Not sure why that would be the case. A lot of Brits understand that while Britain survived WW2 it was the US that came out strong and helped to end WW2 compared to any other nation on earth (except Soviet Union) with not only technology dominance but also economic and in many ways cultural.

This also has a personal bias as I want the US to be remembered and not the UK who I think has done so much damage around the world pre WW2 in the name of colonialism including my home country.
