, two, Shiism originated in Iraq, stolen by the Persians over time.
For more than one billion Sunni Muslims, Maliki died the same day he executed Sadam. Maliki has insulted all Muslims in the timing he chose to execute Sadam. Sadam was executed on the dawn of the holiest day of the year for all Muslims.
This is the day of sacrifice, where Prophet Ibraham saw in a dream that he is killing his son with a knife. In the morning Ibraham spoke to his son about it. The son said to his father: if this is God will, do it. God interfered and requested to save the life of the son with that of a sheep. This holy day became a symbol of saving human blood for animal blood.
For Maliki, who could have delayed or advanced the execution a couple of days, but intentionally did not do that, he insulted all Muslims. But more so Sunni Muslims, by killing a Sunni on the holiest day of the year. Maliki is not ignorant, and he chose the day for just that reason. America shares the blame for not knowing how big the insult would be.
For Sunni Muslims, Maliki is a burned card that can never be used again, and the longer he stays the more difficult for Iraqis. I personally think that once he is out of government, he will go into hiding considering the massive scale of his humiliation to fellow Sunni Muslims across the world.
Where do we go from here? Shiite Iraqis realized that their outnumbering the Sunnis, which they were betting on, didn't work. The numbers make a difference in the polls but they do not bring peace and security. After Sadam, Shiite ruled Sunnis in Iraq with hate, discrimination and revenge (far from Nelson Mandela's forgive and forget).
It seems Shiite Iraqis needed some more time and some more bloodshed to wake up from their dream of Iran-dominated Iraq and full control of the Sunnis. Until they realize it is justice and secular rule, not the numbers, that bring peace, there will be more trouble ahead.
