Squealer in George Orwell's "Animal Farm" represents the propaganda apparatus of the Soviet regime, specifically the Russian newspaper Pravda and Vyacheslav Molotov, a prominent Soviet politician and propagandist. He serves as Napoleon's propagandist and chief communicator, manipulating the truth to justify the pigs' actions and maintain control over the other animals. Squealer uses fear, lies, and distortion of facts to convince the animals that everything happening on the farm is for their own good, even when it contradicts their memories or the original principles of Animalism. His role highlights how propaganda is used to manipulate information and suppress dissent to keep the ruling class in power.
