- The 3-gigaton warhead obviously doesn't care about a couple hundred meters.
- However, if you want to pull the sort of stunts that made the nightly news
- during the Gulf War (targeting individual buildings, etc.), it helps to know
- exactly where you're shooting from. (Yes, I know that the air-launched
- missles used in the Gulf used their own "eyes", and so this isn't the
- greatest example. Best one I could think of right now.) The military isn't
- worried about those who might have 3-gigaton warheads - at least not as
- far as fuzzing up GPS is concerned. The folks that have those sorts of
- toys don't need our GPS (and could have it anyway, if they DO need it, one
- way or another). But there's no sense making precision targeting any easier
- for the bunch over at Terrorists-R-Us.
