In the current world, terrorism is one of the greatest threats. In turn, many resources have been assigned for the defense of innocent people, who have suffered from the wrath of terrorists. Terrorism is an act of violence that is mostly intentional, which is aimed at furthering some ideologies by the group of people involved. Some of the goals that terrorists seek to achieve are promoting their political, ideological, and religious objectives. Terrorists are out to achieve some certain goals in their activities. Understanding their goals is the best way to learn the motivation behind terrorists, carrying out their terrorism activities. To a terrorist, success is achieved when they achieve the goals, and the cost they incur is not important compared to the success they achieve from their goals. In bid to determine the cost benefit analysis of carrying out the act of terrorism, a terrorist will first determine the protection measures that he has to get through to get to the target, and how much it is going to cost. It is after this analysis that the terrorist decides on the best way to strike. As earlier noted, many resources to fight against terrorism have been assigned.

The reason for keeping the number at a minimum is to avoid any incidents of backlash that may ruin the reputation of the organization and try to show the legitimacy of the grievances they try to air out. Among the reasons, why these people tend to keep their attack at a minimum number is ensuring that the support of the organization is getting economically maintained as well as political support externally. Terrorist groups need to make sure that they maintain the balance of various considerations because of existence of political ideologies to make sure that there is no rise of splinter groups that result from the organization’s activities. Political theory of terrorism has several types and has notable groups in them. Among them is the political theory of Anarchism (Bell, 1982). Although this is not quite a a political expression inherited from terrorism order, Anarchism means rejection of coercive governance, which his in fact an opposition to the regime – what terrorists do – but a very latent and antiwar one.
