According to the BBC, Bin Laden's call for Holy War to Sudan and Hamas 'fell on deaf ears'.

The trouble is, do they need any hints from Osama? They seem to have the idea pretty well themselves.

The above link is to a story about violence spreading from Western Sudan. Although Chad itself is a majority Muslim country, that very situation tells me that it must be a moderate one- since there is a sizeable Christian minority and no civil war. And being moderate these days just isn't good enough for the A-list Jihadis. Additionally, it's been clear to me for some time what the Jihadi aim is in North Africa: obviously they want an Islamic caliphate stretching across Africa from Nigeria to Sudan, and extending South from there.
