(it still shocks me that the annan retard plan absolved turkey of all blame)
The AP was a settlement plan it was not a court or tribunal. Its purpose was to present a negotiated and compromised agreement, addressing as many legitimate interests as possible, and subject to a referendum. It never was its purpose to determine "blame" (whatever that might be).
That many people voted against it could be because (i) they didn't think that the broad plan was right, or (ii) that they didn't think particular interests had been properly represented, or that (iii) they disputed who had a "legitimate" interest, or (iv) a combination of the above. At no point did the AP claim to deal with "blame".
