uk blockade of any resource import and bombing campaign usa unstoppable land lease and fresh supplies and troops.  ussr massive amount of manpower, the sheer size of the country, gigantic resources pool, the unrelenting willpower of people that quite literally just didn't want to get genocided. all the while germany lacked resources, had shit logistics, leaderships were full of themselves after easily defeating france, political policies literally drowe occupied populations to resist and most importanly, pissing off pretty much most of the world. they simply had no fucking chance.  even if they took moscow or caucasian oild fields, they wouldn't be able to permanently end ussr resistance. even if they somehow managed to hold on, usa would develop nukes and start dropping it on germany. even if they somehow managed to find some sort of peacefull solution, their war economy would implode because there's nothing to plunder anymore. td;rd everything went wrong after 1941
