Army analysts foresee bleak road ahead in Iraq

UNDATED A couple of top Army analysts say the U-S shouldn't expect so much for Iraq's future.

Andrew Terrill and Conrad Crane advise against setting a schedule to withdraw of U-S troops. But a new study from the Army War College experts says an American presence in Iraq probably can't go on more than three more years.

Terrill and Crane also think it's increasingly unlikely that coalition forces will "crush" the insurgency before withdrawing.

They also believe it's "no longer clear" the U-S will be able to train an Iraqi military that can secure the country.

Terrill and Crane say the U-S may have to "scale back" expectations for a future Iraq and accept a relatively stable but undemocratic state.
