The scenes in 1984 where the speaker ranting against Eurasia getting a note and without missing a beat switched to ranting against Eastasia was Orwell satirizing the British communists switching between loving fascism to hating it when Hitler betrayed Stalin. They pretended that 1939 to 1941 never existed.
It shouldn't be surprising since Mussolini was the editor of the Italian Socialist party newspaper before he left/was ejected for disagreeing with the party's pacifism in WW1 and formed the Fascist Party. Fascists and communists are jackals from the same evil litter, snapping at each other but largely indistinguishable to outsiders.
As my PolySci professor said....”The only thing that separates Communists from the Nazis is 5 letters. I-n-t-e-r. National Socialists vs International Socialists.”
Two sides of the same coin.
Fascism and communism both have the same goal: totalitarian control...............
