Just watched
Mabior Garang's interview on CCTV News (love their 8-9p.m daily African news bulletin). Apparently he now is a spokesman for the rebels. Says one of their demands in the peace talks with the gov't side is for a federal system of gov't (as well as withdrawal of Ugandan troops), something which the Salva Kiir side is not keen on, instead preferring a unitary state which the rebels claim is a failure.
Life is like playing a violin solo in public and learning the instrument as one goes on.
