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.

But clearly the fact that we've gone from zero Iraqi security forces on duty in May to up to 200,000 today is an enormous accomplishment, but it's not enough.

We've got to ensure that the quality and the capability of these forces will be good enough to withstand the challenges that the insurgents and the terrorists will present to the new Iraqi government.

You don't build a new power plant in the United States overnight. It takes years to build.

And over time, I think, as Iraqi security capacity builds, you'll see American and coalition presence there decline.

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.

It's clear to me now that we've got to reach out to the Arab Sunni community in particular in an effort to cause some moderate political activity to take place so they join the future of Iraq.
