must submit a written declaration that they do not recognise the breakaway administration, hold an office there or hold any property belonging to a Greek Cypriot.
Somebody could still lie, but those who are found to be lying will have the citizenship removed.
I am not sure if this is the best way to deal with the issue, however something needs to be done, and probably it will be done when the negotiations will permanently fail. It can't be that the Turks drill in our EEZ, the TCs are opening Varosha, and we do nothing to retaliate.
The last few years have proven what I was saying all along. That "confident building measures" are at best useless for our side, because the Cyprus problem has very little to do with confidence and everything to do with interests. It is time for our government to recognize this and adjust its policies accordingly.
