Britain was never the focus. Destroying communism and communists was. After victory in Europe was secured, Soviet soldiers raped, murdered and pillaged all across the Eastern European nations they 'liberated'. Those in Germany, Poland, Lithuania, Estonia, Latvia and Ukraine all suffered at the hands of their 'liberators' for many decades to come, and the Russians continued to be a blight on peace in Europe and the world to ensure their politics came out on top.
You seem to have forgotten that Poland fell to a dual attack by both the Nazi's AND the Soviets in 1939. Some 'saviors'. Had the British and Americans not opened up another front in Europe and North Africa, Soviet Russia would easily have fallen without Germany having to devote so much effort, troops and attention to North Africa, Sicily and eventually France. The Allies saved the Soviets, not the other way around, and then they tagged along for the victory parade. The Soviets didn't help Britain in those first 3 years either.
But yeah, sure, you go ahead and praise the rapists and violent aggressors, but don't dare assume that people who don't agree with you aren't informed, just because you hold the opinion that the Soviet Union was saintly during WWII.
