Planning for the next Takur Ghar

The USA is currently facing an increasingly diverse range of threats, including non-state actors, particularly violent extremist organizations attempting to do harm. The national leadership has made it clear that for the near future it will employ Special Operations Forces (SOF) as the tool of choice in short-duration, high-intensity operations that have more in common with the battle of Takur Ghar, than those with a larger footprint. It is critical then that the lessons of the past are learnt now and are applied before employing SOF in the future. This becomes especially important given the short lead-time in concert with the short-duration/high-intensity tempo of their operations. In the Battle of Takur Ghar, during Operation Anaconda, rigid adherence to the joint functions, especially clearer and more robust Command and Control (C2) and Intelligence, Surveillance, and Reconnaissance (ISR) in the planning and execution of Operation Anaconda would have yielded a better operational outcome and saved lives. With the benefit of hindsight, many things could have been done differently, but several key issues stand out. The C2 structure must include all components from the outset to synchronize effects and rapidly re-task ISR. There must be multiple communications redundancies and adequate bandwidth. Finally, all SOF, conventional and interagency capabilities must be synchronized under one task force commander with a sufficiently robust C2 infrastructure to direct the entire effort. As our nation calls on SOF at an ever-increasing rate, we must take those lessons learned and apply them to future operations.

Business and peace in the Niger Delta: what we know and what we need to know

The global restructuring of state–society relationships driven by neoliberal logic has not only allowed for the taming of the ‘state’, which has paradoxically accentuated its inadequacies, but has also facilitated, for better or for worse, the emergence of business – especially transnational corporations – as a major political force in global governance. Consequently, while the issues of peace and conflict have traditionally been the concern of governments, businesses are now increasingly being expected to make peace and conflict their concern. However, despite claims and counterclaims that businesses can be moneymakers and peacemakers, analyses of the relationship between business and peace remain largely embryonic. This paper seeks to contribute to this emerging business and peace debate by drawing on insights from the Niger Delta conflict to ascertain what we know and what we need to know if businesses are to become peacemakers in conflict zones in Africa.
