Topics as diverse as the evolving spectrum of conflict, innovations in weaponry, automated and autonomous attack, the depersonalisation of warfare, detention operations, the influence of modern media and the application of human rights law to the conduct of hostilities are examined in this book to see to what extent existing legal norms are challenged. The book takes each topic in turn, explains relevant provisions of contemporary law and analyses exactly where the legal problem lies. The analysis then develops the theme, examining for example the implications of current rules as to deception operations for certain applications of cyber warfare. The text is written in an accessible style, and demonstrates the continuing relevance of established rules and the importance of compliance with them. Useful for academics, military, governments, ministries of defence, ministries of foreign affairs, libraries, diplomats, think tanks, policy units, NGOs, and all others with an interest in law of armed conflict issues such as journalists and students.
