Answer:
Step-by-step explanation:
Lenin had several doubts about Stalin's ability to lead the Soviet Union, especially in the context of the power struggle that followed Lenin's incapacitation in 1922. In December 1922, Lenin wrote a letter to the members of the Communist Party's Central Committee, commonly known as the "Lenin Testament," in which he expressed his concerns about Stalin and other Party leaders. Some of the doubts that Lenin had about Stalin in 1922 were:
Stalin's rudeness and lack of manners: Lenin criticized Stalin's behavior towards other Party leaders, calling him "too rude" and noting that he had not been able to use his power "with sufficient caution."
Stalin's thirst for power: Lenin expressed concern that Stalin's position as General Secretary of the Party could give him too much power, stating that "Comrade Stalin, having become General Secretary, has concentrated enormous power in his hands; and I am not sure that he always knows how to use that power with sufficient caution."
Stalin's nationality policy: Lenin criticized Stalin's handling of nationalities issues, noting that he had been "careless or even callous" towards the needs and aspirations of minority nations within the Soviet Union.
Stalin's relations with other Party leaders: Lenin expressed concern that Stalin's relationship with other Party leaders, including Trotsky, Kamenev, and Zinoviev, had become strained and that this could harm the unity of the Party.
It is worth noting that Lenin's doubts about Stalin were not widely known at the time and only came to light after his death. Nonetheless, they contributed to the ongoing power struggle within the Communist Party, which ultimately saw Stalin emerge as the dominant figure and the leader of the Soviet Union.
