Lore
The notable point of divergence from our history is that Germany refused to use unrestricted submarine warfare after the sinking of Lusitania in 1915, and British submarines sank a US ship taking Christmas supplies to Germany. This leads to the US never entering the war, and the blockade being lifted on Germany. Allowing Germany to force France into defeat by 1919 (through a combination of CGT-led strikes, mutinies and military defeats) and eventually end the war in 1922.
In Russia, German intervention in the Russian Civil War destroys the Black Army and Free Territory in Ukraine and ultimately captures Moscow, defeating Trotsky (Lenin had been assassinated in 1918 by Fanny Kaplan)
