Alexander Kerensky takes Russia out of the war before Lenin gets into power, negotiates as white a peace as possible with Germany, and the Germans gain the manpower needed to exploit the collapse of the French mutinies at a time before the Allies amassed the kind of offensive doctrine that led to their OTL victory.
For the most part, the French units which mutinied did not throw down their arms and refuse to fight altogether. They simply refused to attack. Had the Germans mounted a major offensive in late 1917, I think the French soldiers would have resisted as strongly as they did throughout the war.
