Most likely at least, Communism never would have happened.
Sure it would have. Losing the war was what made Russia ripe for conquest by the commies. Germany made a treaty with the commies (Brest-Litovsk) so they could concentrate all their energies on the western front. Had the Allies defeated the Central Powers sooner, it might have save the Tsar's fragile government. But a German victory would have done nothing to stem the growth of communism in Russia. The treaty with the commies essentially meant the the Germans did win, at least on the eastern front.
True, the trigger mechanism for communism in Russia and later NAZIsm in Germany was the burden placed on the populance by the prolonged war and resultant retributions of the allies.
“Most likely at least, Communism never would have happened.”
Communism was alive and active in the US long before WWI.
