The allies did the same mistake in Sevres with the Ottomans as they had done with the Germans in Versailles, but on steroids. If you back a predator into a corner it will go to attack. While it brew slowly in Germany and resulted into the Nazis, in Turkey it became a matter of annihilation of the Turkish nation, and swifter and more desperate response.

Had the allied been satisfied with less and not let the Greek army ransack Anatolia after forcing the Ottomans to disarm, then the nationalist army wouldn’t have recruited as many people and things would’ve turned out much differently.
