Again those figures had to be seen in context, how many soldiers did fight, how big was the population, what was the percentage of soldiers in the army compared to the civilian population.
I find it very difficult to compare casualties of modern (20th century wars) mass wars or total wars compared to the more restriced ones in earlier times (maybe 30 Years Wars as exception).
The First World War, which can be blamed purely on the Germans and Austrians is approx. 17,000,000, in a shorter span of time than the Napoleonic Wars.
I cannot subscribe to that at all - you ignore Russia seemingly completly and neither France nor the British Commonwealth were angels of peace and were more or less on a standby to go to war (in contrast to WW2)
