If your going to put Trotsky and Stalin on the same page, then if you wanna keep up with historical accuracy, since both of them hated eachother and had differing policies on Socialism, its either Trotsky or Stalin. Both were Bolsheviks but after Lenin's death, Stalin consolidated power after a power struggle with other Bolsheviks, including Trotsky. Stalin's policies conflicted with Trotsky, and Trotsky became hated and was then labeled an "enemy of the people" and exiled from the Soviet Union. Trotsky lived out the rest of his life out in Mexico, where he was killed by a NKVD agent named Ramon Mercader, who was chosen directly by Joseph Stalin to kill Trotsky
I will though say that you got the Cyrillic name for the soviet union right
