Blood samples to be tested for malaria are seen at the Aweil State Hospital in Aweil, the only hospital in the South Sudanese state of Northern Bahr el Ghazal, June 2, 2012. As in many developing nations, international aid is both an invaluable help to South Sudan and a crutch that sometimes enables it to avoid reality. Development experts have grown more sophisticated in recent decades about how they deliver aid.
