Why was the soviet union so popular when orwell wrote animal farm?

stalin ordered the assassination of hitler.
the red army defeated the german army.
trotsky and lenin were ambassadors to england.
hitler agreed to peace negotiations with the communist party.

The correct answer is "The Red Army defeated the German army". When Orwell wrote "Animal Farm" to be later published in 1945, the Soviet Union was popular around the world because they achieved to defeat the German army during World War II in that same year. These two events are related as "Animal Farm" described much of the events that led to Russian Revolution of 1917.
