I think of Progress as something like "things are getting worse and worse" or "things are getting better and better" -- not "nothing has changed." I realize I might be contradicting myself here from my earlier statement that they want to "shake things loose" but the feeling to me is really about hearkening back to something that's been lost.
I do see an element of that in the (possibly misleading?) title of the book which suggests the problem of a city that's eroding over time. But I think the really haunting thing about Varosha isn't just that it's slowly disappearing (though it is that), it's that it was abandoned at a moment in time -- frozen, so to speak (though of course worn away by the passing years).
It's also a very Greek thing--the problem of the modern Greek being this perception of this immense, great Past that they can't live up to or live down. This is what they're going for when they name the secret society after the "heroes" of the Greek revolution.
Meanwhile, the Turkish Cypriots point to the violence against them in the 1960s as justification for the invasion of '74 and they call it a "peace operation". If you ever get on an Internet forum in which Greek and Turkish Cypriots are arguing (don't, it's not worth it) you'll see these arguments about what actually happened and who is rewriting the history being rehashed over and over again.
I could imagine a story that deals with the periodic restarting of peace negotiations between the two sides. These negotiations are always about Progress -- are we going to make Progress this time? Is all this Progress they claim they're making BS because they haven't dealt with the real issues? Is all our Progress toward a solution going to be tossed away because of the interests of some foreign power?
But I don't think that's what this story was about.
However I could be wrong! And here I go bringing in material that wasn't in the text.
I'd be very interested to hear what others think.
EDIT: I just realized you might not be saying the Goal should be in Progress but that we need to articulate the Past better...
