IIRC the author is opinionated and critical of AFRICOM, but that caveat aside his article does pose questions. Notably:
since AFRICOM began, key indicators of security and stability in Africa have plummeted according to the Defense Department’s Africa Center for Strategic Studies, a Pentagon research institution. “Overall, militant Islamist group activity in Africa has doubled since 2012,” according to a recent analysis by the Africa Center.

If AFRICOM's role is to help nation-states combat jihadist insurgencies then neither "roll-back" or containment appears to be working. The author contends, in part supported by the DoD analysis, it is making things worse.
