Most were just glad it was over, many who understood the bomb's capacity were relieved to have developed it before any adversary, and concern was often over wise future use of the atom rather than over the morality of what had happened - and US feelings were widely shared: see the British cartoonist Low's famous comment at https://www.cartoons.ac.uk/record/LSE1258. Outright condemnation was a minority viewpoint, and seems rather surprisingly to have come from religious and traditional perspectives rather than from the left which might nowadays be associated with it. Francis Walton wrote to the New York Times on August 11 of "indiscriminate, inhuman and un-Christian bombing of cities" as "simply mass murder, sheer terrorism on the greatest scale the world has yet seen" that had reduced its perpetrators "to the spiritual level of the Nazis". Walter G Taylor in Time (letters, August 27) added, "The United States of America has this day become the new master of brutality, infamy, atrocity." John Haynes Holmes, Minister of the Community Church of New York New York City (Time, letters 19 Nov 1945) denounced the use of the bomb "under whatsoever circumstances as a hideous atrocity and an outrage upon every principle of ethics and religion. Our nation stands disgraced before the world as the perpetrator of this monstrous crime". David Lawrence, founder and editor of US News and World Report kept up a steady attack, writing on 17 August "Military necessity will be our constant cry in answer to criticism, but it will never erase from our minds the simple truth, that we, of all civilized nations, though hesitating to use poison gas, did not hesitate to employ the most destructive weapon of all times indiscriminately against men, women and children," adding on November 23 "We have used a horrible weapon to asphyxiate and cremate more than 100,000 men, women and children in a sort of super-lethal gas chamber— and all this in a war already won or which spokesman for our Air Forces tell us we could have readily won without the atomic bomb."
