There are no immigrants. There are illegal settlers.
I suppose I am suggesting compensation will be the only answer
I agree. Turkey should compensate the people that they brought here to return to their country.
Because you will not be able to move these people en masse
In 1974 200,000 moved en masse within 2 weeks. If the legal owners could be moved en masse from their own homes, then the illegal settlers can be moved just as easily if the balance of power will allow it. (if = when ... because nothing remains constant)
