Germany held a piece of France in WW1. If America had not entered into the lines when it did, the German Michael offensive might have had more success. The French had been bled dry after a mutiny and Verdun.
Britain couldn't help the French, they had been depleted at the Somme and Flanders. The Germans knew they had to break through before the weight of 1 million Americans hit the trenches.
American units such as the American 369th Infantry regiment(black)fought along side the French.

That was WW1.

WW2, the French surrendered......in the same railcar used for the Armistice in WW1... to the advancing Nazi's and were subjugated as the Vichy French until June 6th, 1944.

So, yeah....the US has saved the French butt.....twice and wound up taking over for them in VietNam after they surrendered.....again

Britain needed a “Brexit” in 1941. Germany was no threat to the British Empire. France was more their traditional rival than Germany was.
