Well, Ramadi is a provincial capital of Anbar province. It's a sprawling city west of Baghdad. It's a poor city, endless cinderblock houses and high-rises almost as far as the eye can see.

Right, because they're looking at also organizing the Sunni tribes up around Mosul to take back that city as well. That's the second largest city in Iraq. That's going to be a very, very tough fight. And the Shia militias were not used in Ramadi, and we're told by the Iraqi generals that they don't want any Shia militias up in Mosul, either, to take back that city. So - but again, that's going to be a very, very tough fight.

To the extent people can't solve a problem, they tend to ignore the problem.

Absolutely, it's a Sunni area. So the key here, once Ramadi is taken that you have the Sunni tribal fighters, Sunni police in there patrolling the city.

Well, at this point, it looks like the Iraqi forces are moving into the city center itself. Now they've been working on this for seven months now. The American military's been pushing them and encouraging them to really get into the city and rout ISIS. So now they're finally doing it.

There are a lot of car bombs and roadside bombs, house bombs, even, in this city planted by ISIS. So - but it's going to be a tough fight ahead, and the Iraqi generals expect to take the city back, the city of Ramadi, by mid-January.

The U.N. is asking Italy to oversee this effort. And if a government is formed, you're likely to see up to 5,000 Italian troops maybe go in to provide security and also train a Libyan army.
