The island will be permanently militarised as there is no way that the Greek Cypriots will trust the Turks so we will be always on a war alert.
We will never trust Turkey anyways. The difference is that with a good solution or no solution we will at least have the right to defend ourselves, we will have a state that can challenge Turkey when Turkey acts in a hostile to us way, and Turkey will not have any excuses to invade again.
On the other hand with a bad solution we will not have the right to defend ourselves, the TCs will be able to block any attempt to challenge Turkey in EU, UN or anywhere else and, even worst, Turkey through their TC minority will be able to create deadlocks and conflicts, like they did in the 60s.
Actually what you suggested, to accept something unfair and try to change it later, is the excuse that Turkey found to start the conflict in the 60s. So how can you suggest to do the same again?
Any solution today, with the current balance of power, will be a bad solution for us. Thats the bad news.
The good news is that the UN, EU, USA, Russia, China or any country that matters will never recognize the pseudo state and it will remain an illegally occupied part of Republic of Cyprus.
The other good news is that Turkey is a very unstable country, torn between east and west and a clear direction, with a big Kurdish minority that sits on a lot of oil, and an arrogance which inevitably will cost them dearly.
Write this down and remember me when I say that the balance of power will not always favor Turkey, and that within our lifetimes we will see it shift. I believe that in the long run a smaller, weaker and more manageable Turkey will become a necessity for those that have the power to enforce this. The fact that the Kurds sit on a lot of oil and are willing to fight for their lands when supplied with weapons and support will make this split much easier (for the outsiders).
When the balance of power will change, then we can take back our lands and implement a normal democratic system in Cyprus. And please don't tell me that if we don't rush for a solution now partition will be "cemented". These are just threats to scare the naive. If Turks today are trying to illegally undo 3500 years of Greek Cypriot history, then be sure it will be very easy to undo 50 or 60 years of illegalities when we will have every right to do so.
