You don't want to put too much emphasis on one response over two days of hearings, but when Sen. John Warner (R-VA) asked Gen. Petraeus a short time ago if victory in Iraq would make America safer, Petraeus hedged before saying, "I don't know." Perhaps it was just a moment of uncharacteristic befuddlement for the general, but if the answer to that question isn't a resounding yes, then, even on the Bush Administration's own terms, it's time to start loading up the troop carriers in Kuwait and bring our people home.

Late Update: In follow-up questioning from Sen. Evan Bayh (D-IN), Petraeus backtracked from his "I don't know" to Sen. Warner.
