Let's say WWI comes to happen like OTL, except instead of dragging on for four years, it ends relatively early. Say France falls in 1914, and then Russia sues for peace either that same year or the next. Obviously the war wouldn't have been as bloody as OTL, but does this actually solve any of Europe's problems? Will the tide of socialist revolution be dampened, along with the inevitable reactionary response? Would the national rivalries that consumed the continent for centuries recede? Or is violent, chaotic change still inevitable?
