surprise. this time general mcchrystal has made a very deliberate decision to let the word go out because what he hopes, at least, is the taliban will pack up and leave. his troops can move in, provide security, and that there's no place for the taliban to come back to. but it's a risky strategy. >> let's talk about the risk. what are the risks of talking about an operation that you're planning ahead of time? >> what if the taliban don't just pack up and leave? as atia pointed out in her report, they have ieds, mortars, rocket propelled grenades. this is also very tough terrain. this is an area that is interlaced, if you will, with irrigation canals, mud brick walls, a farming area. this is going to be an area where you're not going to see armored vehicles, but you're going to see troops moving on foot, very slowly, trying to gain ground inch by inch in an area that could be laced with those ieds, tony.
