Book excerpt: Clara Usiskin has spent eight years investigating the 'War on Terror' and its effects in the East and Horn of Africa, documenting hundreds of cases of rendition, secret detention and targeted killings. Her book sets out the historical background to today's covert war, including the early Somali jihads and British repression in colonial Kenya, through to the 1998 US Embassy Bombings in Nairobi and Dar es Salaam, and President Clinton's early rendition programme. America's Covert War in East Africa then looks at the US Military's new Africa Command, with its emphasis on counterterrorism, alongside increasing use of targeted killings by security forces in the region, and continued renditions and secret detention. Finally, Usiskin investigates the shorter and longer term consequences of such intensive militarisation, and the proliferation of surveillance and other technologies of control in East Africa and its surrounding waters, focussing in particular on their impact on vulnerable ethnic and religious groups in a highly volatile region.
