I don't see a single word on why Nigeria would be particularly "doomed".
I can't recall seeing much news/propaganda about Sudan becoming prey for Al Quaeda either. Do we read the same things? If you'd written Somalia, then perhaps I could agree.
Does Sudan sponsor terrorism? Despite increasing cooperation by Sudan, the U.S. State Department continues to formally designate it as a "state sponsor of terrorism." The State Department first labeled Sudan a sponsor of terrorism on August 12, 1993. Since then, the United States has accused Sudan of harbouring members of al-Qaeda, Hezbollah, Hamas, Palestinian Islamic Jihad, the Abu Nidal Organization, Jamaat al-Islamiyya, and Egyptian Islamic Jihad, each classified as a terrorist organization.
