....That Turkey threw in her lot with the Axis in WW2.
This was a distinct possibility early in the war as Turkey was very keen to not only get back the Italian held islands of the Dodecanese but also the great swathe of their former Middle Eastern territories - Iraq, Jordan, Lebanon, Syria, Palestine, much of the Arabian Peninsula etc. These had been divided up after the end of the First World War between the British and French under the terms of the Sykes-Picot agreement. See the following for a short introduction - Sykes-Picot Agreement.
With the British and French colonial forces facing a German backed Turkish onslaught (even though Syria fell under Vichy control following the fall of France) I am thinking that there is some entertaining mileage in this from a gaming perspective.
Throw in the Russian Bear lurking in the north with designs on encircling the former 'Sick Man of Europe' and I reckon you have a rich canvas on which to create some varied actions. WW2 Colonial forces, revolting tribesman, sinister Nazis and Reds under the divan should make for an entertaining set up.
One to ponder further methinks....;-)
