Why does the Party never acknowledge when it changes from fi ghting Eurasia to Eastasia?

Answer 1

"The Party never ackknowledges this because if they do they will seem wrong and the Party's main job is to convince people that they are always right, so to stop this they change the past to say that it was always fighting eastasia"

Answer 2

The Party never acknowledges changing enemies to maintain control over the population through manipulation of information and Propaganda. By keeping the population in a constant state of fear and war, the Party can ensure obedience and divert attention from its oppressive actions. Admitting such changes would undermine the Party's credibility and control.
