Suppose they DO get their satellites back from Russian. How long do you think it would take their engineers to go over the satellites to determine that nothing had been tampered with, and to approve them for flight? I suspect it would probably be faster to launch the next flight's worth while reworking these and throwing away any Trusted Platform chips.
