OK you guarantee-obsessed Cyprus Turks who need to feel safe. Let's see how commited you are to this "guarantee" premise.
What if free Cypriots insist on Russia's guarantee, to replace the fork-tongued Brits and the weak, wishy-washy Greeks? In order to feel safe?
So if Turkey oversteps the mark in Cyprus, Russia would be duty bound to intervene, if needs be in Turkey?
Or how about China? I'm sure either country would be flattered to be asked to play such a peace-keeping role in the eastern-Med?
Or better still, what about Turkey and all five permanent members of the UN Security Council being guarantors? And if Turkey dared to intervene unilaterally against the wishes of the UNSC, all would be duty bound to kick Turkey's backside?
How does any of this sound? Does this solve the guarantee issue? Would everyone feel safe with such an arrangement?
