In terms of the cost, no, we don't have a determination of that, but I can tell you we have looked at our involvement, even before we made the decision, of where things need to go. The military portion of the operation is one aspect. It buys you time to deal with the real problem, the political situation that's there.
A lot of the work that I've been doing with my counterparts is also focusing on that political piece. That's why we push for, and it was accepted, to have the military liaison teams that are working within those governments. As the liberation of Mosul takes place, we're also working on making sure that the unity remains, because the work that's going to be done after is going to be absolutely crucial to making sure that there's stability. These are not my words that I am about to say here, but if we don't get that piece right, we don't know what the great-grandson of al-Qaeda is going to look like.
We do need to have a lot of focus on the development, the displaced folks there, and the political situation is going to be essential. How we support Iraq and the region is going to be critical, but we're not going to do it alone. We need to be doing it with our coalition partners.
