Terrorism in the context of "Contentious politics"

The Central Intelligence Agency (CIA /ˌsiː.aɪˈeɪ/) is a civilian foreign intelligence service of the federal government of the United States tasked with advancing national security through collecting and analyzing intelligence from around the world and conducting covert operations. The agency is headquartered in the George Bush Center for Intelligence in Langley, Virginia, and is sometimes metonymously called "Langley". A major member of the United States Intelligence Community (IC), the CIA has reported to the director of national intelligence since 2004, and is focused on providing intelligence for the president and the Cabinet, though it also provides intelligence for a variety of other entities including the US Military and foreign allies.

The CIA is headed by a director and is divided into various directorates, including a Directorate of Analysis and Directorate of Operations. Unlike the Federal Bureau of Investigation (FBI), the CIA has no law enforcement function and focuses on intelligence gathering overseas, with only limited domestic intelligence collection. The CIA is responsible for coordinating all human intelligence (HUMINT) activities in the IC. It has been instrumental in establishing intelligence services in many countries, and has provided support to many foreign organizations. The CIA exerts foreign political influence through its paramilitary operations units, including its Special Activities Center. It has also provided support to several foreign political groups and governments, including planning, coordinating, training and carrying out torture, and technical support. It was involved in many regime changes and carrying out planned assassinations of foreign leaders and terrorist attacks against civilians.

Energy supply is the delivery of fuels or transformed fuels to point of consumption. It potentially encompasses the extraction, transmission, generation, distribution and storage of fuels. It is also sometimes called energy flow.

This supply of energy can be disrupted by several factors, including imposition of higher energy prices due to action by OPEC or other cartel, war, political disputes, economic disputes, or physical damage to the energy infrastructure due to terrorism. The security of the energy supply is a major concern of national security and energy law.

Capital punishment, also known as the death penalty and formerly called judicial homicide, is the state-sanctioned killing of a person as punishment for actual or supposed misconduct. The sentence ordering that an offender be punished in such a manner is called a death sentence, and the act of carrying out the sentence is an execution. A prisoner who has been sentenced to death and awaits execution is condemned and is commonly referred to as being "on death row". Etymologically, the term capital (lit. 'of the head', derived via the Latin capitalis from caput, "head") refers to execution by beheading, but executions are carried out by many methods.

Crimes that are punishable by death are known as capital crimes, capital offences, or capital felonies, and vary depending on the jurisdiction, but commonly include serious crimes against a person, such as murder, assassination, mass murder, child murder, aggravated rape, terrorism, aircraft hijacking, war crimes, crimes against humanity, and genocide, along with crimes against the state such as attempting to overthrow government, treason, espionage, sedition, and piracy. Also, in some cases, acts of recidivism, aggravated robbery, and kidnapping, in addition to drug trafficking, drug dealing, and drug possession, are capital crimes or enhancements. However, states have also imposed punitive executions, for an expansive range of conduct, for political or religious beliefs and practices, for a status beyond one's control, or without employing any significant due process procedures. Judicial murder is the intentional and premeditated killing of an innocent person by means of capital punishment. For example, the executions following the show trials in the Soviet Union during the Great Purge of 1936–1938 were an instrument of political repression.

The Sahel region (/səˈhɛl/; from Arabic ساحل (sāḥil [ˈsaːħil]) 'coast, shore'), or Sahelian acacia savanna, is a biogeographical region in Africa. It is the transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a hot semi-arid climate and stretches across the southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea. Although geographically located in the tropics, the Sahel does not have a tropical climate.

Especially in the western Sahel, there are frequent shortages of food and water due to its very high government corruption and the semi-arid climate. Nonetheless the region has sustained very high human birthrates, resulting in a rapid increase in population. In recent times, various coups, insurgencies, terrorism and foreign interventions have taken place in many Sahel countries, especially across former Françafrique.

The Cuban Missile Crisis, also known as the October Crisis (Spanish: Crisis de Octubre) in Cuba, or the Caribbean Crisis (Russian: Карибский кризис, romanized: Karibskiy krizis), was a 13-day confrontation between the governments of the United States and the Soviet Union, when American deployments of nuclear missiles in the United Kingdom, Italy and Turkey were matched by Soviet deployments of nuclear missiles in Cuba. The crisis lasted from 16 to 28 October 1962. The confrontation is widely considered the closest the Cold War came to escalating into full-scale nuclear war.

From 1959, the US government based Thor nuclear missiles in England, known as Project Emily. In 1961, the US put Jupiter nuclear missiles in Italy and Turkey. All were within range of Moscow. The US had trained a paramilitary force of Cuban expatriates, which the CIA led in an attempt to invade Cuba and overthrow its government. Starting in November of that year, the US government engaged in a violent campaign of terrorism and sabotage in Cuba, referred to as the Cuban Project, which continued throughout the first half of the 1960s. The Soviet administration was concerned about a Cuban drift towards China, with which the Soviets had an increasingly fractious relationship. In response to these factors the Soviet and Cuban governments agreed, at a meeting between leaders Nikita Khrushchev and Fidel Castro in July 1962, to place nuclear missiles on Cuba to deter a future US invasion. Construction of launch facilities started shortly thereafter.

National security, or national defence (national defense in American English), is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, such as the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other states, action by violent non-state actors, by narcotic cartels, organized crime, by multinational corporations, and also the effects of natural disasters.

Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes of insecurity, such as climate change, economic inequality, political exclusion, and nuclear proliferation.

The right to privacy is an element of various legal traditions that intends to restrain governmental and private actions that threaten the privacy of individuals. Over 185 national constitutions mention the right to privacy. Since the global surveillance disclosures of 2013, the right to privacy has been a subject of international debate. Government agencies, such as the NSA, FBI, CIA, R&AW, and GCHQ, have engaged in mass, global surveillance. Some current debates around the right to privacy include whether privacy can co-exist with the current capabilities of intelligence agencies to access and analyze many details of an individual's life; whether or not the right to privacy is forfeited as part of the social contract to bolster defense against supposed terrorist threats; and whether threats of terrorism are a valid excuse to spy on the general population. Private sector actors can also threaten the right to privacy – particularly technology companies, such as Amazon, Apple, Meta, Google, Microsoft, and Yahoo that use and collect personal data.

Guerrilla warfare is a type of unconventional warfare in which small groups of irregular military, such as rebels, partisans, paramilitary personnel or armed civilians, which may include children in the military, use ambushes, sabotage, terrorism, raids, petty warfare or hit-and-run tactics in a rebellion, in a violent conflict, in a war or in a civil war to fight against regular military, police or rival insurgent forces.

Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century, the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in The Art of War. The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy, and in China Peng Yue is also often regarded as the inventor of guerrilla warfare. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance against invading or occupying armies.
