Look, it's not expelling some imperial troops. but peaceful citizens, who sometimes had lived there for centuries.
The idea that people of different ethnicities live, unmixed, divided by neat borders of nation-states is pretty recent. This was the case neither in Europe, nor in Middle East for a very long time before the advent of state-based nationalism in the 19th century. It was quite normal for people of different ethnicities, languages, and even faiths to live intermixed in certain regions, especially areas of intense trade, which the entire Mediterranean coast used to be. Borders were more about economic and political control than ethnic identity.
(The ethnic unity purportedly achieved by nation-states formed in 19th and early 20th centuries is also often more by fiat: look at the variety of German or Italian languages prior to unification of Germany or Italy, for instance, to say nothing about India.)
