While that might be true for US, UK and Russia, I fail to see how China and France won WW2.
Same applied to japan and china.
Beware the overwhelming Eurocentrism of WWII history as well, China was heavily involved throughout the duration of the conflict and took 3-4 million military casualties with 7-8 civilian casualties in the Pacific theater of WWII, second only to Russia (ignoring the losers).
