I suspect that ringing up the Kremlin and saying "A Seawolf attack sub right now has an excellent firing solution on your rather expensive ballistic missile submarine, no, I'm not bluffing, these are the co-ordinates, and we would definitely be able to recover it after we sink it given how close it is to our coast and how shallow the seas are. So how about we don't sink your submarine and recover your classified technology, as a sign of good faith, and we talk this out?" might be one way.
