Pirates,you are kind to suggest TCs are 18 per cent of the population.That was in 1960
Yes, I assume that a number of TCs will return to Cyprus (this will be the case with GCs also) after a solution and that inevitably some Turkish settlers will get the Cypriot citizenship. This is why I say 18%.
In general I agree with you. The 1960 agreements were far from perfect. However it is the only thing agreed so far and it was a compromise from both sides. Expecting that one side will compromise on top of the compromise is unfair. Today is not 1960, but 2005. In the 60s RoC didn't work as it should because GCs didn't care for it (they wanted union with Greece) and TCs didn't care for it either (they wanted partition). I believe that if both sides decide to make the 1960 agreements to work today that this is very possible.
Unfortunately all those settlers that you mentioned above are "TRNC" voters. So Talad and the other TC leaders have to serve their interests also (since without their votes they can not be elected). If you add to that the power of the Turkish army over the TC politicians, then you can see that even if TCs wanted to make such a step they wouldn't be allowed to do it anyways.
