Hi Aidan.
I think we are running around in a circle with the British bases issue. May I suggest that my final answer on that subject consist of the latest opinion survey conducted on the island where the majority Greek Cypriot population agree that the bases are disputed. We do have a problem with them embedded in the Cyprus republic, and that their use has long expired. We also believe that Turkey poses no real threat as it would be very stupied to act like Iran on Cypriot sole in this day and age, further cementing the removal of the British bases, and that Turkey's EU wish has placed the Cyprus government in a very unique advantagous situation in front of Turkey.
I believe that the British bases are a combination of secret British dealings, and are very symbolic only for the British - nothing more. And, in real terms, the two British bases in an all out war with Iran (as I believe you may have been suggesting) would probably pose Cyprus under threat rather than assist its foreign policy to the OIC and other muslim nations. Although the Cyprus government may no presently see eye-to-eye with Iran due to obvious reason, it certainly respects the wishes of the OIC and works very well with all of the nations that surround it.
Also, I honestly believe that the British bases can not be a part of a new Cyprus unified state - especially a bi-communal structure sensitive on land allocation and "Military" ventures of others. Please, let's be realistic here! British rights under the 1959 agreements must also be ammended under a new unification agreement, and I do not see Britain being able to finally convince the Cypriots otherwise.
