Reunification will always fail primarily for the below reasons:
(1) The Greek Cypriots strongly object to the dissolution of the Republic of Cyprus
(2) The Turkish Cypriots believe that the current "Republic of Cyprus" can not continue in a new Comprehensive settlement based on a Federal basis
(3) The Greek Cypriots entered the EU as the "Republic of Cyprus" under their own terms without the consent or, advice even, of the Turkish Cypriots
(4) The "Republic of Cyprus" today resembles nothing of the original "Cyprus Republic" of 1959/60...No Zurich Agreements and etc!
(5) The 13-point changes the Greek Cypriot fought for in 1963/4 and now include in today's "Republic of Cyprus" without the permission of the Turkish Cypriots
(6) "Reunification" can not be, neither the TRNC or the GC-ROC, but a completely NEW platform of two Federated states under One Confederal Government
(7) "Unification" is a term concerning Cyprus that incorporate the Turkish Cypriots as another "Minority" community, deeming a resolution impossible!
(8) The Greek and Turkish Cypriots are "Partner" people of the Original Cyprus Republic - not to be forgotten please!
(9) The Cyprus problem can never be resolved without both signatures (as previously stated in another post)
(10) There is NO COMMON SINGLE Language in Cyprus, unless the Greek Cypriots will accept it to be the English Language.
(11) A Comprehensive Federal agreement is only discussed by Cypriots only, thus a formula for disaster as they can't even agree a Meeting let alone a settlement.
(12) The Turkish Cypriot NORTH (TRNC) has this week started to sway from such an agreement and has commenced its Plan-B already....http://www.lgcnews.com/islamic-bank-15-million-dollar-deal-tc-chamber-commerce/ - http://en.wikipedia.org/wiki/Member_states_of_the_Organisation_of_Islamic_Cooperation - is a good example of this.
Finally, on the issue of Territory/adjustment, the Greek Cypriots wage their reasons on larger territory based on their population, where the world clearly does not operate this way otherwise Greece (with its tiny 10million people) could easily fit into Athens alone and the rest of their land would have been shared between Turkey and Italy (having much larger populations). Hence, why the territory Greek Cypriot constant bashing of their argument doesn't make much sense at the UN Table!
