This is the jump to conclusions to beat 'em all. No more calls please, we have a winner.
GLONASS is the Russian version of GPS (which is an American product). Some newer GPS devices (can) also use the GLONASS network.
There's no "holding hostage" of 911. If GLONASS can give a position that enhances the location of a person calling 911, the data would be used. If the Russians "withheld" the data, like this alarmist "news article" suggests might happen, my fellow 911 operators and I would just get a caller without any enhanced position information (or with information from sources other than GLONASS).
The only way that GLONASS could cause harm to a 911 caller is if the location provided was completely wrong in orders of magnitude, and the conflict between that and the phone's onboard GPS was overlooked, and the 911 operator deliberately chose to ignore whatever other position information was obtained from either GPS, tower site info, or caller interrogation, and used strictly the GLONASS-provided (wrong) location.
And people who think that Russians would go to that kind of length to affect the life of one specifically random 911 caller in America, their tinfoil needs tightening.
