Hmm. It wouldn't be difficult to eliminate the Bolshevik revolution and I suspect a weak central government would eventually have to make peace, especially if the Kerensky offensive failed as badly as OTL and led to the July Days. Maybe Kerensky and Kornilov ally fully and eliminate the Bolshevisk, rather than Kerensky supplying them with arms. Or Kornilov stages a successful coup, though this would probably prolong Russian involvement in the Great War. Or Kerensky successfully uses the whole plot as a device to boost his popularity and marginalise the Bolsheviks.
Let's take the option that the Kerensky offensive is a worse disaster but he manages to maintain his own power and eliminate the Reds. This means Russia will cede a lot of territory to Germany (and probably some to the Ottomans and AH). This might lead to a CP victory, or not. Either way Russia is likely to be riven with internal unrest for years to come, with various warlord states persisting (see '
Ephemeral States of the Russian Civil War') and maybe Roman von Ungern-Sternberg establishing a dynasty in Mongolia.
There will be no Stalinist forced-draught industrialistion, until perhaps the government is toppled during the Big Slump and replaced bya himegrown political cult espousing a windy mix of nationalism, monarchism, corporatism, anti-liberalism, anti-socialism, social conservatism, Pan-Slavism, reactionary (Orthodox) Christianity and tinges of anti-Semitism and xenophobia.Then the stage is set for the Great Eastern War of 1941-46...
OK, maybe not. But without the Russian/Soviet example the 'Red Scare' would be far less, probably benefiting various socialist/social-democrat groups (and respect for civil liberties, I'm looking at you Palmer). An earlier and more stable Labour government in Britain perhaps?
