What blatant lie about the animals sole wish now and in the past does Napoleon make in his speech?

In his speech, Napoleon asserts that the animals' sole wish has always been to serve the needs of the farm and its leadership. This is a blatant lie, as the animals initially aspired for freedom and equality, seeking to overthrow their oppressive human owner. Napoleon's manipulation of their desires serves to justify his authoritarian rule and stifle dissent, distorting their true motivations and aspirations.
