Which brings me to another question. When the Ottoman Empire was defeated after World War I, why wasn't Constantinople given to the Greeks?
Because when the Greeks, after the war, aided by the French and the Italians, tried to take it, Ataturk and the Turks gave them a pretty sound thrashing.
The French already had gotten Syria and Lebanon. The Italians already held the Dodecanes Islands and Libya as the reult of their successful 1911 War against the Turks. (as were the Serbs and Montenegrins in the Balkan wars of Independence from Turkey.
