Obama's Iraq withdrawal plan may prove difficult

Martha Raddatz reports that U.S. commanders in Iraq "warn of security dangers," and see a "logistical nightmare" in Obama's Iraq withdrawal plan:

Whatever nuance Barack Obama is now adding to his Iraq withdrawal strategy, the core plan on his Web site is as plain as day: Obama would "immediately begin to remove our troops from Iraq. He will remove one to two combat brigades each month, and have all of our combat brigades out of Iraq within 16 months."

It is a plan that, no doubt, helped Obama get his party's nomination, but one that may prove difficult if he is elected president.

Watch her video report:

Didn't Obama check with anyone before he proposed his "one to two combat brigades each month" withdrawal plan?

A higher quality version of the video report is available at ABC News, but you will have to suffer through an ad.
