Is South Sudan independence a lost cause after 6 years?

South Sudan severed its ties from Sudan after over two decades of civil war between Arab dominated north, and predominantly African and Christian South in 2009 which costed over 2 million lives.

The independence of South Sudan was a milestone to be celebrated and which gave her citizens hope for better livelihood and economic empowerment, through exploitation of numerous natural resources, notably crude oil, but that seems to be a distant achievement now.
