Yes, but, regardless, comparing the sacrifices Russia made in the fight against the Axis Powers to the sacrifices the U.S. made is like comparing a tank to a Styrofoam cup.
If your implication was that the Soviet Union should somehow give America some of the credit for Allied success on the Eastern Front, then I reject your argument. Just because your Mom buys you football cleats, doesn't mean you should give her credit for winning the game for you. Should you thank her? Yes. Did she do any of the actual work that went into the victory? No.
Yes, but when mom not only bought your cleats, but also the shoulder pads, jerseys, footballs for the entire team, and then gave you scouting on the opponent, then you can indeed credit her with a portion of the victory.
I'm not saying the Russian's don't deserve credit, but I think it is fair to say that it would have gone differently if we hadn't given them tanks, planes, and jeeps, along with artillery, munitions, rifle, food, clothes...
