This is understandable. They really don't have a great track record as an ally, although I think the French people have a better conception of how America saved them in WWII then we think they do.
And yes, they still think that they're a superpower, which is laughable, being as they haven't won a battle since Napolean led them.
And yes, the French monarchy supported the Revolution on the grounds that they were fighting England through our war. I've been to Yorktown, though, and there is no measure to how they really helped us in that war - without them, it would have taken alot longer to win that war, and cost more lives. There are monuments on the James River to the French Navy, many of whom died fighting with us.
Ironically, it was the very war that they supported that would end up being the end of their own monarchy, as it was the American Revolution with its idealism about the rights of men that led to the French Revolution in 1789, with the cries of "Liberty, equality, fraternity". Thomas Paine was also a large contributor to that Revolution in intellectual department, though I think they almost hung him after the Reign of Terror.
And from then it has been the slippery slope into crazed imperialism for them, ending after WWII. I honestly think that it is just a bitter nation consumed with the fact that they are not as imporatant as they once were, and that no one listens to them on the world's stage.
And I do think that we paid them back dually for the Revolution in WWI and WWII.
