He is yet another bad guy who was supported by the US. Who saved his ass from jail? The US of course. He lobbied hard, provided fake intel and got them to invade Iraq. Now that he's realising that he's not so popular with Iraqis he's trying to become friends with Iran in order to get supports from the Shia. There are rumors he provided Iran with some US secrets.
In short, he's a thief who, thanks to lobbies and pressure groups, managed to get the US to bail him out from jail, give him a huge monthly salary and put him in a leadership position in Iraq. Now that things aren't going exactly as planned, he's turning on them. Big surprise from someone who was supposed to be rotting in jail somewhere in Jordan
