The United States' use of drone warfare is encouraging a new arms race that will lay the foundations for an international system that is increasingly violent, writes Michael Boyle in the new issue. The author, who served on President Obama's counterterrorism group in the run-up to the 2008 election, argues that the US administration's growing reliance on drone technology is having adverse strategic effects that have not been properly weighed against the tactical gains associated with killing terrorists.

Elsewhere, Alex Vines, Research Director and Head of the Africa Programme, examines how the African Union has handled peace and security challenges since 2002 and defines what has been successful and what remains aspirational. Also, Chris Alden and Maxi Schoeman write on South Africa's increasingly assertive role on the continent, but argue that it remains constrained by three factors: the unresolved issue of identity, a host of domestic constraints linked to internal politics and the divisive continental reaction to South African leadership.

Finally, Sten Rynning from the University of Southern Denmark examines the new strategic reality of armed intervention, drawing on two in-depth assessments of NATO's experiences in Afghanistan and Libya.
