Essentially, is it possible for WW1 to end similarly to how another great war, the 7 Year's War in Europe, ended, without any significant territorial, political or economic shifts, with all the empires remaining essentially intact and keeping the same system of alliances, only at peace?
The Seven Years War ended as
status quo ante in Europe because Britain had got everything it wanted outside Europe, and left Prussia in the lurch. Then Russia (which had no real interests in the war) bailed out, and Fritz fought the Austrians and French to a draw.
In WW I, Germany's colonies are nearly worthless, and no one is settling for that. The war in Europe continues to decision.
Possibility.
1) The messenger with the withdraw order doesn't reach Von Kluck's HQ. German 1st Army is cut off and destroyed. The Western Front is bent well east; the Allies hold Antwerp and regain Brussels.
2) Better Russian commanders and worse German commanders in Prussia. The Russians occupy most of East Prussia and besiege Konigsberg.
3)
Goeben is intercepted and flees to Austria instead of Turkey. Turkey remains neutral.
4) Haber blows up a retort, and doesn't get his process going. Germany is out of nitrates by the end of 1914.
5) As OTL, Russia defeats Austria in Galicia, and Serbia repulses Austrian invasion.
At this point, the German war policy has failed on all fronts. So has Austria's. The CPs are barely holding on. Italy is rumored to be going to war against Austria, so is Romania. Austria is threatening to bail out at once; Germany has no choice but to make peace.
OTOH, the Allies have taken a lot of hits, and could be persuaded to end the war ASAP. France wants Alsace-Lorraine back, but Germany's not going there and Britain won't fight for years to make her.
The Kaiser and some of the generals insist that
Germany must triumph, but cooler heads arrange a quiet palace coup; Willy has a "breakdown" and abdicates. Russia is bought off with eastern Galicia, Britain with colonies, France with reparations, Belgium with the heads of a few "war criminals".
Aside from Galicia, no territorial changes in Europe.
