Who is the enemy?

Joe Lieberman:

"Some of these opponents of the war are now turning their harshest criticism on our allies in Iraq instead of our enemies."

And on Military progress:

Indeed, while it is true there is no pure "military" solution to the violence in Iraq, it is worth remembering that neither is there any pure "political" solution. Al Qaeda in Iraq and other irreconcilable extremists must be defeated and destroyed in order for Iraq to be stable and free, and for the United States to be safe. Al Qaeda is not mass murdering hundreds of Iraqi civilians in suicide bombings because the Iraqi government hasn't made enough progress toward political reconciliation, but because al Qaeda is determined to destroy any hope of political reconciliation.

Update: Markos himself (predictably) attacks Lieberman, calls him "stupid."
