It all started to fall apart when Bulgaria dropped out of the war and its Tsar abdicated in August 1916. Romania joined the Entente and pushed into Transylvania. With the Russian capture of budapest A/H collapsed and the new nations of Eastern Europe (Poland, Hungary, and Czechoslovakia) joined the Entente. As the British pushed into the Sinai and isolated Wilhelmshaven the French army (new motorized) captured Munich. A Berlin mob, desperate to stop the slaughter, stormed the Kaiserbunker and Wilhem I was barely able to flee before he abdicated and made it to the Netherlands. An attempted Bolshevik coup in Germany was swiftly crushed by Entente troops.
The Allied victory and total destruction of A/H and German led to a revival of the Triumphalist School of British poetry led by Wilfred Owen and the famous line from his poem "what passing bells for victory in battle." France and the new small countries of central Europe began to warily eye the new Russian colossus that lay astride a prostrate Central Europe. Meanwhile, in Germany, with militarism destroyed and the entire country under occupation by one power or another a strong sense of pacifism took hold led by Ernst Junger and his scalding anti-war memoir "Storm of Sorrow." The US, happy to have avoided the entire ruckus and fat from fulfilling large Entente war contracts stayed focused on its own internal development. The Young Turks, the only member of the Central Powers that maintained it's boarders, kept a tight grip on Anatolia, Syria, and Iraq.
