This Handbook on Democracy and Security provides a fascinating analysis of the predominant causes of democratic erosion facing the world today. The book's contributors define and bound new threats such as the double-edged sword of militant democracy as well as reexamine long-standing threats such as the triumphs and pitfalls of democracy assistance. Part IV of the book, in particular, offers keen insights regarding how online media both bolster and undermine democracy. This Handbook should be required reading for any democratization student, scholar or practitioner. -- Brigitte Seim, University of North Carolina, Chapel Hill, US In light of the current third wave of autocratization worldwide, understanding the factors that sustain democracy is more critical than ever. This volume makes a valuable contribution to that understanding by exploring this at a micro level, focusing on the human factors and security of individual citizens that undergird democratic institutions. It is an extremely timely and very important work. -- Staffan I. Lindberg, University of Gothenburg, Sweden
