Westphalia. The Congress of Vienna. Versailles. Potsdam.  All to draw European borders.

The Berlin Conference to divide Africa. The Sykes–Picot Agreement to divide the Middle East. British India or French Indo-China.

Europeans are very happy to draw borders and force them on others.

Now imagine how different the world might be if the WWI Allies had adhered to the Constantinople Agreement, where Britain and France agreed to hand Constantinople to the Russians!
