I saw a pretty nasty video about this in the past.
If they couldn't defend themselves before, I'm not sure
what an imaginary line is going to do.
I got a strong feeling that this isn't going to change much
for a while until they can strongly enforce their
boundaries and protect people once they figure out how
to divide their oil.
Although I guess they need to start somewhere.
Doesn't look especially good, but best wishes to them.
From the article:
"More than a half-dozen renegade groups are battling the government, some with thousands of fighters. And relations with the north are still dicey. Negotiators have yet to agree on a formula to split the revenue from the south’s oilfields, which have kept the economies of both southern and northern Sudan afloat. And Mr. Bashir’s army has been pounding southern-allied rebels who have refusing to disarm just north of the border in the Nuba Mountains, which some analysts worry could drag the whole region back into a full-scale war."
