Can the the Democratic Republic of Congo ever recover from being one of Africa's failed states?

The citizens of DR Congo pray to be delivered from the brutal militias that still control parts of the eastern provinces, where rape has become so commonplace that one senior UN official called the country the rape capital of the world. The prestigious Foreign Policy magazine's Failed States Index puts DR Congo in the critically failed category. Only Somalia, Chad and Sudan (when it included South Sudan) have worse rankings and, like DR Congo, they are all African nations. The recently released UNDP report on human development indicators put the former Belgian colony at the bottom of the 187 countries it surveyed. Many wish for the Belgians to return to solve the country's problems.
