the curious thing is France wanks are always based either on Seven years or on the first Napoleon
There is a very good reason for it.
The 7 years war was one of the most important moments in world history since it defined which european country would be the most dominant in shaping the whole world.
If you look at the world map before this war, the french empire was one of the most important in the world and was building dominating positions in the most strategic areas of the world : India and north America.
At the end of this world, this first french empire was wiped out.
Napoleon was France's last bid to turn the tide of events and rebuild a new kind of french supremacy that could overcome Britain's growing world empire. It failed not because it was hopeless but because of Napoleon's faults and mistakes at the moment he was precisely succeeding (the years 1808-1812).
When the british took care to deprive France of Rhineland and what was going to become Belgium, it un onciously forever destroyed the possibility for France being again a rival for world domination since it deprived France of one of the key european areas for any future industrial superpower.
So, from 1815 on, one of the main objectives of french diplomacy was : never again a conflict against the UK. From 1815 on, France always yielded to british demands.
This is not that France did not have many great scientists, engineers and entrepreneurs. It did have many. But it decisively lacked coal and iron, so the french industrial production was much smaller than the british and german ones.
By the same way, Britain did the catastrophic mistake to give Rhineland to Prussia. Which enabled Germany to concentrate 2 supercenters for industrial power : Rhineland-Ruhr + Silesia-Saxony.
