Here you can see the natural borders of the Byzantine empire, which was populated by Roman and Greek People of Color (their particular color: kind of olive-pinkish):
Since then, the white (they only look brown because they live in a desert) Turkish and Arab Muslim invaders have instituted racist apartheid settler colonialism against the indigenous Greek, Roman, Armenian and Assyrian People of Color.
There is only one solution to this: The white supremacist Arab-Turkish Islamic settler colonialist project has to be dismantled, allowing indigenous Christians to repopulate their countries of origin.
The white Arab invaders should return to their own homeland: The Arab peninsula. Only Coptic Christians can remain in Egypt, only Marionite Phoenicians can remain in Lebanon, only the Hebrews should remain in Palestine.
Just because all of this happened in the early medieval era, does not mean that indigenous Christians and Hebrews have lost their right to their homeland.
