Fair point, well made. But at least they did not have to ask a Frenchman called Lafayette for help.
Just saying 
America did much more than that. They sent Adams and Franklin to France to petition the King for help. It took years, and Franklin had become quite the social center of attention in Paris. Adams just wanted to go home.
Of course, it wasn't long after US independence was secured that France went through their own revolution, that finally evolved into a miniature narcissistic sociopath named Bonaparte leading Europe into war and chaos for many years. Napoleon the 2nd insisted on provoking America with his interference in Mexico during our Civil War. Britain sympathized with the Confederacy, but needed the commerce with the Union. The Trent Incident nearly caused a war between the Union and Britain. Lincoln thought one war at a time was the wiser choice. Tensions abated as neither nation wanted conflict.
America eventually paid its debt of blood back to France, at least twice. If anyone thinks that the French didn't appreciate this, just visit the American war cemeteries maintained by France... They remember. Get past any nation's elitists, and you'll find the simple folk, who need no convincing that war is bad... They remember, because they were the ones to bare the suffering of conquerors and their wars for power, riches and idealism.
