I was going to bring up the same point as TOM--the American Revolution came before the French Revolution.
But then, without the French, we never would have won the American Revolution. So WW II was a payback.
De Gaulle led by ego. For years, French children were taught that it was De Gaulle leading the free French with the Americans and British following that defeated the Nazis. De Gaulle was against the entire plans for D-Day insisting that his ideas (which is what Hitler also thought) were best and he should lead all men. All military leaders aligned with the Allieds recognized Eisenhower as the supreme commander--except, of course, for De Gaulle. He was himself in the role. Today, if you go to the French military museum at the Invalides, only twice in the entire WW II exhibit are the British or Americans even mentioned.
And as Tocqueville pointed out, in France, there is more of a let's let the government do it, while in America, it's more, lets just get it done. I'm not saying one is better than the other, I'm just pointing out the difference.
For years, French was the international language of diplomacy and business. Today, it's English. The French see the English language taking over everything and they are trying to preserve their culture and heritage. Only the way they go about it makes them see somewhat arrogant and dismissing of others.
But when it comes down to one-on-one meetings with individual French citizens, I doubt any of this will matter. They will be happy to show off their country and help you get around. All they ask, is you at least "try" to speak French.
