Small but important detail about "retaliating" against Cyprus by recognising the TRNC- to do so would recognise and approve the expropriation of properties belonging to EU citizens, it would also involve flouting UN resolutions and decisions of the ECHR, the EUROPEAN court of human rights. It would also be the death knell for Turkey's EU membership as not only Cyprus but other countries in the EU would used such recognition to stop Turkey's progress dead in its tracks directly and indirctely by bringing up the Kurdish and other issues.
Utu, you are confusing the lifting of "isolations" as recognition, and the two are not the same.
As for Kosovo the majority of the inhabitants are Albanians, who have not expropriated anyone's land and the recognition is conditional on the human rights of the non Albanians being protected.
