The likeliest event would have been the Brit's still fighting Germany to a standstill in France until the U.S. forces hit like a ton of bricks. In other words, had the Germans won at the Somne, WW I would then be more like WW II, although maybe without a Dunkirk.

That is assuming that the US would participate in the war.
The US only joined the war in 1917. If Fukuyama is right there might not have been a war in 1917.
