I believe France was well paid for that little bit of help, I am sure you don't really believe France did that out of the good of their own hearts do you? If so, might I suggest a few historical references to the contrary?.
France is as they always will be, a back stabbing bunch of cowards. On the other hand I can count many,many instances where American blood paid for France's freedom, and we did not do it because we were being paid in cold hard cash. Thus is the difference between us and them. Pleased note, I realize that most of the English population likes America and Americans and vice versa, it's just the communistic/Muslim crowd in England that do not, and are the most vocal.
Keep in mind, though, that the French assisted we Yanks as an extension of their campaign against the Brits, and that the French administration which provided said aid a few years later had an appointment with the invention of Dr. Guillotine.
