The end of the Cold War ushered in a new phase of global security in which new threats and challenges emanate from non-conventional sources, and in which the weapons and means to prosecute war harness new technology. By the mid-1990's terms such as cyberwar and netwar were being used to explain a new way of thinking about war. The intervening years have seen the development of new defence policies, such as the US 2020 Vision and the Revolution in Military Affairs, whilst the threat of terrorism has become a painful and sad reality. The period has also seen the development and deployment of a range of new technologies for military operations ranging from new smart mechanisms to deliver weapons, to surveillance and communications technologies that can change the very nature of warfare and security. This book attempts to consider this balance between the technologies and policies deployed to respond to terror and the need for human and civil rights.
