WWI was called the war to end all wars. the challenge with no pod before 11-11-1918 is to create a peace settlement that will prevent all nations who fought in WWI from ever having to fight another nation that fought in WWI
This is virtually impossible.
The treaty of Sevres imposed on the Ottoman Empire pretty much guaranteed a revolution. The Turkish war of independence naturally followed, and by 1922 Ataturk and his supporters had skilfully defeated the Greeks, the French, the British, the Italians, the Kurds and the royalists.
The partition of the Ottoman provinces in the Arab world has pretty much guaranteed constant conflict, strife and war ever since, up to and including the Israel Palestine conflict, the various wars in Iraq, the rise of ISIS and the domination of the house of Saud.
Stopping all that will be very difficult. While some British officials predicted that an overly harsh treaty would be a disaster, the British prime minister was a pro-Greek fanatic and ignored all advice.
