No definition of terrorism has gained universal agreement. Challenges emerge due to the politically and emotionally charged nature of the term, the double standards used in applying it, and disagreement over the nature of terrorist acts and limits of the right to self-determination. Harvard law professor Richard Baxter, a leading expert on the law of war, was a skeptic: "We have cause to regret that a legal concept of 'terrorism' was ever inflicted upon us. The term is imprecise; it is ambiguous; and above all, it serves no operative legal purpose."
Different legal systems and government agencies employ diverse definitions of terrorism, with governments showing hesitation in establishing a universally accepted, legally binding definition. Title 18 of the United States Code defines terrorism as acts that are intended to intimidate or coerce civilians or government. The international community has been slow to formulate a universally agreed, legally binding definition of this crime, and has been unable to conclude a Comprehensive Convention on International Terrorism that incorporates a single, all-encompassing, legally binding, criminal law definition of terrorism. These difficulties arise from the fact that the term "terrorism" is politically and emotionally charged. The international community has instead adopted a series of sectoral conventions that define and criminalize various types of terrorist activities.
Rapoport proposed three case studies to demonstrate "ancient lineage" of religious terrorism, which he called "sacred terror": the "Thugs", the Assassins and the Jewish Sicarii Zealots. Rapoport argued religious terrorism has been ongoing since ancient times and that "there are signs that it is reviving in new and unusual forms". He is the first to propose that religious doctrines were more important than political rationales for some terrorist groups. Rapoport's work has since become the basis of the model of "New Terrorism" proposed by Bruce Hoffman and developed by other scholars. "New Terrorism" has had an unparalleled impact on policymaking. Critics have pointed out that the model is politically charged and over-simplified. The underlying historical assertions have received less critical attention. According to The Oxford Handbook on the History of Terrorism:
Depending on the country, the political system, and the time in history, the types of terrorism are varying.
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 seven categories:
Other sources have defined the typology of terrorism in different ways, for example, broadly classifying it into domestic terrorism and international terrorism, or using categories such as vigilante terrorism or insurgent terrorism. Some ways the typology of terrorism may be defined are:
Terrorist acts frequently have a political purpose based on self-determination claims, ethnonationalist frustrations, single issue causes (like abortion or the environment), or other ideological or religious causes that terrorists claim are a moral justification for their violent acts.
Attacks on "collaborators" are used to intimidate people from cooperating with the state in order to undermine state control. This strategy was used in Ireland, in Kenya, in Algeria and in Cyprus during their independence struggles.
Sometimes terrorists on the same side fight for different reasons. For example, in the Chechen–Russian conflict secular Chechens using terrorist tactics fighting for national independence are allied with radical Islamist terrorists who have arrived from other countries.
Various personal and social factors may influence the personal choice of whether to join a terrorist group or attempt an act of terror, including:
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.[example needed] Many terrorists have a history of domestic violence.
Terrorism is most common in nations with intermediate political freedom, and it is least common in the most democratic nations.
According to Boaz Ganor, "Modern terrorism sees the liberal democratic state, in all its variations, as the perfect launching pad and a target for its attacks. Moreover, some terrorist organizations—particularly Islamist-jihadist organizations—have chosen to cynically exploit democratic values and institutions to gain power and status, promote their interests, and achieve internal and international legitimacy". Jihadist militants have shown an ambivalent view towards democracy, as they both exploit it for their ends and oppose it in their ideology. Various quotes from jihadist leaders note their disdain for democracy and their efforts to undermine it in favor of Islamic rule. Democracies, such as Japan, the United Kingdom, the United States, Israel, Indonesia, India, Spain, Germany, Italy and the Philippines, have all experienced domestic terrorism.
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 September 11 attacks, the London underground bombing, 2008 Mumbai attacks and the 2002 Bali bombings were planned and carried out by a close clique, composed of close friends, family members and other strong social networks. These groups benefited from the free flow of information and efficient telecommunications 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. Some specialists highlight the lack of evidence supporting the idea that terrorists are typically psychologically disturbed. The careful planning and detailed execution seen in many terrorist acts are not characteristics generally associated with mentally unstable individuals. 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.
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. The majority of terrorist attacks are carried out by military age men, aged 16 to 40.
Groups not part of the state apparatus of in opposition to the state are most commonly referred to as a "terrorist" in the media.
Terrorist attacks are often targeted to maximize fear and publicity, most frequently using explosives.
Terrorist groups usually methodically plan attacks in advance, and may train participants, plant undercover agents, and raise money from supporters or through organized crime. Communications occur through modern telecommunications, or through old-fashioned methods such as couriers. There is concern about terrorist attacks employing weapons of mass destruction. Some academics have argued that while it is often assumed terrorism is intended to spread fear, this is not necessarily true, with fear instead being a by-product of the terrorist's actions, while their intentions may be to avenge fallen comrades or destroy their perceived enemies.
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.
Terrorists may attempt to use the media to spread their message or manipulate their target audience. Shamil Basayev used this tactic during the Budyonnovsk hospital hostage crisis and again in the Moscow theater hostage crisis. Terrorists may also target national symbols for attention. Walter Lacquer wrote that "terrorism was always, to a large extent, about public relations and propaganda ('Propaganda by Deed' had been the slogan in the nineteenth century)".
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 counterterrorism 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:
One of the agreements that promote the international legal counterterrorist 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 counterterrorism and establish a broad global coalition towards achieving a world free of terrorism by 2045. The Code was signed by more than 70 countries.
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. 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.
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% converted to nonviolent political actions, like the Irish Republican Army in Northern Ireland; 40% were defeated by law enforcement; 7% (20 groups) were defeated by military force; and 10% succeeded.
42 groups became large enough to be labeled an insurgency; 38 of those had ended by 2006. Of those, 47% converted to nonviolent political actors. Only 5% were ended by law enforcement, and 21% were defeated by military force. 26% won. 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:
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, international human rights law, and international humanitarian law. Former United Nations Secretary-General Kofi Annan 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 [or 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 Japanese surprise attack on Pearl Harbor, the Allied firebombing of Dresden, and the U.S. atomic bombings of Hiroshima and Nagasaki during World War II. He argues that "the use of terror tactics is common in international relations and the state has been and remains a more likely employer of terrorism within the international system than insurgents." He cites the first strike option as an example of the "terror of coercive diplomacy" as a form of this, which holds the world hostage with the implied threat of using nuclear weapons in "crisis management" and he argues that the institutionalized form of terrorism has occurred as a result of changes that took place following World War II. In this analysis, state terrorism exhibited as a form of foreign policy was shaped by the presence and use of weapons of mass destruction, and the legitimizing of such violent behavior led to an increasingly accepted form of this behavior by the state.
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.
Media outlets who wish to convey impartiality may limit their usage of "terrorist" and "terrorism" because they are loosely defined, potentially controversial in nature, and subjective terms.
The term "terrorism" is often used to abuse or denounce opposite parties, either governments or non-state groups. An example of this is the terruqueo political attack used by right-wing groups in Peru to target leftist groups or those opposed to the neoliberal status quo, likening opponents to guerrilla organizations from the internal conflict in Peru.
Those labeled "terrorists" by their opponents rarely identify themselves as such, but it was not always so. While a multitude of terms like separatist, freedom fighter, liberator, revolutionary, vigilante, militant, paramilitary, guerrilla, rebel, patriot, have come into use, (including some culturally specific terms borrowed from other languages like Jihadi, mujahideen, and fedayeen), the unwillingness to self-identify as terrorists began when parties in a conflict started to describe each other as terrorists pejoratively. As an example, when Vera Zasulich attacked a Russian official known for abusing prisoners she told the court "I am not a criminal, I am a terrorist!". The stunned court acquitted Zazulich when they realized that she was trying to become a martyr. She was carried out of the courtroom on the shoulders of the crowd.
Some groups and individuals have openly admitted to using "terrorist tactics" even while maintaining distance from the pejorative term in their self-descriptions. The Zionist militant group Lohamei Herut Yisrael admitted that they used terrorist tactics but used the euphemism "Freedom Fighters" to describe themselves (Lohamei Herut Yisrael means "Freedom Fighters for Israel".)
Groups accused of terrorism understandably prefer terms reflecting legitimate military or ideological action. Leading terrorism researcher Professor Martin Rudner, director of the Canadian Centre of Intelligence and Security Studies at Ottawa's Carleton University, defines "terrorist acts" as unlawful attacks for political or other ideological goals, and said:
Labelling opponents as "terrorists" has been used as a tactic to evade the usual laws of war against things such as assassinations and other extrajudicial killing, particularly by Israel and the United States.[better source needed][attribution needed] Some international legal opinions suggest that terrorist activities by their very nature "deny" the civilian nature of an ostensibly civilian participant.
Some groups, when involved in a "liberation" struggle, have been called "terrorists" by the Western governments or media. Later, these same persons, as leaders of the liberated nations, are called "statesmen" by similar organizations. Two examples of this phenomenon are the Nobel Peace Prize laureates Menachem Begin and Nelson Mandela. WikiLeaks editor Julian Assange has been called a "terrorist" by Sarah Palin and Joe Biden.

"The ordinary current use of the word terrorism is much too wide. That is to say, if we list all the different phenomena which are at one time or another described as terrorism in ordinary conversation, or in ordinary newspapers, or by ordinary politicians, we will end up with a huge rag-bag of not very similar items . . The disadvantages of trying to construct an ordinary-language definition based on current usage can be seen, too, in the plethora of conflicting definitions occurring in philosophical and political literature. Thus philosophers for instance disagree about whether or not terrorism is wrong by definition or wrong just 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 or not states can perpetrate terrorism; they even disagree about the importance or otherwise of terror for a definition of terrorism."

Clark, David S. (2007). Encyclopedia of Law and Society. United Kingdom: Sage. p. 1474. Before the advent of dynamite and automatic weapons, groups had to kill on a one-to-one basis. It took one terrorist (or soldier) to kill one enemy or perhaps a handful of enemies, except in unusual cases, such as the failed 1605 Gunpowder Plot of Guy Fawkes in England. The weapons of choice for the earlier terrorists were the dagger, the noose, the sword and the poison elixir. This changed with the hand-thrown bomb and the pistol, introduced in the nineteenth century, and the machine gun and plastic explosives, common in the twentieth century. /wiki/1605_Gunpowder_Plot

Rapoport, D. (1984) "Fear and Trembling" in Mahan, S., Griset, P. L. (2012). Terrorism in Perspective. United Kingdom: Sage Publications:"Furthermore, the three cases illustrate a kind of terror nowhere adequately analyzed in our theoretical literature, terror designated here as holy or sacred. Before the nineteenth century, religion provided the only acceptable justifications for terror, and the differences between sacred and modern expressions (differences of nature, not scale) raise questions about the appropriateness of contemporary definitions. The holy terrorist believes that only a transcendental purpose which fulfills the meaning of the universe can justify terror, and that the deity reveals at some early moment in both time and end the means and may even participate in the process as well. We see terrorists as free to seek different political ends in this world by whatever means of terror they consider most appropriate."
Laqueur 2001: "The misunderstandings about the nature of terrorism in the 1970s were founded, in part, on political reasons. At the time, terrorism was predominantly left wing in inspiration and it did not come as a surprise that commentators belonging to the same political persuasion would produce theoretical explanations which were, at the very least, not unsympathetic as far as terrorists were concerned. It was argued in these circles that terrorism always occurred where there was oppression, social or national, that the terrorists had genuine, legitimate grievances—hence the conclusion that once the grievances were eradicated, terrorism would also disappear. Terrorism, in brief, was seen as a revolutionary phenomenon; it was carried out by poor and desperate human beings and had, therefore, to be confronted with sympathetic understanding." - Laqueur, Walter (2001).

"For the Israeli commander on the ground, the meaning of terrorism has become increasingly vague and contradictory. This problem is both generic and, because of the Oslo Accords,2 Israel-specific . . the term is increasingly losing all operational precision. . . Significantly, despite the growing volume of academic publications dealing with terrorism, little, if any, serious progress has been made in suitably clarifying that concept, in distinguishing it clearly from various other uses of force in world politics and from other related crimes under international law. Indeed, judging from the standard definitions of terrorism now in "professional" use, definitions that offer little or no operational benefit for scholars or for tactical commanders, the term has become so comprehensive and vague that it embraces even the most discrepant and unintended activities.", Louis René Beres, "Law and Politics in Israel: What Terrorism Means for the IDF Commander", Brown Journal of World Affairs , Summer/Fall 1997, Vol. 4, No. 2, pp. 257–276. /wiki/Louis_Ren%C3%A9_Beres
