Maybe not the USA's AFRICOM, but the alternative African Union forces in an IISS Strategic Comment: http://www.iiss.org/publications/str...ll-on-standby/

Ends with a direct comment:
Meanwhile, AU peacekeeping operations will continue to be conducted by those countries that are willing and capable.
For Africa 'hands' this will come as no surprise, the AU suffers from the problems its predecessor, the OAU, had political declarations are rarely matched by real work and I am slightly puzzled by one nation's failure, Libya which has proclaimed its readiness repeatedly - IIRC with an article in the RUSI Journal.

Not that AFRICOM will "fill the gap".
