The House today set a deadline: US troops home from Iraq by the end of August next year. Some liberals who want to end the war now went along, even though the deadline is part of a spending bill to support the troops in the meantime. Is it political posturing or the start of something big? In addition to soldiers, there’s a staggering quantity of arms and equipment. Would a pull-out be a logistical nightmare? Is it all moot anyway, because the Army’s running out of deployable troops? What would a pull-out look like, especially one conducted under the pressure of a binding deadline? We hear from journalists, peace activists, defense and security experts.
