The SA article that I referred to is in the December current edition.   The GPS system can be easily and cheaply compromised by a motivated individual or entity.  GPS signals as they reach earth have very low power.  A hacker near a receiver ( think a 747 approaching a landing) can blast meaningless noise at the same frequency, making it hard for the receiver to stay connected to the signal.  Ships, planes, cellphones, and more are vulnerable. 

Other nations have a backup system that have transmitters from various different ground based locations. Their signals are much stronger and far more difficult to jam.  The US has none of those backup abilities.
