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.
