Valerie Fitzgerald said this quote

“ I don't think there's any deep psychological reason. It isn't comparable, say, to America's involvement with Vietnam and the emotional scars that that has left behind. A much more cogent way of looking at it is that the British have suddenly realized that they have their own equivalent of the perennial western. We have an immense, extremely colorful, diverse history of the empire, and I think people are just beginning to realize that there are jolly good stories there for the telling. ”
