'Major turning point' really? Why is the US always so desperately trying to convince the world they did free the world? Where was Hitlers army? Where the hardened Wehrmacht and SS? Western Europe was used to rest the sickened and tired troops. The real battle was in eastern part. Where millions where fighting each other.

You could say it has helped a lot, oh yes.. But like with Napoleon, the Russians would have come to the Atlantic to free us..

Hitlers army was a considerable fighting machine and although I am not pro-russian atm, these people did the tremendous job..

Read only War's Unwomanly Face from Svetlana Alexievich. They where going through hell and beyond. And they had their reasons. It's always good to fight for a reason. Just take a look at the ongoing dispute in Ukrain.
