My point which I failed to explain was that the dolt who made the comment about Iraq being unable to control a UAV over long distances failed to consider that one can just stick an off the shelf GPS unit on a UAV and make it flay to a waypoint to drop its anthrax spores or other payload.

Especially if your target is as big as a city.

.....or.....just preprogram a flight path and altitude(low) and send it on it's way.....

Yes, but my point was that the degraded GPS signal would affect the "off-the-shelf" GPS receiver's performance, and could make the GPS-guided UAV so unreliable that it might erroneously fly over to Saddams' palace and dump its load. Since they probably know that, it's probably a no-go for them using GPS for that application.
