Why do some British dislike the fact that Americans helped them in WWII?

We don’t dislike the fact that Americans helped us. We appreciate the help, both military and on the Home Front from the likes of Ben Lyon and Bebe Daniels, who came over here when many of our own performers suddenly found pressing business in America, and played a big part in raising morale.

What we dislike is the claim that Americans won the war all by themselves or, worse, the claim that Americans saved our sorry donkeys (that doesn’t sound quite right, does it?) or that but for them we’d all be speaking German. By the time the Americans turned up the threat of invasion had passed. Anyway, if it weren’t for us the Americans would be speaking Dutch.
