What did you mean some time back when you said "South Africa disn't have the infrastructure to maintain nukes."
Dude... you are taking this thread in all sorts of directions.. LOL
I have heard no news of the South Africans receiving a nuke gift wrapped from any other country.
Isreal. Everything they got.. all their tech... came from Isreal.
When S.Africa lost it's nukes, all the infrastructure... whatever there was, was dismantled and most of it vanished back to Isreal.
Also look up their nuclear test called "vela incident".
en.wikipedia.org
Thier resources were limited and all they could make was a basic gun-type nuke. They made 6 or 7 of those.
But that was OK since they said "we only want something that can be kicked off the back of a plane".
Before they gave up their nukes, they were moving to an implosion-type weapon that would have used the fuel from those 7 nukes and made far more efficient 25-30 nukes (or more) out of it.
They did not... as far as I know... have secret nuclear cities dedicated to nukes research like the Russian Arzamas-16 or Pakistan's Kahuta.
The uranium enrichment tech they used (they did not have the Plutonium bomb) was called "Nozzle enrichment" which is far less efficient than the centrifuges we used.
Point it, they could not sustain the effort.
