What if Makarios III had been able to prevent or crush the 1974 Cypriot coup d'état by the EOKA-B that led to the Turkish invasion of Cyprus and the Cyprus dispute? What would the Cyprus of this timeline look like?
Well the Turkish invasion would probably not happen but ethnic tensions would certainly rise again, and depending on how things look Athens and Ankara, either of them might do something stupid. Also the junta in Athens probably buy some time by not having the Cyprus fiasco.
