President George W. Bush has struck an aggressive new tone in his clash with Congress over Iraq, telling lawmakers they had no business trying to manage the war, portraying the conflict as a showdown with Al Qaeda and warning that any move toward withdrawal now would risk "mass killings on a horrific scale."

As opposed to staying in Iraq, which will guarantee that mass killings continue on a horrific scale. Almost a year ago, a study placed the death toll at 650,000 Iraqis. As usual, conservatives reacted by denying the validity of the study, without actually explaining what part of the methodology was incorrect.

In a nutshell: that figure was probably an overestimate, but not by a huge amount. And we've had, oh, almost 10 months of continuous war and bloodshed since then. Yup. We don't want to pull out now and risk mass killing when we can stay and guarantee mass killing!
