If you want to see shock on the faces of the committee then you need to watch the second panel regarding the political situation on Iraq. Actually you should set aside time to watch all of the preparatory sessions of the various cmtes.
You can do it by selecting the videos at the C-Span link.

The hair-raiser, was featuring, Stephen Biddle, Nir Rosen, (can't recall first name)Said, and another gentleman. They have impressive credentials and their views are quite diverse in some regards, not so in others. Especially interesting was Nir Rosen who has spent most of the past five years in Iraq and other surrounding countries.
You won't be sorry you watched this, another panel were retired miliary brass focused on the military angle.. Odom, McCafferty and a couple of others.
There was another session today and I may be able to pick it up on replay later tonite -- Haven't been home today.
