Wilson’s hand was forced by the belief that unrestricted submarine warfare was going to starve Britain out of the war. We see that Russia was totally defeated. France could not have lasted alone against Germany. The war would have ended with Germany dominating Europe and Lenin and Stalin ruling the USSR. A German-Soviet war would have been inevitable.
Your historical guess is bunk!
1) Germany dominating Europe would have sunk the communist revolution in Russia period. Example of Soviets weakness: Polish–Russian War of 1919–1921 where little Poland kicked the Soviets a$$! With Germany dominating and with, German eastern borders at least equivalent to those of 1914, there would have been German troops (best combat troops of either war) right on the boarder of Russia. There is no way Germany would have allow the Soviets any breathing space to form an anti - monarchy government. Remember Kaiser Wilhelm was the cousin of Czar Nicholas. There would have been hell to pay for the commies that shot the Czar and family, you can bet on that!
2) With the Soviets cowed there would have been no Stalin to lead a communist government. Additionally, there would be no Hitler nazi government. Kaiser Wilhelm would have been seen as one of the greatest German leaders in history. There would not have been room for a Hitler or his thurst for revenge.
3) The prospect of a German-Soviet war might be somewhat valid. If war against the Soviets had happened:
a) Germany dominating Europe
b) war reparations from the allies
c) no allied sea blockade
d) European anti communist allies
e) the entire German army available to fight against the Soviets.
All this would have insured a complete Soviet defeat.
