Germany would replace OTL RUssia, I don't doubt they would have around the same population, +-145 million
if the americans do not join the war, then the german americans wouldn't be forced to integrated on american culture, we could see a huge amount of german influence in the US, even cities with german names
The german army could also replace the OTL Russian army, with germany having all the resources of central europe, every army in the world would want to look like the Heer, if the germans continue their cooperation with china and the nationalists win the war, the german bloc would be stronger than NATO is today. The Kaiserreich would control the grain of ukraine, the oil of romania, hungary and austria, and depending of the scenarios, the oil of Nigeria too.
