Regardless of how you feel about this, it is PURELY a political campaign move.
If it is, then the democrats have fully adopted the Biden-Kerry Doctrine that no war involving US troops is worth winning
And, as with everything this administration does, it is an extremely stupid move. If it works, it will have been largely forgotten come election time, but if the Iraq goes sour, it will be a millstone round Obozo's neck during the campaign.
I actually do not agree with that at all. Believe it or not I actually support this, since it sounds like the troops would not be given immunity.
So, hell yes, they should all be pulled out if this is the case.
