Been looking for a quote attributed to Churchill, speaking to Truman about the Nuremberg trials, along the lines of "There but for the grace of God go we". And found this:

For those interested Grayling's "Among the Dead Cities" is a detailed study of carpet bombing (including that of Japanese cities even
before Hiroshima) and the moral issues it raises.
Not that I think Mr Greer is arguing from a point of conscience. I think Mr Greer just hates the country and the culture he's been fortunate enough to inherit.
(I was amused to hear the young leftist during the interview, criticise Churchill for having describe the religion of suttee and the caste system as "beastly".)
