Wars are won through sacrifice. I certainly agree.
But on numbers alone the Soviets union should have kicked Nazi arse before Moscow was threatened.
The Germans proved what many had thought incorrect until WWI: technology, supplies and experience beat manpower.
It's why there's no path to victory for North Korea. I wouldn't be surprised if their generals knew it too.
The Soviets sacrificed, not because of love of the motherland, but because of threat of German enslavement or the threat of a Russian firing squad.
Russia sacrificed because they had no supplies, no technology and the only thing they could do to slow the German advance was send men out into the battlefield without bullets or guns.
I'll get you sources when I'm not mobile.
But just to this point, there are still persistent rumours that some Russian soldiers rebelled on the retreat to Stalingrad. As punishment, their commanding officer instituted десятник - the ancient Roman practice of decimation.

I'm in IT dude. This is disaster week. WannaCry mitigation for all my clients..
Maybe you need some lend-lease assistance with fighting that front?
Don't need to justify - just wanted to remind.
Anyway back to the original topic - I think there's a level of pragmatism in North Korea's strategies that is often overlooked.
