What is victory? What is the strategic objective? Are we spread too thin militarily and how do we address that? What will troop rotations look like going forward? What should our force strength be? How much repair and replenishment of materiel is required and what will it cost? What resources do we need to commit in Afghanistan? What are the relative priorities?
I’d be interested in hearing the answers to those questions myself. If the Democrats keep it to tough policy questions, more power to them. If they let the hearings degenerate into Judiciary Committee-style character smears, that will tell us something about their ability to legislate with any seriousness at all.
