The Turkish military nearly overthrew their own gov't recently. They could snap their fingers instantly and the current gov't in North Cyprus would collapse overnight.
Just last week there was a controversy in which the north's PM had promised pilgrims they could visit a church in the north. Much to his embarrassment and chagrin, the military prevented the visit, this despite the fact the border crossings had been open for months.
The Cyprus problem won't be solved until Turkey is on the doorstep of the EU. I read the Turkish papers everyday, and everyone considers Cyprus a great card for Turkey to play in negotiations with the EU.
Finally, the events in Kosovo and Georgia give the TRNC hope.
