Responding to an assertion by Gerald Knaus…

Athens and Skopje face a [prisoner's dilemma]: if neither side believes that a solution is possible, and acts on this, both will lose.

Zarko Trajanoski wrote on Facebook:

However, the analogy with “prisoner's dilemma” is not only false, but very offensive: Athens is not a prisoner, but a prison guard and perhaps a political torturer in this case. And the outcome of this political torture, aided by Sofia as well, is the rise of the Macedonian ethno-nationalism and the decline of the liberalism, democracy and human rights.

He later provided an elaborate explanation in a blog post [mk].
