In George Orwell's "Animal Farm," Napoleon's initial reluctance to support the construction of the windmill stems from his desire to maintain power and control over the other animals. When Snowball, who is a proponent of the windmill, introduces the idea, Napoleon initially opposes it. However, he later changes his stance after expelling Snowball.
A direct quote illustrating his opposition to the windmill is when he says, “Comrades, do you not suppose that we are capable of taking care of our own affairs?" This quote reflects his belief that the animals should rely on their own strength and that any innovations could potentially disrupt the stability of his leadership.
After Snowball's expulsion, Napoleon exploits the windmill project to strengthen his control over the farm, claiming it as his idea. The shift in Napoleon's view highlights his manipulative nature and ability to alter narrative for his benefit while using the windmill for propaganda to unify the animals under his regime.
