The military has little to worry about from this, at least. They are many years ahead of Cornell. This was a consideration when the GPS system was created in the first place. The military has ways to spot spoofing.

During the war, the Iraqi's tried to jam the GPS signals, rendering the sat-guided bombs inaccurate and useless. The Air Force just grinned and set their toys to home on the jammers.

Yep this is a non-event !

Ways to spot spoofing and I’d wager much more advanced ways to trick any enemy who is trying to leech onto our GPS network and use it to his own advantage, or spoof any other system of GPS satellites put up by future enemies. I foresee a day when the next fugitive Saddam Hussein, trying desperately to blend in, drives his beat up old jalopy right up to the SpecOps team lying in wait to kill him.

FYI the military does not use GPS. It uses a parallel system called PPS (Precision Positioning System) that is much more accurate and ... encrypted. Spoofing is way harder on time-sensitive systems (i.e. GPS/PPS) that are encrypted (basically it’s not possible).
