lets close the gates of cyprus to world and u live there happly ever after
We don't want to close the gates of Cyprus to the world because we would have huge negative consequences from doing so.
Therefore taking the risk for keeping open the "gates to the world" is worth it.
Now tell me why it is worth it for us to keep the gates open to the occupied Cyprus and increase the risk for disaster? So some people will go play in the Casinos and go tourism in the occupied areas?
