Does an early peace mean there is no Russian Revolution?
Short answerNo. This branch retains a non-Bolshevik revolution but makes the October takeover less likely after peace, renewed food supplies, and a victory the government can claim.
NotesThe distinction is between a revolution and the later Bolshevik seizure of power. In the proposed April 1917 peace, renewed trade and food deliveries strengthen the government described here as Menshevik. A victorious settlement also gives it a political achievement to defend. A constitutional monarchy remains one possible outcome within this counterfactual.
