After Old Major(Lenin)'s death, Snowball and Napoleon struggled to be the successor of the great leader. Their political battle continued as they oppose each other in everything. Snowball wanted to encourage rebellion in other neighboring farms, whilst Napoleon focused more on Animal Farm. This is related to Stalin and Trotsky's struggle for power after Lenin's death. Trotsky was an idealist, proud and noble whilst Stalin was pragmatic, quiet, and manipulative. Stalin trained KGB---his pets that will do whatever he wants, which is similar to Napoleon's "education of the dogs". Trotsky had also wanted to spark communist rebellion in other parts of the world. This power struggle ended when Stalin/Napoleon drove/exiled Snowball/Trotsky from the Animal Farm/USSR with the help of KGB/dogs.
