what are the main differences between napoleon snowball and squealer?

Napoleon, Snowball, and Squealer are pivotal characters in George Orwell's "Animal Farm." Napoleon is an authoritarian leader who prioritizes power and control, often using force and manipulation to maintain his rule. Snowball is an idealistic and passionate revolutionary who advocates for progress and innovation but is ultimately ousted by Napoleon's tactics. Squealer serves as Napoleon's Propaganda minister, skillfully twisting language and facts to persuade the other animals and justify Napoleon's decisions, often at the expense of truth and transparency.
