when will this end?

sanctions and Congress had to override the veto. Reagan's Director of Communications was Pat Buchanan, an openly racist person who spoke of supremacist societies as a good thing.
"The regime of apartheid in South Africa, under which nonwhites were systematically oppressed and deprived of their rights, is remembered as one of the worst crimes against humanity of the 20th century.

Despite a growing international movement to topple apartheid in the 1980s, President Ronald Reagan maintained a close alliance with a South African government that was showing no signs of serious reform. And the Reagan administration demonized opponents of apartheid, most notably the African National Congress, as dangerous and pro-communist. Reagan even vetoed a bill to impose sanctions on South Africa, only to be overruled by Congress.

On a trip to the United States after winning the Nobel Prize in 1984, Bishop Desmond Tutu memorably declared that Reagan’s policy was ”immoral, evil and totally un-Christian.” Reagan’s record on South Africa was also marked by at least one embarrassing gaffe, when he told a radio interviewer in 1985: “They have eliminated the segregation that we once had in our own country — the type of thing where hotels and restaurants and places of entertainment and so forth were segregated — that has all been eliminated.” Of course, that was simply not true, and Reagan later walked the statement back.
