The war didn’t start turning around for the Russians until the end of 43 and ‘44 after the Allies opened The Second Front. We did more then ‘some Lend/lease’’ to the Russians. To say otherwise is to totally ignore the convoys to Murmansk aka “The Atlantic Convoys’’. The Russians did not posses a strategic air force that pounded German war industries and populations centers as the Allies did. Neither did they have a navy that destroyed the German U boat threat in the Atlantic and put the Imperial Japanese navy at the bottom of the Pacific.
That is perspective.
Also, the Soviets loved the Nazis, before they hated them. Two peas in a pod.
