A nation is not a state, and while traditionally monocultural, it may also be multicultural in its self-definition. The term nation is often used as a synonym for ethnic group (sometimes "ethnos"), but although ethnicity is now one of the most important aspects of cultural or social identity, people with the same ethnic origin may live in different nation-states and be treated as members of separate nations for that reason. National identity is often disputed, down to the level of the individual.

When the Ottomans captured Cyprus they knew very well that Cypriots are Greeks. After the Ottoman rule ended its remnants did not have a separate self-determination right under any excuse, let alone with the excuse that "most Cypriots are Greeks and we are not", as if they didn't know this when they captured Cyprus in order to exploit us.
We have made the compromise that Cyprus will be an independent country (actually Makarios is the one who first proposed this), although we knew full well that the hawks would never allow the tiny Cyprus to be truly and fully independent. The 1960 agreements that were forced on us by the foreigners were a proof for this.
We are committed to independence, but we want it to be a true one, that will not make Cyprus a Turkish or British protectorate, and where all Cypriots will be equal without divisions and racist discriminations.
