How does Trotsky compare to Snowball in Animal Farm by George Orwell?

Snowball is the definite 100% symbol for Leon Trotsky, just to clarify

And this is how the story goes:

Leon Trotsky was one of the leaders of the Russian Revolution, and grew to become very influential and powerful as a result, he was in charge of army command in the Russian Civil War (Reds vs Whites/ Commies vs. Czarists)

Trotsky is overthrown by Stalin, who exiles him from the USSR and spoils his reputation.

Stalin also removes any of Trotsky's honors and positions of Government, he gives everyone in the USSR the notion that Leon Trotsky was bad for the Revolution.

Leon's assassination was said to have been orchestrated by Stalin, but that is a topic of debate.

As you can see, Trotsky's story is remarkable similar to Snowball's:

Snowball was one of the leaders of the revolution against Jones. Snowball becomes a sort of hero to the Farm, and devotes his entire work to it.

Snowball leads the Animals against Jones in the Battle of Cowshed.

Napoleon overthrows Snowball and exiles him from the farm, and plants his tales of bad reputation in the Animals' heads.

Snowball was never seen after he was exiled from the Farm.
