This chapter aims to suggest that the turnaround in Western antiterrorism policies took place in the 1990s and early 2000s. In the 1990s, terrorism underwent important changes in the 1990s and became recognised as a global threat. The number of casualties in terrorist attacks rose together with a change in motivations and nature of the attacks. Even if dedication to the fight against terrorism started to grow in the 1980s, the 1990s can be viewed as a global turning point in the way in which terrorism was viewed and treated globally. Terrorism became an open concern of the organisation and the limitations provided by its constitution were steadily overruled by a new policy which put the fight against terrorism in a central position for the organisation during the 1990s. Political crimes, and terrorism in particular, have throughout history received different treatment in comparison to ‘common’ crimes.
