, an American scholar, has noted that it is not only individual agencies within the same governmental apparatus that cannot agree on a single definition of terrorism. Experts and other long-established scholars in the field are equally incapable of reaching a consensus. C. A. J. Coady has written that the question of how to define terrorism is "irresolvable" because "its natural home is in polemical, ideological and propagandist contexts". Experts disagree about "whether terrorism is wrong by definition or just wrong as a matter of fact; they disagree about whether terrorism should be defined in terms of its aims, or its methods, or both, or neither; they disagree about whether states can perpetrate terrorism; they even disagree about the importance or otherwise of ''terror'' for a definition of ''terrorism''."

has been slow to formulate a universally agreed, legally binding definition of this crime. These difficulties arise from the fact that the term "terrorism" is politically and emotionally charged. In this regard, Angus Martyn, briefing the Australian parliament, stated,
The international community has never succeeded in developing an accepted comprehensive definition of terrorism. During the 1970s and 1980s, the United Nations attempts to define the term floundered mainly due to differences of opinion between various members about the use of violence in the context of conflicts over national liberation and self-determination.Angus Martyn

U.S. law

Various legal systems and government agencies use different definitions of terrorism in their national legislation. U.S. Code Title 22 Chapter 38, Section 2656f(d) defines terrorism as: "Premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents". 18 U.S.C. § 2331 defines "international terrorism" and "domestic terrorism" for purposes of Chapter 113B of the Code, entitled "Terrorism": "International terrorism" means activities with the following three characteristics:

Terrorist acts frequently have a political purpose.

History

Depending on how broadly the term is defined, the roots and practice of terrorism can be traced at least to the 1st century AD. According to the contemporary Jewish-Roman historian
Josephus Flavius Josephus (; grc-gre, Ἰώσηπος, ; 37 – 100) was a first-century Romano-Jewish historian and military leader, best known for ''The Jewish War'', who was born in Jerusalem—then part of Roman Judea—to a father of priestly d ...

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

A number of theories have been advanced as to why this has happened. * Quasi-terrorism – The activities incidental to the commission of crimes of violence that are similar in form and method to genuine terrorism but which nevertheless lack its essential ingredient. It is not the main purpose of the quasi-terrorists to induce terror in the immediate victim as in the case of genuine terrorism, but the quasi-terrorist uses the modalities and techniques of the genuine terrorist and produces similar consequences and reaction. For example, the fleeing

It may be referred to as Structural Terrorism defined broadly as terrorist acts carried out by governments in pursuit of political objectives, often as part of their foreign policy.

* Social isolation * Perception that the cause responds to a profound injustice or indignity A report conducted by Paul Gill, John Horgan and Paige Deckert found that for "lone wolf" terrorists: * 43% were motivated by religious beliefs * 32% had pre-existing mental health disorders, while many more are found to have mental health problems upon arrest * At least 37% lived alone at the time of their event planning and/or execution, a further 26% lived with others, and no data were available for the remaining cases * 40% were unemployed at the time of their arrest or terrorist event * 19% subjectively experienced being disrespected by others * 14% percent experienced being the victim of verbal or physical assault Ariel Merari, a psychologist who has studied the psychological profiles of suicide terrorists since 1983 through media reports that contained biographical details, interviews with the suicides' families, and interviews with jailed would-be suicide attackers, concluded that they were unlikely to be psychologically abnormal. In comparison to economic theories of criminal behaviour, Scott Atran found that suicide terrorists exhibit none of the socially dysfunctional attributes—such as fatherless, friendless, jobless situations—or suicidal symptoms. By which he means, they do not kill themselves simply out of hopelessness or a sense of 'having nothing to lose'. Abrahm suggests that terrorist organizations do not select terrorism for its political effectiveness. Individual terrorists tend to be motivated more by a desire for social solidarity with other members of their organization than by political platforms or strategic objectives, which are often murky and undefined. Michael Mousseau shows possible relationships between the type of economy within a country and ideology associated with terrorism. Many terrorists have a history of domestic violence.

Perpetrators

The perpetrators of acts of terrorism can be individuals, groups, or states. According to some definitions, clandestine or semi-clandestine state actors may carry out terrorist acts outside the framework of a state of war. The most common image of terrorism is that it is carried out by small and secretive cells, highly motivated to serve a particular cause and many of the most deadly operations in recent times, such as the

to succeed where others had failed. Over the years, much research has been conducted to distill a terrorist profile to explain these individuals' actions through their psychology and socio-economic circumstances. Others, like Roderick Hindery, have sought to discern profiles in the propaganda tactics used by terrorists. Some security organizations designate these groups as ''violent non-state actors''. A 2007 study by economist Alan B. Krueger found that terrorists were less likely to come from an impoverished background (28 percent versus 33 percent) and more likely to have at least a high-school education (47 percent versus 38 percent). Another analysis found only 16 percent of terrorists came from impoverished families, versus 30 percent of male Palestinians, and over 60 percent had gone beyond high school, versus 15 percent of the populace.A study into the poverty-stricken conditions and whether terrorists are more likely to come from here,show that people who grew up in these situations tend to show aggression and frustration towards others. This theory is largely debated for the simple fact that just because one is frustrated,does not make them a potential terrorist. To avoid detection, a terrorist will look, dress, and behave normally until executing the assigned mission. Some claim that attempts to profile terrorists based on personality, physical, or sociological traits are not useful. The physical and behavioral description of the terrorist could describe almost any normal person.Library of Congress

State sponsors

A state can sponsor terrorism by funding or harboring a terrorist group. Opinions as to which acts of violence by states consist of state-sponsored terrorism vary widely. When states provide funding for groups considered by some to be terrorist, they rarely acknowledge them as such.


State terrorism

As with "terrorism" the concept of "state terrorism" is controversial. The Chairman of the United Nations Counter-Terrorism Committee has stated that the committee was conscious of 12 international conventions on the subject, and none of them referred to state terrorism, which was not an international legal concept. If states abused their power, they should be judged against international conventions dealing with war crimes,

has said that it is "time to set aside debates on so-called 'state terrorism'. The use of force by states is already thoroughly regulated under international law". he made clear that, "regardless of the differences between governments on the question of the definition of terrorism, what is clear and what we can all agree on is that any deliberate attack on innocent civilians r non-combatants regardless of one's cause, is unacceptable and fits into the definition of terrorism." State terrorism has been used to refer to terrorist acts committed by governmental agents or forces. This involves the use of state resources employed by a state's foreign policies, such as using its military to directly perform acts of terrorism. Professor of Political Science Michael Stohl cites the examples that include the German bombing of London, the

Connection with tourism

The connection between terrorism and tourism has been widely studied since the
Luxor massacre The Luxor massacre was the killing of 62 people, mostly tourists, on 17 November 1997, at Deir el-Bahari, an archaeological site and major tourist attraction across the Nile from Luxor, Egypt. Attack Deir el-Bahari is one of Egypt's top touri ...
in Egypt. In the 1970s, the targets of terrorists were politicians and chiefs of police while now, international tourists and visitors are selected as the main targets of attacks. The attacks on the World Trade Center and the Pentagon on September 11, 2001, were the symbolic center, which marked a new epoch in the use of civil transport against the main power of the planet. From this event onwards, the spaces of leisure that characterized the pride of West were conceived as dangerous and frightful.

will not be effective because opposing forces vary greatly in power. Yuval Harari argues that the peacefulness of modern states makes them paradoxically more vulnerable to terrorism than pre-modern states. Harari argues that because modern states have committed themselves to reducing political violence to almost zero, terrorists can, by creating political violence, threaten the very foundations of the legitimacy of the modern state. This is in contrast to pre-modern states, where violence was a routine and recognised aspect of politics at all levels, making political violence unremarkable. Terrorism thus shocks the population of a modern state far more than a pre-modern one and consequently the state is forced to overreact in an excessive, costly and spectacular manner, which is often what the terrorists desire. The type of people terrorists will target is dependent upon the ideology of the terrorists. A terrorist's ideology will create a class of "legitimate targets" who are deemed as its enemies and who are permitted to be targeted. 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: *

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). There are several academic journals devoted to the field, including ''Perspectives on Terrorism''.


International agreements

One of the agreements that promote the international legal anti-terror framework is the Code of Conduct Towards Achieving a World Free of Terrorism that was adopted at the 73rd session of the United Nations General Assembly in 2018. The Code of Conduct was initiated by Kazakhstan President Nursultan Nazarbayev. Its main goal is to implement a wide range of international commitments to counter terrorism and establish a broad global coalition towards achieving a world free of terrorism by 2045. The Code was signed by more than 70 countries.


Response in the United States

According to a report by Dana Priest and William M. Arkin in The Washington Post, "Some 1,271 government organizations and 1,931 private companies work on programs related to counterterrorism, homeland security and intelligence in about 10,000 locations across the United States." America's thinking on how to defeat radical Islamists is split along two very different schools of thought. Republicans, typically follow what is known as the Bush Doctrine, advocate the military model of taking the fight to the enemy and seeking to democratize the Middle East. Democrats, by contrast, generally propose the law enforcement model of better cooperation with nations and more security at home.Ankony, Robert C., "A New Strategy for America's War on Terrorism", ''Patrolling'' magazine, 75th Ranger Regiment Association, Winter 2011, 56–57. In the introduction of the ''U.S. Army / Marine Corps Counterinsurgency Field Manual'', Sarah Sewall states the need for "U.S. forces to make securing the civilian, rather than destroying the enemy, their top priority. The civilian population is the center of gravity—the deciding factor in the struggle.... Civilian deaths create an extended family of enemies—new insurgent recruits or informants—and erode support of the host nation." Sewall sums up the book's key points on how to win this battle: "Sometimes, the more you protect your force, the less secure you may be.... Sometimes, the more force is used, the less effective it is.... The more successful the counterinsurgency is, the less force can be used and the more risk must be accepted.... Sometimes, doing nothing is the best reaction." This strategy, often termed "courageous restraint", has certainly led to some success on the Middle East battlefield. However, it does not address the fact that terrorists are mostly homegrown.


Mass media

Mass media exposure may be a primary goal of those carrying out terrorism, to expose issues that would otherwise be ignored by the media. Some consider this to be manipulation and exploitation of the media. The Internet has created a new way for groups to spread their messages. This has created a cycle of measures and counter measures by groups in support of and in opposition to terrorist movements. The United Nations has created its own online counter-terrorism resource. The mass media will, on occasion, censor organizations involved in terrorism (through self-restraint or regulation) to discourage further terrorism. This may encourage organizations to perform more extreme acts of terrorism to be shown in the mass media. Conversely James F. Pastor explains the significant relationship between terrorism and the media, and the underlying benefit each receives from the other. Former Prime Minister of the United Kingdom, British Prime Minister Margaret Thatcher famously spoke of the close connection between terrorism and the media, calling publicity 'the oxygen of terrorism'.


Outcome of terrorist groups

Jones and Libicki (2008) created a list of all the terrorist groups they could find that were active between 1968 and 2006. They found 648. Of those, 136 splintered and 244 were still active in 2006. Of the ones that ended, 43 percent converted to nonviolent political actions, like the Good Friday Agreement, Irish Republican Army in Northern Ireland. Law enforcement took out 40 percent. Ten percent won. Only 20 groups, 7 percent, were destroyed by military force. Forty-two groups became large enough to be labeled an insurgency; 38 of those had ended by 2006. Of those, 47 percent converted to nonviolent political actors. Only 5 percent were ended by law enforcement. Twenty-six percent won. Twenty-one percent succumbed to military force. Jones and Libicki concluded that military force may be necessary to deal with large insurgencies but are only occasionally decisive, because the military is too often seen as a bigger threat to civilians than the terrorists. To avoid that, the rules of engagement must be conscious of collateral damage and work to minimize it. Another researcher, Audrey Cronin, lists six primary ways that terrorist groups end: # Capture or killing of a group's leader. (Decapitation). # Entry of the group into a legitimate political process. (Negotiation). # Achievement of group aims. (Success). # Group implosion or loss of public support. (Failure). # Defeat and elimination through brute force. (Repression). # Transition from terrorism into other forms of violence. (Reorientation).
