I think Petreus should consider flipping himself.  The media really didn't make that big of a deal about the Biden question at the time, but I thought that was the seminal moment of the hearings.  In no way can we let the Taliban and Al Qaeda gain even a comftorable foothold in Afghanistan.

From the sounds of things, the Taliban has had its own "surge" and our troop presence there might not be able to hold them back with as much efficiency.  Petreus/Bush/McCain haven't answered the question Obama raised about where will we find the troops to send into Afghanistan.  I think Obama can make a compelling argument that Iraq is the best place to find such troops.
