"Clapham and Gaeta are to be congratulated for their Herculean efforts in assembling a book that fairly represents the vast disagreement and contestation that currently inhabits the legal regulation of warfare. The Handbook paints a complex picture of overlapping legal domains all pushing and competing to regulate military conduct. Whether or not this competitive process is coherent depends on which author in the Handbook is asked, a pluralism that accurately reflects the state of the field today." -AJIL, Jens David Ohlin, Cornell Law School
