While I dislike the French as well, those characterizations aren’t true.
Their aid is what pushed the American revolution in favour of the colonialists.
And they distinguished themselves in battle in world war one where most of the bloody battles were fought on French territory.
Their fault is linked to the French revolution when they destroyed their culture, and gave up their leading nation role. They elevated nationalism to replace religion and that is their cardinal fault
Thank you for the education. (Sincerely...)
