A quick review:
The South Sudanese fight Bashir for ages and finally, with the help of international pressure, get their own country. One thinks that they are tired of fighting and will focus on building their own country. Instead Kiir fires Machar, with results as predictable as that the sun will rise tomorrow. Tens of thousands are killed; hundreds of thousands are injured; millions are displaced or affected in other ways. Kiir rehires Machar.
There are surely better ways to settle employment disputes or to run a country, with plenty of useful lessons available from many other African countries.
