What is null and void is your "TRNC". What you have is just 40.000 Turkish troops that prevent legality to be applied in the whole island.
Its called Reality, face it and deal with it, the TRNC can be viewed as many things but in reality it exists and will exist until you guys really want a solution or recognized partition. We can stay like this until the power swings in your favour as you say...so start to adopt a more flexible and compromising attitude otherwise nothing will change.
