All wars are crimes. See gods. Well, some.
See man's laws before and after this.
But was bombing of civilians legitimate?
Ah that is the question.
Was the bombing of civilians in London legitimate?
Personally I am not a fan of Monday morning Quarterbacking decisions made in WW2.
But the United States Army Air Corp. made a point for about 2 years of not following the British example and bombing major population centers- instead focusing on strategic industries. That changed in 1944 I believe- and was a conscious decision- which was much protested within the ranks of the Army Air Corp.
There was a vigorous discussion regarding the use of incendiaries in Japan- and there were groups within the Army Air Corp who disagreed. I believe in the end Hap Arnold won out.
I think it is just too easy to condemn those who made these decisions now- in our safe homes. But in those days there was a real sense of a threat- and virtually every family was sending loved ones to war.
Better I think to try to avoid killing civilians moving forward- we will continue to bomb- but we can- and are- bombing smarter.
