I do not know why others rejected the Annan plan, but know why I did.
It was obvious from Erdoghans statements after Burgenstok that Turkey regarded the plan as a mere step in a geopolitical game that was entering a new phase, it was not ending a conflict.. "We got what we wanted without removing a single soldier or returning one inch of territory" this I saw and heard on live TV. This statement colored the type of implementation to be expected from the interim agreements forseen in the Annan plan.
Second and most important part was the cutting of the GC constituent state into two pieces divided by the Dhekelia base. A vital part of the GC state is the eastern part which includes Famagusta. When this part has no guaranteed and GC controlled road links with the rest then the plan sucks. All the provisions of flyovers and underpasses were bullshit, especially in view of Erdoghans statements and the military details of the plan.
Third point was the overly detailed list of armaments that the Turkish generasl laid down for each side during the interim period. Details which gave the Turkish army a crushing firepower advantage. Why was such an advantage deemed necessary when the Turkish air force and air borne troops are two minutes away? Again the question is indirectly answered by Erdoghans statement.
The GC and Greek side wanted an interim arrangement that would have left the UNFICYP as the major military power on the island. This was vehemently rejected by Turkey. Why? Their suspicion of the GCs and Greeks is understandable, but what suspicion could be leveled against Argentinian, Swedes and others who make up the UNFICYP? Obviously none, if there were no ulterior motives.
While promoting "communal equality" the Annan plan specifically excluded ALL other (non Greek non Turkish) Cypriot communities from such equality restricting them to some minor guaranteed representation.
None of the above were mentioned by Papaodpoulos in his emotional pre Easter appeal. None have been mentioned by any GC or Greek politicians before or since. The GC side continues to negotiate like total geopolitical illiterates, and maybe they are. Leaving geopolitical issues open undermines the future harmony between the two communities. That is why I harp on the point so much.
