In this book Barry de Vries addresses the issue of autonomous weapons in international criminal law. The development of autonomous weapon systems is progressing. While the technology advances, attempts to regulate these weapons are not keeping pace. It is therefore likely that these weapons will be developed before a new legal framework is established. Many legal questions still remain and one of the most important ones among them is how individual responsibility will be approached. Barry de Vries therefore considers this issue from a doctrinal international criminal law perspective to determine how the current international criminal law framework will address this topic.
