(Politico) – When President Barack Obama leaves the White House next January, people around the world will debate his legacy for years to come. But for the children of South Sudan, his legacy is clear: He has failed them. Last week, the White House announced which countries will receive waivers to the prohibition on U.S. security assistance under the Child Soldiers Prevention Act (CSPA). And this year, as with every other year, South Sudan was included in that list. With this announcement, the Obama administration has squandered its last chance to hold the corrupt, malignant South Sudanese leadership accountable for its crimes, depriving the boys and girls who have suffered at its hands of any justice.
