Nobody disputes, I believe, that our nuclear weaponry is negligible in comparison with that of Russia: if we could destroy 16 Russian cities, she could destroy practically every vestige of life on these islands several times over. For us to use the weapon would therefore be equivalent to more than suicide: it would be genocide – the extinction of our race – in the most literal and precise meaning of that much abused expression. An officer may, in the hour of his country's defeat and disgrace, commit suicide honourably and rationally with his service revolver; but in any collective context the choice of non-existence, of the obliteration of all future hopes, is insanity.
