JUBA, SOUTH SUDAN - JULY 7: Sudanese women wave their national flag as they dance at a cultural festival to celebrate the South Sudan's anniversary July 7, 2012 in Juba, South Sudan. After breaking away from Sudan last year, South Sudan is getting ready for its first independence anniversary celebrations. Over the past year repeated conflict with North Sudan, corruption scandals and economic difficulties have plagued the new country. Further problems caused by the shutdown of its oil production have led to a sharp decline in its currency and a rise in the price of food and fuel. (Photo by Paula Bronstein/Getty Images)
