Are America’s closest allies getting cold feet about a friendship that’s lasted since World War II? Christiane speaks to Michael Ignatieff, former leader of Canada’s Liberal Party, about growing unease with Washington. Then, a true story of heroism and disaster on the edge of space. Forty years after the U.S. space shuttle Challenger exploded, shocking America and the world, best-selling author Adam Higginbotham speaks about his minute-by-minute account of the tragedy and the decisions that led to catastrophe. Plus, hopes of progress in Gaza, but in the occupied West Bank, Israeli settler violence continues to devastate Palestinian villages. Jeremy Diamond reports. Also ahead, Christiane’s conversation with a Holocaust survivor and legal titan. At 95 years old, Judge Theodor Meron reflects on a lifetime devoted to pursuing justice and accountability. And as the world marks Holocaust Remembrance Day this week, from Christiane’s archive: how the Nazis’ slaughter of six million Jews shocked the international community into outlawing genocide.
