I didn't say they were the same thing. But anyway, the Napoleonic Wars was the most destructive conflict of the 19th century bar the Taiping Rebellion. As a percentage of the population France lost more men between 1799-1815 than they did in either WWI or WWII. Hardly rash to suggest the Napoleonic Wars were a/the major reason for France's terrible demographics in the 19th century, and most historians accept that it was.
