If Kerensky had been successful maybe Russia would have ended up with a Nordic democratic socialism model. Not that he had the wherewithal to be successful ( Ordered an ill-fated military offensive against Austro-Hungarian forces in June/July 1917 that resulted in heavy losses damaged him politically), but there was a brief shining moment prior to the Germans injecting Lenin back into Russia. The German gambit that sending Lenin into Russia would take Russia out of the war paid off much more handsomely than they could've imagined.
