General David Petraeus, the 3rd ranking US policymaker on Iraq (behind Bush and Cheney) just said --
unchecked, these [Iranian-backed] Special Groups pose the greatest threat to the long-term viability of Iraq.
This is the war that began about WMD and then became about al-Qaeda. Neither was in Iraq when the war began, and the latter is now, apparently, no longer a threat.
UPDATE: There's a new catchphrase from Ryan Crocker -- "post-kinetic development". Kinetic was one of those military words that George Bush thinks is really cool.
FINAL UPDATE: The exact Petraeus statement was --
Unchecked, the Special Groups pose the greatest long-term threat to the viability of a democratic Iraq.
Someone else notices the shift.
