This course examines the changing character of war and security in a time of rapid and disruptive technological and geopolitical change. The course combines analysis of contemporary policy documents with the interdisciplinary insights of intellectuals that have examined how war has changed in the modern age. Students are introduced to a range of concepts that are currently significant in the policy debates about the future of war – concepts such as ambiguous war, the gray zone, the third offset strategy and the three block war. While the course is grounded in broader debates from social and political though about war and modernity, it explores a range of evolving and inter-related case studies that are central to understanding how war is changing: cybersecurity/artificial intelligence; cities and urban war; drones and the future of robotics; climate change and ecological insecurity. Each year we try to bring a guest lecturer from the Ministry of Defence or the FCO to discuss questions relevant to the course – and to discuss how the course can be relevant to a broad range of careers.
