Ex unitate, vires

South Africa is not a united nation. There are multiculturalist whites, blacks, Coloureds and Indians, who want to live in a diverse country (and assume their children will not revert to the identitarian mean). But there are Afrikaner nationalists, there are black nationalists, there are Zulu nationalists, etc.

For a brief time after 1994, an attempt was made at unity. As we see now, the structure of the country is not that of a united nation. So it must eventually devolve, by breaking up into separate nations or by conquering of other nations by a hegemonic nation, or some combination of the two.

South Africa is diverse. But: Ex unitate, vires. Out of unity, strength. Diversity + Proximity = War.

A first step towards a peaceful solution would be devolving political power to the provinces, to allow nations to voluntarily sort themselves and form a confederation. Switzerland makes this work, with German, French and Italian nations in a confederation. So it is possible - but there is more required than just this for success.
