Dealing with disputes in Afghanistan: principles and rules for the tactical level

This article addresses the principles that should guide commanders, and the rules they must adhere to, when dealing with community disputes in Afghanistan. An important feature of these principles and rules is that they have been developed to ensure that coalition forces minimize the harm caused to the local population; and that members of the coalition do not violate their own laws and policies. The principles and rules have also been developed to be consistent with counterinsurgency guidance as practiced in Afghanistan. The article concludes with a number of ‘Dos and Don'ts’ concerning dispute settlement that are relevant for coalition forces dealing with disputes at the tactical level. The article also has two appendices, which are intended to guide commanders to better understand dispute settlement systems in Afghanistan.     

Building peace from the margins in Somalia: The case for political settlement with Al-Shabaab

The prevailing discourse in Mogadishu among the federal government of Somalia and the international community is that Al-Shabaab is no longer relevant in contemporary Somali political landscape. In the language of the government, Al-Shabaab is like a lost crocodile thrown out from the river. In the lexicon of the international community, Al-Shabaab is gradually receding. In fact, Al-Shabaab is actually puissant and potent in terms of social, political and military capabilities; not just in Somalia, but also in the wider East Africa region. Why is Al-Shabaab resilient and resistant? Why is it even more effective than the federal government? To answer these questions, this article reveals how Al-Shabaab is increasingly more legitimate than the federal government. In conclusion, the article proposes that negotiated settlement with the insurgency movement could lead to peace in war-torn southern Somalia.
