The Soviets trained German pilots and developed their planes for them in secret so Germany wouldn’t be caught violating the Versailles Treaty (that is why some Soviet planes bear a striking resemblance to some German ones). The USSR invaded half of Poland (AND THE BALTIC STATES) in 1939 when Germany invaded the other half, killed thousands of Polish officers in Katyn, and was spared a declaration of war by Britain and France. In 1940 they attacked Finland and seized part of their country. Prior to that they had murdered millions in the Ukraine; after that they armed Red China, North Korea, Vietnam, Cuba, Angola, etc.. They only survived WWII because we armed and supplied them - and they maintained a truce with Japan in the Far East while Japs were killing Americans, Brits, Chinese, Filipinos, etc..
Sorry, we don’t owe “the Russians” anything; too bad the USSR survived.
People I respect here are making important arguments... I was thinking more of ‘the Russian people’ but they DID choose their leaders... so I’m probably wrong on this issue. The old USSR was a totalitarian hellhole... and that’s worth remembering.
