War on terrorThe war on terror, officially the Global War on Terrorism (GWOT), is a global counterterrorism military campaign initiated by the United States following the September 11 attacks and is also the most recent global conflict spanning multiple wars. The main targets of the campaign were militant Islamist and Salafi jihadist armed organisations such as al-Qaeda, the Islamic State, and their international affiliates, which were waging military insurgencies to overthrow governments of various Muslim-majority countries.
TerrorismTerrorism, in its broadest sense, is the use of intentional violence and fear to achieve political or ideological aims. The term is used in this regard primarily to refer to intentional violence during peacetime or in the context of war against non-combatants (mostly civilians and neutral military personnel). The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but became widely used internationally and gained worldwide attention in the 1970s during the Troubles in Northern Ireland, the Basque conflict, and the Israeli–Palestinian conflict.
State-sponsored terrorismState-sponsored terrorism is terrorist violence carried out with the active support of national governments provided to violent non-state actors. States can sponsor terrorist groups in several ways, including but not limited to funding terrorist organizations, providing training, supplying weapons, providing other logistical and intelligence assistance, and hosting groups within their borders. Because of the pejorative nature of the word, the identification of particular examples are often subject to political dispute and different definitions of terrorism.
Violent non-state actorIn international relations, violent non-state actors (VNSAs), also known as non-state armed actors or non-state armed groups (NSAGs), are individuals or groups that are wholly or partly independent of governments and which threaten or use violence to achieve their goals. VNSAs vary widely in their goals, size, and methods. They may include narcotics cartels, popular liberation movements, religious and ideological organizations, corporations (e.g.
State terrorismState terrorism refers to acts of terrorism which a state conducts against another state or against its own citizens. Definition of terrorism and Terrorism There is neither an academic nor an international legal consensus regarding the proper definition of the word "terrorism". Some scholars believe the actions of governments can be labelled "terrorism".
Domestic terrorismDomestic terrorism or homegrown terrorism is a form of terrorism in which victims "within a country are targeted by a perpetrator with the same citizenship" as the victims. There are many definitions of terrorism, and none of them are universally accepted. While there are many potential definitions of domestic terrorism, it is largely defined as terrorism in which the perpetrator targets his/her own country. Enders defines domestic terrorism as "homegrown in which the venue, target, and perpetrators are all from the same country.
Asymmetric warfareAsymmetric warfare (or asymmetric engagement) is a type of war between belligerents whose relative military power, strategy, or tactics differ significantly. This type of warfare often, but not necessarily, involves insurgents or resistance movement militias who may have the status of unlawful combatants against a standing army. Asymmetrical warfare can also describe a conflict in which belligerents' resources are uneven, and consequently, they both may attempt to exploit each other's relative weaknesses.
CounterterrorismCounterterrorism (also spelled counter-terrorism), also known as anti-terrorism, relates to the practices, military tactics, techniques, and strategies that governments, law enforcement, businesses, and intelligence agencies use to combat or eliminate terrorism. If an act of terrorism occurs as part of a broader insurgency, and insurgency is included in the definition of terrorism, then counterterrorism may additionally employ counterinsurgency measures.
Resistance movementA resistance movement is an organized group of people that tries to resist the government or an occupying power, causing disruption and unrest in civil order and stability. Such a movement may seek to achieve its goals through either the use of nonviolent resistance (sometimes called civil resistance), or the use of force, whether armed or unarmed. In many cases, as for example in the United States during the American Revolution, or in Norway in the Second World War, a resistance movement may employ both violent and non-violent methods, usually operating under different organizations and acting in different phases or geographical areas within a country.
September 11 attacksThe September 11 attacks, commonly known as 9/11, were four coordinated Islamist suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, 19 terrorists hijacked four commercial airliners scheduled to travel from the New England and Mid-Atlantic regions of the East Coast to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, two of the world's five-tallest buildings at the time, and aimed the next two flights toward targets in or near Washington, D.
