Tom,

Normally I let this veiled US bashing pass.  The US
can induce errors into the GPS system due to the fact
that the US conceived built and launched it.  Is it
useful to the rest of the world?  The US hopes so. 
Can anyone use it?  Of course.	During a conflict if
it is determined that a foe is using GPS data for
accurate targeting will the US decrease the
un-encrypted accuracy.	Most assuredly.

As for the spoofing of GPS.  It is based on a time
error that will cause system wide accuracy to decrease
to approx 100m accuracy.
