Webb may have been against getting into Iraq; but judging from his appearance on This Week he does not support withdrawal. Via Think Progress:
In terms of the aftermath, no one in a responsible position in government is saying that we should pull the plug in Iraq and have a precipitous withdrawal. What we’re trying to do is to say, eventually we have to withdraw from Iraq, we have to draw down our troops. Even the military realities of the surge, which have upswung the cycles of deployment, are going to mandate that we reduce our troops, and eventually leave.
We’re not going to have stability in that region until the American troops are out of Iraq. We have to do it in a way that brings in the other countries around the region, allows us to focus on international terrorism, and does not destabilize the region. But it must be done.
In other words, we have to stay until we have those Production Sharing Agreements in place.
