Negotiation encourages more terrorism  There are two ways in which negotiation encourages more terrorism. First it shows that violence can achieve its aims, a group that has committed violent acts and received negotiations in return will believe that they will gain even more from greater levels of violence. Secondly as argued in the previous point negotiations with terrorist groups gives legitimacy to political violence. This in turn will encourage other groups to resort to violence to achieve their political goals as they have seen it work for another group. Thus for example when the Fatah movement and the Palestine Liberation Organisation were legitimised by a peace process and the recognition of a form of Palestinian government other groups such as Islamic Jihad and Hamas came to believe that they could take terrorist actions further in order to liberate Palestine through an armed struggle.
