Shimon Peres
The former Israeli president and prime minister once praised Nelson Mandela as a model for global leadership. Indeed, Peres himself earned comparisons to Mandela by none other than Barack Obama.
But Peres had not always loved Mandela.
In the 1970s, while he was Israel’s defence minister, Peres oversaw the sale of arms to South Africa’s apartheid government, some of which were unleashed on black South Africans.
