Hey ! don't compare Napoleon and Hitler ! they aren't at all the same!
Seriously, I just remember you that Napoleon has declared war to nobody !! Actually, almost every european Empires were allied against France when they were still in the mess caused by their revolution. England see the weakened France of that time (France was most in anarchy then in republic after the revolution) as a great opportunity to invade finally that country (it looks like the final dream of a whole people looking to history).
The only bug was that actually the amazing opposite happened: when austrians, spaniards and brits were discussing about how they would split France between each others, Napoleon took the power in France. You know the result, France hasn't been invaded and all other empires (except England of course) have been invaded.
Well, I'm not saying that Napoleon was an angel, he was of course an awful warmonger, but he doesn't deserve to be compared with Hitler. Hitler has declared war to the world, Hitler has decided the destruction of a people, and you know everything else.
I know most people in here are anglo-saxon and their fear of Napoleon goes through generations, but please, don't put a "!" on his name as if he was Hitler.
If I want to do a little irony, I would say Napoleon is the only french leader who wanted to invade England, when almost every english leaders 'till Loyd George has ever dreamed of the union jack flying over Paris.
