I would agree that the British government would not give back Egypt and unless the Germans did something it would be doubtful that they would get Cyprus either. The Ottoman's were the weakest of the Central Powers.
I respectfully decline to rise to the bait.
If the CP won, Britain might be inclined to return Cyprus if it avoided having to give up something more important in exchange - if they lose Egypt, it has little value, and if they retain Egypt, it still has little value.
The Ottomans would be more interested in Caucasian territory, which they occupied by themselves in OTL - and are unlikely to give up if the CP win. As for Central Asia, if Russia has collapsed as per OTL, a victorious Ottoman Empire is likely to get involved there, and is also likely to have a pretty large impact. In OTL, Enver Pasha went there all by himself and nearly conquered the region - with a veteran division...
Also, the Reds were able to use as mercenaries a large proportion of the fairly large number of Austro-Hungarian POW's housed in Central Asia. In a CP-victorious scenario, those will be on the opposite side, most likely.
