Remember when Britain sank the French navy after the Vichy govt. collaborated with Hitler?
Oh, yes.
I also remember Vichy French forces firing on Americans when we were entering Morocco. Not much, they surrendered fast, but it was there.
I've been an avocational student of military history for ~35 years, since I was around 10, and know my WWII history pretty well. Watching the French now, and looking back more critically, I see the French in WWII as less and less an ally, and more and more as a slight impediment / obstacle. A good number helped our cause, but they were probably about evenly offset by those who didn't, and worked against us / at cross purposes to us.
