Ok lets back up and make this clear. Yes I said the US is trying to unite the people in Iraq. But I'm saying that is a front, i.e. that is not the real goal and the goal is to further the divisions in the region. To be crystal clear,
The US is on the surface showing the world an image that they want a united Iraq, but the means they choose to do that are specifically choose to lead to further division of the Iraqi people. I'm sorry if this has not been clear thus far. As far as to what policy should be in place? I have no clue, I wouldn't even advance one cause I don't think I know enough about the entire conflict to presume that I could come up with a workable solution. All I can say is that based upon what I see, this solution is meant to accomplish other goals.
On the point about the Kurds, IMO, they are doing the same thing as the US. They are positioning themselves to carry out their real intentions. Their current actions are simply a means of getting others to buy a farce of their supposed support of a democratic Iraqi government. Read this article about a potential goal of the Kurds:

The thing about current new reports about the Kurds is that your only getting commentation on what they are doing right now. There is very little on there on what their leaders are actually thinking or planning. Sure, you can mark it up to speculation, but the chances of this are very high in my opinion given the history of the region and the unchanging goals of the Kurdish people.
