There still were two nuclear explosions and two SLBM launches
So in effect, neither Russia nor the West reacted when the two subs launches SLBMs that eventually nuked each other--possibly in the Med?
Wow.
The two hijacked nuclear-armed subs posed a major threat. Nuking each other solves the problem. Russia and the US were working together and in communication, so no reaction needed, except to clean up the nuclear mess afterward, if possible.
