The end of WWII sparked the decline of colonial Britain, a lot of changes in society, and people's worldview though... And Churchill was 70 years old in 1945. I know it might be "ageist" to say this but... People that sort of age have entrenched views and very, very rarely change them. You can't point out postwar societal attitudes and expect that Churchill should have shared them, he grew up pre-war, pre 1st World War even, when British colonialism was still swinging away. He had the attitudes of an 1800's British colonialist, because that's what he was.

You can't plonk any historical figure into another timeline and expect to come out with anything other than utter nonsense to be honest. Trying to use modern day values to assess someone born 150 years ago is meaningless.
