"He who does not think himself worth saving from poverty and ignorance by his own efforts, will hardly be thought worth the efforts of anybody else." -- Frederick Douglass, Self-Made Men (1872)
Had Germany been able to call up another 100K men and not had them fighting the US in France. Russia very well may be part of Germany to this day.
And I agree, the US and its allies would have had a much harder time beating the Germans back to Germany had they not been tied up in Russia.
The allies were very lucky that Germany could not recall what was left of its army in Russia in time to fight them.
Luck played a huge part in all of the war. On both sides.
But if you want to stick to the "Russia won the war", knock yourself out.
