We need clarity about our relationship with the rest of the international community. How much of the burden is our country going to have to assume? What we do not want to see is, without a forthright national dialogue, tens of billions of dollars and tens of thousands of troops continue to pour into Afghanistan without knowing what we hope to accomplish.

The time is now for a major national debate on Afghanistan. That hasn't happened. I think the scariest thing that can happen is that just, very quietly, we get sucked into a war that is a never-ending process. This is an issue about which we need a lot more clarity and a lot more debate.
