Maybe Skuzzy would be so kind to do that.
Anyway, my shot at it is that at least the French and the UK went to war against nazism which is an extreme form of fascism. It was mingled with old grudges, worries, and agression.
Then, the UK carried the banner when the lines were clearer.
The USA had no intention on any war against fascism, and were on the sideline while the UK fought for its survival. Even after the BoB, there was not much of pro-Brit direct aid from the USA. (I can explain this with some lines hard to swallow...for those from the USA that do not know)
When WW2 became a total war, it was basically Fascism vs the others.
The fascist were completely defeated in the war....but the idea lives, and some countries dally with the policy.
And the intardnet is also full with fascist speculants....
