Just let me provide some context first. Certainly, there are and continue to be targets to strike, so this notion that there aren't targets for air strikes is not, in fact, correct at this point.
With respect to security for humanitarian efforts, I'm going to ask my colleague to talk about that in a second, but it's important to note that the Iraqis and the Iraqi security forces don't want our support on the ground in the fight. They actually want to own that fight. They see it as an Iraqi fight to take forward.
