But imagine how different things would have been if the fight between Germany/Austria-Hungary and Russia would have been localized in 1914. Should have just let those three beat each other up and stand back and munch on the popcorn.
But because France was allied with Russia, the Germans felt they had to neutralize France first, to free them up to attack Russia.
Which now meant the Germans had to go through Belgium, which then pulled the Brits into the war......and of course, once Britain was in it, it was only a matter of time before the US would get dragged into it.

It would be impossible. Because Germany had more interests on west of her than on east. And they knew the lesson of Napoleon. You may even get to Moscow BUT it will NOT help you to win. It was proved again in 1941.
And you must bring all your troops there and it will not be enough.
SO when Germany and Austria inevitably stick in a vast forests of Russia they would be attacked into their backs by same France and UK. And they would have a war on 2 fronts which they lose.
SO Germany and Austria realized and never wanted this.
