A lot of the seemingly irrational and idiotic decisions taken by modern western politicians can perhaps be explained by the fact that they worshiped julius ceaser, alexander the great, napoleon, etc. at young impressionable age.
So sure we should study napoleon, but lets not worship him. In my opinion Napoleon is best remembered as part of the retreat from moscow. His army just a massive mob of running, freezing, starving men tripping along a snow covered path littered with frozen corpses and gold and silver and silk that they stole and realized they couldn't carry home. The great emperor abandoning his army and running quickly away on a fast sled, because he was already facing a coup at home.
