Recent events recall this passage from Sinclair McKay’s book about the fire-bombing of Dresden in February 1945. In the years following the war, those who had been involved in the operation wondered about the necessity and the morality of what they had done.
The young scientist Freeman Dyson, who had worked in Bomber Command and who had come to feel a revulsion especially for the raids carried out towards the end of the war, found himself discussing the Dresden bombing raids with a ‘well-educated and intelligent’ wife of a senior air force officer. Dyson asked her if it was right that the Allies should be killing large numbers of German women and babies. She told him: ‘Oh yes. It is good to kill the babies especially. I am not thinking of this war but of the next one, twenty years from now. The next time the Germans start a war and we have to fight them, those babies will be the soldiers.’ There was something quite extraordinarily primitive about this exterminating impulse that stayed with Dyson for decades.
