>the German army fought through 3 winters

That's true, but the winter was famously the inflection point in WWII. It's no coincidence.

All the sources I've read agree that this had more to do with the complete absence of a long term strategy on the German side, not the weather. They had resources for 6 months, and went into the USSR with everything they had, no reserves. When that wasn't enough, there was no plan B.

Interesting. I'll have to explore this explanation further sometime.
