The U.S. is not the only country with GPS satellites... :)

True. The Russians have the GLONASS system. That's about it.

There is a European system called Galileo in development and a Chinese
system also in development, but right now the only operational systems
are
by the USA and Russia and they are not compatible.

Russia Challenges the U.S. Monopoly on Satellite Navigation

As an unqualified to judge layperson, I don't think Loran should be shut
down. The USA is becoming totally dependent on *one* system for commerce,
commercial shipping and military applications.
The potential damage or risk to any of them is a matter of national
security. To operate without a backup system is foolhardy.
