Had Trotsky won, his USSR would have been, ironically, far more bureaucratic than Stalin’s, and that is not necessarily a bad thing. The problem with Stalinism is that it was not bureaucratic enough. A powerful bureaucracy means greater stability and less terror.
Because genuine marxists are for workers democracy, not stalinist bureaucracy. So instead of idolizing the ussr, it is critiqued and understood why it failed. Idk read revolution betrayed.
