I think more the Germans wanted to control more of the continent, since they didn’t have the colonies that France and Britain had, but the French and Brits didn’t even want them to have that.
Actually, there were a few dreamers in Germany, but the majority wanted peace.
But it was not that Napoleon created Germany. He created a resurgence of German nationalism, but we have been here as a country since 962 AD 😀 It was just that the First Reich, as it was called, had become moribund in the latter half of the 18th century, so it eventually fell prey to the French invader (a long story, but this is how it ended).
