How far was the end of apartheid a result of the fall of the USSR?

by idvckalt

A completely insane comment in /r/worldnews is filled to the brim with lies but makes one interesting claim - that the end of apartheid was due to the fall of the USSR.

I'm now wondering how true this is. The ANC/Mandela's communist links are pretty well known but I'd never considered this a possibility.
