Old Major closes his speech with the final two sentences—"All men are enemies. All animals are comrades"—to emphasize the necessity of unity and solidarity among the animals in their struggle against human oppression. By categorizing all humans as enemies, he seeks to clearly delineate the opposing sides in the conflict: humans versus animals. This binary framing serves to solidify the animals' shared interests and collective identity, urging them to recognize that their true struggle lies against the exploitation and domination imposed by humans.
Furthermore, by proclaiming "All animals are comrades," Old Major fosters a sense of fellowship and mutual support among the animals, encouraging them to work together towards a common goal. This rallying cry is meant to inspire a sense of purpose and encourage the animals to set aside their differences in order to fight for their liberation and a better future. Overall, Old Major's concluding statements serve as a powerful call to action, reinforcing the themes of solidarity and resistance against oppression that permeate the narrative.
