What would Snowball have done if he had ousted Napoleon?
This question is counterfactual, but fun to think of nonetheless. I do not think it would have been possible for Snowball to have ousted Napoleon, as Napoleon had the nine puppies from Bluebell and Jessie that he trained as killers. Napoleon would have never been happy to take a secondary role on the farm--early on in the book, he even took the cow's milk for himself in the early days of the Revolution. This shows that he is opportunistic and selfish. Snowball would have built the windmill, though he was too much of an ideologue to get the dynamos and cables needed to make it fully functional as an electrical source. This would have involved trading with other farms and unless the revolution spread and more farms lost their human masters, this would not have happened. Snowball was a purist in his goals, but without other farms following the lead of Animal Farm, many of his goals would have fallen by the wayside. Perhaps if the windmill failed, there might have been a counterrevolution among the animals.
