“There are two things you need to understand about the famine decimating South Sudan, the world’s newest country and one that came into existence largely because of enormous assistance from the US. First, South Sudan isn’t the only country in the region facing mass starvation. A potentially historic famine is also threatening Nigeria, Somalia, and Yemen. Far from Western eyes and far from the headlines, an estimated 20 million people in those four countries are at risk of dying due to a lack of food. Second, these famines weren’t caused by natural disasters like crop failures or droughts. They were man-made.” Vox reports from South Sudan on the the worst famine since World War II.
