Authorities aren’t sure yet whether the video of the murder actually depicts Pfc. Matt Maupin, but in any case this just underscores the fact that the turnover of sovereignty in Iraq is not going to change a thing. The jihadists are fighting to establish an Islamic state, and they aren’t going to be any more favorably disposed toward what they perceive as a U.S. client state than they have been toward the U.S. military presence there. That unrest will continue, and that the new Iraqi government will face fierce challenges and may not survive, are the only certainties in Iraq today.
