I intentionally didn't say "the population of Russia". Occupying an enormous land mass takes an enormous amount of time (arguably infinite) and resources.

OK, Napoleon is right and he's "conquered" Russia in a month. Are all of those troops being sent home before winter?

Napoleon was never going to go to Vladivostok. You do know that most of Russia is empty apart from the western part? So in effect if you capture Moscow and a few other major cities you are done.
