This ideology will also allow the terrorists to place the blame on the victim, who is viewed as being responsible for the violence in the first place.The context in which terrorist tactics are used is often a large-scale, unresolved political conflict. The type of conflict varies widely; historical examples include:

Secession of a territory to form a new sovereign state or become part of a different state
Dominance of territory or resources by various ethnic groups
Imposition of a particular form of government
Economic deprivation of a population
Opposition to a domestic government or occupying army
Religious fanaticism

Responses
Responses to terrorism are broad in scope. They can include re-alignments of the political spectrum and reassessments of fundamental values. Specific types of responses include:

Targeted laws, criminal procedures, deportations, and enhanced police powers
Target hardening, such as locking doors or adding traffic barriers
Preemptive or reactive military action
Increased intelligence and surveillance activities
Preemptive humanitarian activities
More permissive interrogation and detention policiesThe term "counter-terrorism" has a narrower connotation, implying that it is directed at terrorist actors. Terrorism research
Terrorism research, also called terrorism studies, or terrorism and counter-terrorism research, is an interdisciplinary academic field which seeks to understand the causes of terrorism, how to prevent it as well as its impact in the broadest sense. Terrorism research can be carried out in both military and civilian contexts, for example by research centres such as the British Centre for the Study of Terrorism and Political Violence, the Norwegian Centre for Violence and Traumatic Stress Studies, and the International Centre for Counter-Terrorism (ICCT).
The group developed ideas—such as targeted killing of the leaders of oppression—that were to become the hallmark of subsequent violence by small non-state groups, and they were convinced that the developing technologies of the age—such as the invention of dynamite, which they were the first anarchist group to make widespread use of—enabled them to strike directly and with discrimination.David Rapoport refers to four major waves of global terrorism: "the Anarchist, the Anti-Colonial, the New Left, and the Religious. The first three have been completed and lasted around 40 years; the fourth is now in its third decade." Infographics
Types
Depending on the country, the political system, and the time in history, the types of terrorism are varying. In early 1975, the Law Enforcement Assistant Administration in the United States formed the National Advisory Committee on Criminal Justice Standards and Goals. One of the five volumes that the committee wrote was titled Disorders and Terrorism, produced by the Task Force on Disorders and Terrorism under the direction of H. H. A. Cooper, Director of the Task Force staff. The Task Force defines terrorism as "a tactic or technique by means of which a violent act or the threat thereof is used for the prime purpose of creating overwhelming fear for coercive purposes". It classified disorders and terrorism into six categories:
Civil disorder – A form of collective violence interfering with the peace, security, and normal functioning of the community.
