The German Army in WWII still ran on horses. The US Army, with the jeep and the truck, was the first real motorized army. The speed of a horse didn't change from 1806 to 1940. The author neglects to mention the defeat of the French in 1870 during the Franco-Prussian War. They haven't been successful at war since 1808.
What bugs me about the French, is their arrogant superiority and their willingness to shove it down our throats. Nothing America does is right, but somehow we still win. They hate that. Americans haven't attacked any French restaurants or boycotted French movies.
Actually the French won the war against Austria in 1809. They also won in the the war against Austria in the 1850's in Northern Italy, Crimea, World War I and numerous colonial campaigns. I have no idea where you come up such assertions that they have not won since 1808.
