Excerpt:Â I am constantly amazed that in the ongoing debate over the Iraq war the central question that ought to drive our decision is seldom considered. We focus on the difficulties in staying the course and achieving the mission, but rarely discuss the consequences of abandoning it. This is sheer insanity.Following Gen. David Petraeus' congressional testimony and based on his recommendations, President Bush outlined his plan to reduce troop levels in Iraq to their pre-surge levels by next summer. Quite predictably, Democrats immediately proclaimed their opposition to the plan. In the face of this impressive report and Gen. Petraeus' stellar reputation for competence and good character, I can think of only a few reasons Democrats would remain in obstruction mode.
