Should we have celebrated VJ Day? Hearing the hieratic tones of the Emperor Hirohito on Radio 4 the other day, announcing the unthinkable — the surrender of the great imperial power to the secular, gas-guzzling, unheeding West — seemed like a profanity. So much came to an end with that surrender that it is not possible to celebrate it, particularly since the method chosen to defeat Japan was nuclear-fuelled genocide, not once — which would have been unforgiveable enough — but twice.
