we've seen the air strikes here around tripoli increase over the past couple of days, as nato is saying it's taking out the command and control infrastructure that gadhafi has here, telecommunication installations, here in tripoli as well as in sitre and those ammunition dumps. what they're trying to do is prevent gadhafi from communicating with his forces in misurata, as well as on the eastern front and trying to take his ammunitions away from him. also, as you mentioned, nato saying that they're going to step up that air campaign and they're warning civilians in libya to stay away from military installations. as you see them using predator drones and robert gates saying he believes the first predator strikes might have already started. we know from iraq and afghanistan that the predators are very, very good at precisely taking out targets and they can stay in an area of operation for a long time, hover there, find the targets and take them out.
