When I said, "Let Iran handle the Shittes and Syria can control the Sunnis," I meant that Iran (being predominately Shiite) and Syria (being predominately Sunni) should take more responsibility for the radical members of their sect. The ties are already there. It would make more sense for Iran and Syria (jointly) to maintain control in Iraq after the withdrawl of U.S. forces into Kurdistan.

If they cannot maintain order in Iraq, then Iraq will have to be divided but I don't think thats the ultimate solution. I do think that the U.S. would have to have a military presence in a separate Kurdistan to protect the Kurds from any fall-out in Iraq.

There is no perfect solution to the problem of how to withdraw but our best chances of saving U.S. troops from being slautered is to retreat into Kurdistan.
