Time is almost up on a 2005 comprehensive peace agreement in Sudan that slated this to be the year for a referendum on South Sudan's independence. International Crisis Group Africa Analyst Zach Vertin says that though one of the aims of the original agreement was to make unity between the North and South attractive, that effort has failed and South Sudanese will most likely vote in favor of secession from Khartoum. Key issues such as demarcation of the North/South border, wealth sharing and a timely referendum will be the focus of this democratic process unfolding in Sudan, Vertin says.
