Is It Time to Change Course in Iraq after All?

It's been another bloody day in Iraq with at least 24 civilians killed in a suicide bombing in Mosul; 73 Americans have been killed already this month, which is on the way to becoming the worst month for US casualties in more than two years. US commanders said today that violence in Baghdad has increased since 12,000 joint US-Iraqi troops were deployed in August and that Operation Together Forward will have to be revised. Increasing numbers of Republicans say it's time for a change.  We get an update from Baghdad on increased violence and US impatience with Prime Minister Nouri al-Maliki, and hear from Iraq's Ambassador to the UN about his government's plans to disarm sectarian militias and stop the death squads. Should Syria and Iran be asked to help restore order? Is it time for a phased withdrawal?
