In Chapter V, Orwell also brings up the central difference between Trotskyism and Stalinism. As we have discussed previously, Trotsky advocated the extension of the Revolution on an international scale. In contrast, Stalin advanced the idea of Socialism in One Country, in which he stated that, considering the failure of communism in other nations, the Soviet Union should focus its energy internally. Stalin’s Socialism in One Country was a revision of Marxism-Leninism. Orwell mirrors these events in Snowball’s and Napoleon’s debate over how best to protect Animal Farm against another human attack. Snowball wants to send messengers to spread the message of the Rebellion. Napoleon wants to stockpile weapons and train the animals to use them. Just as Stalin revised Marxism-Leninism with Socialism in One Country, Napoleon has begun to hijack Animalism to serve his own ideals.
V takes Finch by surprise; resulting in a scuffle which sees Finch shoot V and V wound Finch with a knife. V claims that he cannot be killed since he is only an idea and that "ideas are bulletproof"; regardless, V is indeed mortally wounded and returns to the Shadow Gallery deeper within, dying in Evey's arms. Evey considers unmasking V, but decides not to, realising that V is not an identity but a symbol. She then assumes V's identity, donning one of his spare Guy Fawkes costumes. Finch sees the large amount of blood that V has left in his wake and deduces that he has mortally wounded V. Occurring concurrently to this; Creedy has been pressuring Susan to appear in public, hoping to leave him exposed. Sure enough, as Susan stops to shake hands with Rose during a parade, she shoots him in the head in vengeance for the death of her husband and the life she has had to lead since then. Following Rose's arrest, Creedy assumes emergency leadership of the country, and Finch emerges from the subway proclaiming V's death.
