Why isn't anyone calling it as it is. S.sudan as a country is not viable. The people have absolutely no sense of values or the minimum acceptable human behaviour to hold their nation together. Wazungus might be saying the mind of an African is not fully developed but for our dinka and nuer brothers, am afraid the brain is yet to form leave alone develop.

Anyone who has been to south Sudan knows God was extremely generous to their land but balanced it out by denying them brains. They cannot grasp the concept of law and order. Kenyan corporates operating there have a budget for bribing these mad men.
A civil matter is settled by guns and throwing you behind bars. If you demand money from a dinka who owes you, he sends an army batallion to silence you. Our company has spent crazy amounts of money to secure the release of our senior managers arrested on wild allegations.
One of the Kenyan banks helped them pay the soldiers when their oil cash dried. They are yet to pay back and they don't believe they owe the bank any money. Its in their own country after all.

A friend tried commercial farming by leasing land. When the venture started looking promising, the owner of the land called in the police to chase away the guy.
The list is endless.
One can only wish Kenya was a military powerhouse . The only solution for south Sudan is for a stronger country to invade it a la Iraq and Kuwait and run it like a colony for 100 years.

If Riek Machar gets in the way of oilmen making their billions then I think what will happen next is predictable:
There will be a tumultous few months as civil war rages, spies recruited and intelligence gathered. Then poor Riek will get a missile dropped on his head by a drone or taken out by hired mercenaries.
Savimbi is precedent. He was as wily as the devil but they still got him.
The green buck (or the yuan) really is the final word.
