For as long as there has been technology (the application of science and innovation) and for as long as there has been strategy (the use of forces and resources to achieve political goals) there has been a relationship of sorts between these two preoccupations. This article inquires into the nature of the technological–strategic relationship which governments, such as that in the UK, draw upon as they confront international terrorism. To what extent has the historical technostrategic dynamic remained relevant and useful, and where has new thinking been required? The article suggests that a new and more complex understanding of the technology–strategy relationship is emerging in the context of counterterrorism. The challenge facing government is to maintain a technological edge against its terrorist adversary, without exaggerating the adversary's capability, and while ensuring that its counterterrorism strategy pursues a coherent and persuasive political goal.
