Lilia Efimova observes that the War that's being commemorated on the TV is not quite the war the Russians remember.
Some of this, of course, is dealing with Stalin.
But Americans (and, I think, lots of Western Europeans) tend to forget how central the Soviets were to winning the war. They won; we helped.
Could we have done it without the Soviets? Maybe. Fortunately, we didn't have to find out.
