I personally think that the Greek-Turkish conflict in Cyprus in the 1970s was a mistake, but we can’t change the past. The fact of the matter is that a clear majority of Turkish Cypriots alive today were born in Turkish Cyprus, so they have just as much of a right to live there as native Greek Cypriots do. Imo, the anti-Turkish Cyprus stuff is one of the least convincing arguments from the pro-Republic of Cyprus crowd for this reason. It’s not much different from arguing that Native Americans would be morally justified in forcibly removing white people from America.
The fact of the matter is that pretty much every Israeli alive today was born in the Israel/Palestine region, so they have just as much of a right to live there as native Palestinians do.
Was reading up on aliyah last night actually. The number of people born in the Soviet Union now living in Israel is so great that Russian is a working language of sorts in the state behind Hebrew and Arabic with public broadcasting. Using from 1980 onwards as my cutoff date, historical data in a table on the subject of aliyah on Wikipedia says about 1.6 million people immigrated to Israel from abroad. The 2022 estimate for national population is 9.6 million, so if all those people are still alive we're talking 1 out of 6.
