What was the irony in the scene where the animals celebrate after the windmill was blown up?

The irony in the scene where the animals celebrate after the windmill is blown up lies in their misplaced sense of triumph and resilience. Instead of recognizing the destruction as a setback, they choose to celebrate their hard work and collective spirit, demonstrating a willful ignorance of their dire situation. This reflects their manipulation by the pigs, who use Propaganda to twist the narrative, highlighting the tragic disconnect between the animals' reality and their fervent loyalty to a distorted cause. Ultimately, it underscores the theme of how oppressive regimes can exploit hope and camaraderie to maintain control.
