OT History "What If" Discussion: Germany Wins WWI in 1914

Been a while since we've had one of these so I figured my favorite topic from history (WWI) would be a good subject to bring up.

As we all know WWI saw the Allies (US, GB, France, & Italy + others) defeat the Central Powers (German, Austria-Hungary, Ottoman Empire, & Bulgaria). The rest as they say is "history".

But it was a pretty near run thing, especially in the early weeks of the war. Germany could have won in the war quickly (as per the Schlieffen Plan) and then turned her full attention east to deal with Russia which would have not been ready for the full might of both Germany and Austria-Hungary combined. The one thing that stopped Germany in it's tracks, saving France and not allowing Germany to focus on Russia before it could complete it's mobilization, was the First Battle of the Marne ( AKA Miracle On The Marne). But even here, as so often is the case in history, the whole affair came down to one pivotal moment, one decision. In this case it was when German General Alexander Von Kluck turned his 1st Army to face the French along the River Aisne, thus opening a gap between his army and that of Von Bulow's 2nd Army. This is what allowed the French & Brits to halt the German offensive and thus seal Germany's fate which would come a little over 4 years later.

But what if Von Kluck had not made this mistake? Which this mistake was not entirely on him to be fair. What if the "Miracle on the Marne had never happened? What if the Germans had followed Count Alfred von Schlieffen's dying words of "remember to keep the right flank strong" and thus defeated the French & Brits in the summer of 1914? What would our world look like today?
