The participants to the workshop were divided into three working groups, to develop potential scenarios that would help identifying some possible developments concerning the future of terrorism and counterterrorism in the NATO zone at the horizon 2035. Using previous days' inputs and the trajectories approach, the bifurcations method has been applied to illustrate alternative scenarios. The three groups were: Ethics; Science & Technology; and Counter-Terror Strategies. Working with given hypothesis and five variables identified during a former exercise, the groups designed potential futures based on three centers of gravity in the system: 1. The defence of democracy, the UN values and ethics; 2. Terrorists' goals, preparedness, and strategies; and 3. Technology as an anticipative tool to terrorism.
