This week on Notes from the World, we speak with Michela Wrong, a British journalist and author who has spent three decades covering Africa and who is the author of, among other books, In the Footsteps of Mr. Kurtz: Living on the Brink of Disaster in the Congo, I Didn't Do It for You: How the World Betrayed a Small African Nation (about Eritrea) and Do Not Disturb: The Story of a Political Murder and an African Regime Gone Bad, which focuses on the murder of Rwanda’s former head of intelligence Patrick Karegeya in Johannesburg, South Africa in 2013. We spoke about the history of DR Congo, the rise of Paul Kagame and the Rwandan Patriotic Front and the pitiless, expansionist authoritarian state that Rwanda has become under his rule.
