More than two million South Sudanese have been forced to flee their homes, many into the perilous swamps, and United Nations officials estimate that at least 50,000 may have died in the last two years. South Sudan hasn’t received the diplomatic or media attention the crisis merits. There was zero coverage of South Sudan’s civil war on American weekday evening network television news shows in 2015, according to the Tyndall Report, a news monitor. We can’t stop every atrocity, and I’m not even sure we can stop this one. But when people are being singled out because of their ethnicity and killed, raped, mutilated and starved, when a government that we helped put in place is regarded by citizens as more dangerous than hungry crocodiles, then surely we can try a little harder.
