In George Orwell's Animal Farm, Squealer tells the animals about their doubts regarding trading by using persuasive language and propaganda techniques. He convinces the animals that trading is necessary for the success of the farm and that the pigs are making sacrifices for the good of all. Squealer also uses fear and intimidation to silence any animals who question the pigs' decisions. For example, he tells the animals that if they don't trade with Mr. Whymper, the farm will fail and Jones will come back to take over. Overall, Squealer uses his skills as a persuasive speaker to manipulate the animals into accepting the pigs' decisions and ignoring their own doubts.
