We should foster good relations with like-minded nations and not be afraid to admit to ties-that-bind.
I agree with Nikitas that Cyprus is Independent, hence does not need guarantees from anyone as to its right to exist and defend itself from expansionist nations.
Instead those expansionist nations threatening sovereignties should be punished by united organisations like the EU & UN (basically US) and Russia (due to its might) with the whole gamut of weapons available (economic sanctions upwards).
The Treaty of Guarantee over Cyprus was like a slip of paper allowing the bully to do as it liked .... and it did.
Who in their right minds, knowing the nature of the Turk would have handed over such a right to them .... oh yeah! The UK.
The UK is singularly responsible for getting us in this mess with Turkey by handing them a permit, and it should not get off Scot free ....
