The partition of the Island of Cyprus into ethnically distinct semi-states has been universally deplored. It's self evidently a Bad Thing, and this explains the endless efforts to undo it. But I'd argue that the current two-state arrangement is far better than the "unified" country it replaced because the Greek and Turkish communities had never really lived together in peace and harmony. Relatively peaceful co-existence was maintained only by force (or the threat of force) first by the Ottomans, then by the British.
The Constitution implemented after independence attempted to paper over the fissures arising from two very distinct and mutually-hostile communities having to live together under a single polity. Predictably the resulting compromise was arcane, complex and highly unstable. Clauses geared towards countering crude majoritarian rule (4:1 Greek/Turkish ratio) ended up creating legislative gridlock from the highest levels down to the street level. According to one Constitutional scholar 'the Constitution of Cyprus stands alone among the constitutions of the world".
Not surprisingly the two communities were at one another's throats from the outset. Issues of contention included schooling, media control, taxation and the ability to create ethnically and religiously based municipalities. Such disputes were resolved by violence on the ground rather than by political means. The 'land of the sirens' came to represent something very different to that portrayed in Greek mythology.
Eventually the attempt to reunite with Greece in 1974 precipitated a Turkish invasion and the de facto two-country solution we have today, with Turks in the North, Greeks in the South. Obviously the creation of this entity was accompanied by mass ethnic cleansing in both directions and involved much suffering and dispossession. But in due course Cyprus (i.e. the Greek part) became free, peaceful, prosperous and democratic. The inter-communal violence that scarred the island for centuries is no more. There are no more ethnic enclaves. Ordinary Cypriots are free to go wherever they want in peace.
The Turkish-ruled North has been nowhere as successful, suffering as it does from Islamic obscurantism, a large (and deeply-resented) influx of peasants from the Anatolian plains and a generally limited entrepreneurial culture. To add to their woes they've been enriched by large numbers of fast-breeding Africans. This large-scale immigration might in time lead to the kind of communal strife commonplace when the island was 'united'. But for now both sides of the Green Line are mercifully free of this scourge.
All of this lends credence to the old adage 'high fences make good neighbours'. They really do. The experience also underlines the insuperable challenges that can arise when incompatible peoples occupy the same physical space. The corollary being that those now working to beset White peoples with such an abomination are traitors and should be treated as such.
