IOTL, Soviet Russia didn't have to cede Georgia, Azerbajian and Armenia to Ottoman Empire. What if they were forced to renounce these territories after Brest-Litovsk and for some reasons, couldn't regain them after Ottoman Empire collapsed? Would the loss of Baku be fatal enough to the Soviet's industrialization efforts (I heard that the oil in Siberia was not discovered yet during this period) and eventually lead to their defeat during WWII?
