Here is an excellent analysis of the progress on agreements on what happens after the UN mandate for US troops runs out this year in Iraq. It appears to boil down to the US demanding occupation (no constraints on troop actions and full immunity from the law for US troops and contractors) versus sovereignty for Iraq with a timetable for US withdrawal. It also appears the agreement will be "just between two guys" ie Bush and Maliki because the congresses in both countries will refuse to approve the agreement. And how legal is that (not!) and do they really care?
