That is correct,
The only way the TC's could achieve a state in Cyprus was through ethnic cleansing, which is illegal and theft of a part of someone else's country.
You cant say on the one hand, that you are Cypriot and Cyprus is your country pre 1960. Then post 1974, only the northern third of Cyprus is, which was 80% GC pre 1974.
Taking in to account the fact that no one, except Turkey recongises the "TURKISH republic in the north of Cyprus" further proves that the TC were not and are not entitled to their own state.
This artificial illegal state is now majority Turkish through the illegal transfer or Turks from Turkey. Therefor, it is not Cypriot.
Furthermore, why would Mak agree to giving a 50% veto to 18% of the population against the remaining 82% as well as 30% of anything financially related when previously he wanted enosis. He wouldnt't willingly, unless he was under duress. Which then makes the 1960's agreements legally invalid. This is why he proposed the 13 points to amend it because for 3 years, the TC were abusing the population and the state and the country was heading towards a civil war.
