[emphasis added] Firing on surveillance satellites is an insane thing to do, because (as you point out) it's a very threatening move. I would be very surprised to see missile defence and antisatellite attack combined under the same automatic-response system; it's too dangerous. Furthermore, there is no terribly good reason for it: the missile-warning satellites tend to be in geostationary orbit, much too high for most proposed SDI systems to attack them effectively, and hence it isn't even the same hardware doing the job. You have constructed a frightening scenario, all right, but it's based on the same assumption I was attacking in the message you cited: that a system which *must* have super-fast and hence automatic response will also command other, much more dangerous, systems into action. This is definitely a possibility which needs to be guarded against, but there are enough false alarms in existing systems (as you point out) that it is *most* unlikely that anything which didn't *absolutely* *have* to have lightning response would be placed under fully automatic control. There is no need for 60-second decisions about attacking satellites. > ... Because of [shortening decision times], our destiny will be put > in the hands of ``expert'' computer systems.

All the more reason to support a system that lengthens decision times on the really bad weapons, by reducing the fear of sudden obliteration that motivates worrisome ideas like "launch on warning". -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
