What makes the animals accept Squealer's explanation of the windmill in chapter five of Animal Farm by George Orwell?

Here as
elsewhere, the animals are vulnerable to 's shameless lies. They passionately believe in the
Animalist revolution; they want it to be a success. So wheneverinstitutes a sudden change of
policy, as here with the building of the windmill, they tend to think it's all for the best. The
animals have projected all their hopes onto Napoleon; they have to believe in his infallible
wisdom, strength, and indefatigabilityotherwise their faith in the whole Animalist project will
start to weaken. Squealer cleverly manipulates the animals's psychology to get them to fall into
line behind the regime.

Besides, Squealer is very skillful at convincing the
animals that Napoleon is utterly selfless; everything he does is supposedly for their benefit,
not his. Just as Napoleon is prepared to make sacrifices for the long-term success of the
Animalist revolution, so too should the animals. That explains why the animals are so ready to
go along with the building of the windmill even though it will involve a lot of hard effort and
fewer rations.
