Squealer's job was to change the commandments
Squealer is the form of propaganda.
Squealer is propaganda, but specifically, Pravda
The Squealer - 1930 was released on: USA: 20 August 1930
Squealer represents propaganda towards Joseph Stalin (Napoleon)
Squealer from Animal Farm is an allusion to the Pravda, a Soviet newspaper/propaganda machine.
Squealer represents the propaganda newspaper Pravda rather than a person the way the other pigs in the novel do. The statement that Squealer can turn black into white was intended to refer to Pravda's ability to turn lies into truth. Squealer also carries the messages from Napoleon to the other pigs who simply take what Squealer says for gospel. In other words, Squealer is a method of communication from the top to the bottom with the ability to put the proper spin on the information. That was Pravda.
Napoleon wants the power of a leader, while Squealer is content to spread Napoleon's propaganda.
Squealer, dominantly, represents propaganda, but could be paired with the Russian newspaper company Pravda.
Squealer is the pig responsible for spreading the propaganda of Napoleon to the other residents of the farm. Squealer uses his skill at jargon and speech to keep the animals firmly under napoleons control.
When George Orwell describes Squealer as being able to "turn black into white", he is in fact referring to Squealer's persuasive skill. In other words, Squealer has enough persuasive talent to be able to convince the animals in Animal Farm that black is white or vice-versa.
He is the propaganda chief
