In this month's edition of Witness, Tanya Beckett introduces us to another five important moments in history. We will hear from Judge Sisi Khampepe who shares her memories of serving on the Truth and Reconciliation Commission in South Africa, a British diplomat tells us about the time France vetoed Britain's entry into the European Economic Community and a former member of the Viet Cong remembers the Tet Offensive, a turning point in the Vietnam War.
