Richard Nixon
Nixon is best known for the Watergate scandal and also for losing to one Kennedy (John) and nearly losing to another Kennedy (Robert) in the presidential elections.
What is not well known is the fact that Nixon was like a lot of conservative American politicians, in that the African National Congress was a political football that could be played in their fight against the Soviets during the Cold War. In their efforts to defeat the Russians, who threw support behind the ANC, there was little interest in helping to defeat the white minority regime in South Africa.
