Well, no one knows for sure. There are now two competing governments and various armed militias, tribes and clans. Secretary John Kerry and others have said they're hopeful a single government can be formed soon maybe in the coming weeks.

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.

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.

American Green Berets have been on the ground reaching out to some of the factions there. But don't confuse them with combat troops. So we're only talking about airstrikes now. If there are any troops that go in there it will likely be the Italians.

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.

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.

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.
