I am trying to teach you that Al Queda had declared Iraq to be the central front in the war on terrorism with the US. That they would run the US out of that country. To do this this the incited sectarian violence against the shias so that they would attack the sunnis.
This plan was laid out by Al Zawahiri and carried out by him.
The majority of mass suicide bombing in Iraq were done by Al Queda. After the bombing of the Golden Mosque exactly what Al Queda wanted to happen happened, shia began killing sunni.
At that time Obama and the democrats wanted to surrender, pushed for surrender, declared the war lost and voted many times to surrender. Only the republicans were willing to see it through and now we have a victory in Iraq versus a surrender to Al Queda.
