Because they didn't think they couldn't lose, and now they have no idea what to do. None.
To abuse WWII analogies, Hitler directed all Barbarossa planning under the assumption that the Wehrmacht could not lose. There were no contingency plans for the possibility they might make it to Moscow late, no rear defenses in case they got pushed back, no plans for how to break an encirclement, because defeat was impossible. Consequently, when things first began to go badly at Moscow, everything from then on was Hitler flailing and making increasingly bad decisions because, even as Germany began to be pushed back, Hitler still could not psychologically accept that defeat was a possibility. Hillary was supposed to win in 2016, already nearly a decade ago, and they were supposed to be doing their victory dance over the corpse of the nation-state as we evolved fully into gay space communism. They have no idea what to do now. Stealing the 2020 election was a panic move that didn't fix things. They're just flailing like retards, hoping Steiner's counterattack will save the day.
