Chapter III marks the beginning of the dispute between Snowball and Napoleon, which evokes the power struggle between Trotsky and Stalin. Squealer, who represents the propaganda machine, introduces fear tactics in this chapter. After convincing the animals that the pigs have a right to milk and apples, he threatens the animals with Jones’s return for the first time. The pigs have created an environment where their rules must be followed out of fear of the return of the old older. It is an easy, winning response to animals that see only the two alternatives and cannot see a way back to the utopian principles that inspired their rebellion.
