I have absolutely no idea what the people advocating for "one last push" in Iraq, with an influence of however many additional troops can be temporarily "surged" into Baghdad are thinking. One last push for what? A higher troop concentration in some particular area might get whatever disfavored elements are around to lie low or head elsewhere for a while, but it's not as if we're going to have the mapower to go house-by-house through Iraq and scrub the country of weapons. The various armed factions in Iraq are far too embedded, socially and politically, in the fabric of Iraqi society. This just seems like a desperation pundit play to avoid admitting that the "left" position -- we should leave Iraq -- is, in fact, the correct one.
