That's entirely the point of putting them on submarines to begin with. It's a very old problem; no sane person would murder millions of people even as a retaliatory action. So what's the point of having The Bomb at all? The solution, as in Doctor Strangelove, is to take control out of your own hands - you put yourself in a position where you can say "I would never launch nuclear weapons, heavens no - but I can't speak for the commanders of my nuclear subs if their country is obliterated in a first strike. Who knows what they might do..." I'm rather disappointed that Jeremy Corbyn doesn't seem to have appreciated this fact, as he is currently being raked over the coals unnecessarily for his entirely sensible public reluctance to murder millions of people. In fact you don't want someone who looks trigger-happy, as that incentivizes a first strike against you.
