The accession process has been derailed many times in the past
The accession process just started, how could it have been derailed many time in the past?
Every country follows its interests and has a responsibility to ensure the well being of their own citizens only.
The same goes for Cyprus. The veto that Turkey will receive if she doesn't end the illegalities in Cyprus will not be "half" at all.
You are trying to make it appear as if the accession process is critical for Turkey. It is not that critical.
Your opinion. If Turks are happy to remain third world country and make step backwards in this respect then yes, it is not critical. However I don't think many Turks would be happy with such development.
Turkey expereinced many economic crisis before, which although lead to significant hardship for the turkish nation, never endangered its territorial integrity. Turkey has the biggest army in NATO and is capable of defending itself adequately against any internal or external attack.
Many said this before. Does Turkey have more power that the former USSR?
In fact pople in cyprus were slaves before the ottomans came under the feudal system.
Yes, they were before and during the Ottomans. This has been the case with the many nations that the Ottomans oppressed. However those people didn't just accept to remain slaves, they revolted, they fought against the tyrants and finally they were liberated.
If you brag about the power of Turkey today, then imagine how you would brag about the power of the Ottomans compared to their Greek slaves. Yet, that power was not enough for the Turks to force what was obviously unfair.
