Been to South Africa on business. (Long time ago). Interesting country.
When Q used the abbrev SA, at first we all thought for sure it meant Saudi Arabia (and maybe it did, then).
Then I wondered if it could also mean South America.
Now the possibility of South Africa arises.
BTW, the people in South Africa abbreviate their country ZA using the Africaans word for south.
I have no idea. It's not my OC, it's from memearchives.
One more thing about South Africa.
My English friend there, long time ZA resident but originally from England, passed along a rumor that was quite widely believed among some of the well educated South Africans, that their country did possess a covert atomic bomb capability.
I have no idea whatsoever if this rumor has any factual basis. The timeframe when I heard the rumor was around the mid 1990s.
