This book develops the idea that since decolonisation, regional patterns of security have become more prominent in international politics. The authors combine an operational theory of regional security with an empirical application across the whole of the international system. Individual chapters cover Africa, the Balkans, CIS Europe, East Asia, EU Europe, the Middle East, North America, South America, and South Asia. The main focus is on the post-Cold War period, but the history of each regional security complex is traced back to its beginnings. By relating the regional dynamics of security to current debates about the global power structure, the authors unfold a distinctive interpretation of post-Cold War international security, avoiding both the extreme oversimplifications of the unipolar view, and the extreme deterritorialisations of many globalist visions of a new world disorder. Their framework brings out the radical diversity of security dynamics in different parts of the world.

Shows how regional and international interventions, combined with piracy, have compounded pre-existing tensions in the Horn of Africa.

At the height of the Cold War, Soviet ideologues, policymakers, diplomats, and military officers perceived the countries of Africa, Asia, and Latin America as the future reserve of socialism, holding the key to victory over Western forces. The zero-sum nature of East-West global competition induced the United States to try to thwart Soviet ambitions. The result was predictable: the two superpowers engaged in proxy struggles against each other in faraway, little-understood lands, often ending up entangled in protracted and highly destructive local fights that did little to serve their own agendas. Using a wealth of recently declassified sources, this book tells the complex story of Soviet involvement in the Horn of Africa, a narrowly defined geographic entity torn by the rivalry of two large countries (Ethiopia and Somalia), from the beginning of the Cold War until the demise of the Soviet Union. At different points in the twentieth century, this region—arguably one of the poorest in the world—attracted broad international interest and large quantities of advanced weaponry, making it a Cold War flashpoint. The external actors ultimately failed to achieve what they wanted from the local conflicts—a lesson relevant for U.S. policymakers today as they ponder whether to use force abroad in the wake of the unhappy experiences in Iraq and Afghanistan.

As the so-called Arab Spring has slid into political uncertainty, lingering insecurity and civil conflict, European and American initial enthusiasm for anti-authoritarian protests has given way to growing concerns that revolutionary turmoil in North Africa may in fact have exposed the West to new risks. Critical in cementing this conviction has been the realisation that developments originated from Arab Mediterranean countries and spread to the Sahel have now such a potential to affect Western security and interests as to warrant even military intervention, as France’s operation in Mali attests. EU and US involvement in fighting piracy off the Horn of Africa had already laid bare the nexus between their security interests and protracted crises in sub-Saharan Africa. But the new centrality acquired by the Sahel after the Arab uprisings – particularly after Libya’s civil war – has elevated this nexus to a new, larger dimension. The centre of gravity of Europe’s security may be swinging to Africa, encompassing a wide portion of the continental landmass extending south of Mediterranean coastal states. The recrudescence of the terrorist threat from Mali to Algeria might pave the way to an American pivot to Africa, thus requiring fresh thinking on how the European Union and the United States can better collaborate with each other and with relevant regional actors.

The humanitarian crises caused by civil conflicts and wars in Africa are too great in scope for an adequate and effective continental response. The founding of the African Union and the drafting of the Responsibility to Protect doctrine, the basis for collective action against genocide, ethnic cleansing and crimes against humanity makes this a critical time to reflect on how best to address regional conflicts. This book responds to new regional conflicts over health, water, land and food security in the world's poorest, most socially fragmented continent. The work assesses African regional security arrangements and provides new policy recommendations for the future.

This book brings to fruition the research done during the CEA-ISCTE project ‘’Monitoring Conflicts in the Horn of Africa’’, reference PTDC/AFR/100460/2008. The Portuguese Foundation for Science and Technology (FCT) provided funding for this project. The chapters are based on first-hand data collected through fieldwork in the region’s countries between 4 January 2010 and 3 June 2013. The project’s team members and consultants debated their final research findings in a one-day Conference at ISCTE-IUL on 29 April 2013. The following authors contributed to the project’s final publication: Alexandra M. Dias, Alexandre de Sousa Carvalho, Aleksi Ylönen, Ana Elisa Cascão, Elsa González Aimé, Manuel João Ramos, Patrick Ferras, Pedro Barge Cunha and Ricardo Real P. Sousa.
