I think that history will show Denktash to have been one of the cleverest Cypriot politicians ever.
By opening the "border" he allowed the TC the chance of wealth they could never of dreamed of, probably more than many will have the chance of on the Turkish mainland.
He also put the Greek Cypriot side firmly on their back foot, to maintain the principle of a united people of Cyprus they have to allow TCs to come to the government controlled areas for work, (in the Famagusta areas this is a real problem, I've got relatives who can't get work on the constrution sites as all jobs are taken by TCs), to travel, sometimes there are as many TC taxi drivers at Larnaca as GCs, and to use the public health service, which I believe is costing a great deal, and stretching the resources of the system.
On top of that there are the casinos and cabarets which are taking a fortune from the GCs.
However, since the "border" opened the greatest source of revenue for the TC area (I'm not sure how this has worked it's way into the ordinary TC pocket though) has been the massive increase in property sales, having the border open has given land sales in the North a lot of credibility with foreigners ignorant of the legal situation, I've spoken to people who've bought land noth of Famagusta who've said that "it's OK now the border's open" !(BTW, they don't use " Quotation Marks" when refering to the "border").
It seems to me, and I make money taking tourists up to the TC controlled areas, there are far more TCs coming to the South than GCs going to the North now, and that the GC are getting well and truly screwed everyday the checkpoints are open!
So.....WHY keep it open?... WHY not close it?
