I will give you just one example of the "power" of TCs.
Before the referendum the leader of TCs was the "president" Denctash, and he was against the Annan plan. Turkey was in favor of the Annan plan. So Turkey decided that the leader of TCs was not the "president" anymore, but the "prime minister" and Denctash after decades of being the leader, he was brushed aside the moment that he lost the support of Turkey.
Can you imagine a foreign country deciding that from today our leader is not our president but the Chairman of the parliament?
Viewpoint and Zan can say whatever they want, the fact remains that the so called "trnc" is nothing more than an illegal puppet state of Turkey and that all important decisions come directly from Ankara and the military generals.
TCs have only one kind of power, and that is to affect the public opinion in Turkey which in turn can affect the results of the Turkish elections.
However Turkey has that covered as well: Every leader of the "trnc" should be pre-aproved by them otherwise he has no chance of getting elected, they brought large numbers of Turkish settlers while at the same time 1000s of TCs emigrated abroad which means that in occupied Cyprus they have the "right kind" of population that wouldn't go against them, the constant brainwashing of TCs during the last 32 years guarantees that very few TCs will ever be able to see that their own interests and well being are actually in conflict with the interests of the Turkish army in Cyprus.
So you honestly think that Tpap negotiates without influence by any other outside interference.
There is a great difference between not being able to enforce your decisions due to the lack of power (what happens to all small countries in their conflicts with the larger ones), and not being able to even take a decision because all important policies come from abroad, which is the case for the pseudo puppet state of Turkey in the occupied areas.
Papadopoulos and the leadership of RoC serve and fight for the interests of Cyprus. On the other hand, any leadership in the so called "trnc" should follow the directions that serve the interests of Turkey in general, and especially the Turkish army, since for Turkey (internally) TCs are considered as a tiny population of a small district and they would never act in a way that would serve the interests of this tiny population and go against their own strategic interests in the area.
