Ohh, okay. AIDS first emerged in Africa in the early 1980s. It was first reported in the USA in 1984. The USSR did not acknowledge its presence, because it was regarded as a “decadent western disease” or something similar (much the same as North Korea’s denial of covid19). So we can’t really give a definitive answer to whether or not Lenin (who died in 1924) had some kind of pre-curser AIDS or HIV infection before its discovery in Africa, but the odds would be astronomically against this.
What we do know, however, is that people with psychotic or schizophrenic tripe mental health diagnoses commonly confuse events on a timeline, and operate with a delusional belief system about both cause and effect and chronological order.
Is your thinking always that disordered?
