Tom's Take: "With its vast oil wealth and immense reserves of human capital, it should be the powerhouse of Africa. Instead, the country faces a sea of troubles, with a president who is absent and an unresolved insurgency. Complicating the situation is Nigeria’s ethnic politics - the divisions between the President, a Northern Muslim refusing to turn over power to his Vice President, a Southern Christian. Among our guests today is one of Nigeria’s literary lions, Nobel laureate Wole Soyinka."
