An unsung weapon against terrorism that has proven successful in Africa is the power of the airwaves — shortwave radio reaching people with reliable information, and programming that helps educate them, connect them and imagine a different kind of future. The ubiquity of cellphones allows people in conflict regions to call in, challenge abuses of power and have a voice. That's worked in the Congo, with Radio Okapi. It's working now in areas where Boko Haram has been active in West Africa, and the new Dandal Kura radio network is now broadcasting. Host Mary Kay Magistad talks with her old editor and friend David Smith, who helped set up both.
