Everybody needs to understand that I learned Arabic from the United States Army as a second language. I never spoke it at home.

Well, the hardest thing to do, as we know from our own experience on 9/11 is protect everything all the time.

Capturing any member of any terrorist cell or any insurgent cell that we may happen to come across is always very, very valuable, and the thing that interests me is that in most instances after a time people talk and they tell us what they know.

But my Arabic is pretty good. It's good enough to have conversations with people, to understand what they say, to understand what they're feeling.

Undoubtedly, there are members of the former regime that are cooperating in some fashion and then there are extremists that are within Iraq that are cooperating with them.

But the key shift in focus will be from counter-insurgency operations to more and more cooperation with Iraqi security forces and to building Iraqi security capacity.

And so I think that if the person has the funds, the network, and the equipment to do this, and also the experience, which is the key factor, then they can be quite deadly.
