It is now well established that both the "war on terror" and its descendents have been heavily constituted through highly urban discourses, materialities and practices. This lecture, which draws on a major book with the same title published recently by Verso, seeks to demonstrate that new ideologies of permanent and boundless war are radically intensifying the militarization of urban life in the contemporary period. The lectures delineates the ways in which contemporary processes of militarisation -- which surround what I label the "new military urbanism" -- raise fundamental questions for critical urban scholarship because of the ways in which they work to normalise the permanent targeting of everyday urban sites, circulations, and populations. Focusing primarily on US military security and military doctrine, culture and technology, this lecture explores the new military urbanism’s five inter-related foundations in detail. These are: the urbanisation of military and security doctrine; the links between militarised control technologies and digitised urban life; the cultural performances of militarised media consumption; the emerging urban political economies of the ‘security’ industries; and the new state spaces of violence. Following the elaboration of each of these themes, the lecture concludes by identifying ways forward for critical urban research in exposing and confronting the normalization of the new military urbanism.
