States consider their satellite systems part of their anti-ballistic early warning shield and critical infrastructure. If a satellite gets taken out, they HAVE to assume that their enemies are clearing the ground for an all-out ICMB launch and if they go blind, they HAVE to assume the enemy missiles are already in fight and launch theirs. This is also the reason why a Chinese satellite must have been chosen and not a Russian one, several of theirs are integrated into the Perimetr system with with no-launch signals getting broadcast as a fail-deadly dead man's hand deterrent. Several of their satellites are broadcasting these signals, and it is impossible to know which one is actually "live" and wired to send out the signal for an immediate ICBM launch.
