Latvia is a small country of about 2 million people. It was part of the USSR superpower from 1940 until 1991. It has a 30% Russian minority and shares borders with Russia.
in 1991, Latvia did not become a great power, it is a small weak country as always. Russia did not become weak either. It is still a vast country with a great army, nuclear weapons etc.
Still, Latvia has managed to gain its independence. What it took was a change in the overall balance of power in the world.
If former USSR was unstable once, Turkey is 100 times as much. Republic of Cyprus should be preparing for the time that will reclaim its own land back and should not sign away anything.
It took for Latvia 51 years. for Cyprus it might take 50, 70 or 100. What is sure is that the balance of power will change and that we should be prepared to take advantage of it.
We tried negotiations and all that. It is now proven that no invader will abandon the land it took by war just because they were convinced from our right and just arguments.
