“No more mine-laying. No more murder. No more abduction of women and children. No more attacks on headmen. No more raids across the border. So long as these conditions do not exist there will be no withdrawal [from South-West Africa] of South African troops.”

1990s, Victory speech (1994)
Context: My fellow South Africans — the people of South Africa:
This is indeed a joyous night. Although not yet final, we have received the provisional results of the election, and are delighted by the overwhelming support for the African National Congress.
To all those in the African National Congress and the democratic movement who worked so hard these last few days and through these many decades, I thank you and honour you. To the people of South Africa and the world who are watching: this a joyous night for the human spirit. This is your victory too. You helped end apartheid, you stood with us through the transition.

Context: As any television viewer or newspaper reader could discern the end in South Vietnam, in April 1975, came with incredible suddenness, amid scenes of unmitigated misery and shame. Utter defeat, panic, and rout have produced similar demoralizing tableaux through the centuries; yet to those of us who had worked so hard and long to try to keep it from ending that way, who had been so markedly conscious of the deaths and wounds of thousands of Americans and the soldiers of other countries, who had so long stood in awe of the stamina of the South Vietnamese soldier and civilian under the mantle of hardship, it was depressingly sad that so much misery should be a part of it. So immense had been the sacrifices made through so many long years that the South Vietnamese deserved an end- if it had to come to that- with more dignity to it.
