Yep - favoured pragmatic decisions which kept the revolution alive rather than world wide communism.You could talk about the NEP resulting in the need for 5 year plans and collectivization, you could talk about the precedent set by Lenin dealing with opposition using the Cheka and how it resulted in the excessive use of terror. For political I'd maybe mention how Lenin focused on practical approaches to running the country more than ideology, which resulted in Stalin adopting "socialism in one country" idea
