South Africa at the time was (and still is: as much as our government would have the rest of the world believe otherwise) a third world country
While I spent some time reading geopolitics, it was often around the political economy of oil, as well as other resources. I don't think first world/third world terminology is in use any more. Somebody somewhere decided it was not polite or something. That said, I know very little about South Africa, other than the context it was in the cultural consciousness way back in the 80s, but it wouldn't have occured to me to think of it as third world. But I see on Wiki, labels like "newly industrialized", "middle power" and "developing country". I love how these terms come with built in normative ideology, as though these were inherant stages like childhood-adolescence-adulthood. So much for improving on "third world". Ol' Wiki also says you have three capital cities, ten official names and eleven official languages. South Africa sounds like an even messier aggrieved soup of multicultural appeasement than Canada, LOL
I think, trying to label and stick a nation in a box can be misleadingly reductive. Canada is aa bit of a moving target to nail down, and looks very different depending on what angle your peering at it from. We get to enjoy a likeable persona built from a warm fuzzy mythology about how awesome Canadians are, how peaceful, how courteous and how green we are. The reality is a bit murkier. We have an angry polarized population with the left despising the right, an eternal clusterfuck with our indigenous population, fuelled now by a privileged young white educated class who are always chirping about decolonizing and unceded lands, virtuously crowing about our oppressive villainy. Or then there's the whole peaceloving even though we trundle alongside the US to all its wars and make a serious bundle on arms manufacture. My favourite facepalm is how we manage to sell ourselves as green. Our very large parcel of land is some of the richest on earth for oil, bitumen, gas, and coal. We strike down regulations and protections whenever they inconvenience any resource industry. We dangerously overfish our fisheries while toxifying them at the same time.Our timber industry clearcuts as fast and frenzied as it can. We've irrepairably decimated and poisoned the country to stay drunk on endless mining wealth--zinc, copper, gold, nickel, diamonds, asbestos, molybdenum, potash, uranium, rare isotopes. We are a global power in mining and resources with all the nasty ugliness that comes with it We have leveraged technological know how to gain power in mining all over the world, and our foreign policy uses whatever it can to leverage other countries either for their resources, or to be a market for ours. We market toxic substances that are illegal here or controlled because of environmental risks, to other nations and pressure them not to make any regulations. Not really so warm and fuzzy.
We occupy such a weird space. We have good guy rep as global diplomats. But we are arms dealers and military adventurers and meddlers. We are nasty mining overlords who play sneaky geopolitical games. Hardly the gleaming global citizen depicted in our PR. But, simultaneously, we are often at the mercy of our larger markets in ways that make us somewhat akin to a banana republic, where we sell raw materials cheap and then buy back expensive manufactured goods. We have dependent relationships that erode our sovereignty. So we are sort of imperial small-c colonizers, first world shot callers, new age global citizens, two faced extorters and exploiters, bullied third world resource outsourcing for more powerful allies.
I think, the identity, makeup and inter-relational nature of a state isn't all that simple to really sum up with vaguely defined blanket terms like first or third world. South Africa sounds like an interesting and confusing place to try and unpack.
