ABSTRACT
This chapter investigates why certain governments or organisations (such as the US and the EU) respond to some cyberthreats - such as cyberterrorism - differently than to others. It focuses on counter-measures after 9/11 since it can be considered a turning point that changed aspects of the cyberthreats debate. However, recent developments to counter cyberterrorism seem to confirm fundamentally divergent patterns and pathways. Notwithstanding these differences of temperament, substantial progress on transatlantic collaboration to counter cyberterrorism has been achieved and this chapter reviews recent progress to date. David Dolowitz and David Marsh argue that this dynamic can also be observed in cyberspace, since technology can also push governments into policy 'transfer because of the speed with which it forces change. The openness of the Internet has encouraged cybercriminals to spread information and organise transnational crimes, threatening informational as well as national security. One can be linked to the differences of strategic culture that create an atmosphere of little trust.
