False. [general good stuff by Phil elided]
Last time I looked, the Pentagon was more than 100 meters in diameter. One of Phil's later posts talks about SA being in a 100 meter range. Obviously the Coast Guard and FAA want pretty good accuracy. Whatever the actual numbers on the error terms are, either a moderate high explosive, or tiny nuke, guided to within 100 meters of the Ground Zero Cafe will probably take out all of the above ground portions of the Pentagon. Look at what a single smart bomb (a fairly small one at that) did in the Pentagon's favorite Gulf War video. Similarly, just off the Naval Acadamy's grounds is a huge array of naval communincations gear. It wouldn't take much to put atserious hurt in the Navy's C-cubed net. And you could easily use GPS to get close, and then image recognition for final targeting. Seems to me that the important concept here is that this is yet another technology that the government can't control once its out of the bottle. The scare tactics, and worrisome quotes about "terrorists and drug dealers" will cause confusion among the masses, but I can't see them having any long term effect.
