Casus belliA casus belli (; ) is an act or an event that either provokes or is used to justify a war. A casus belli involves direct offenses or threats against the nation declaring the war, whereas a casus foederis involves offenses or threats against its ally—usually one bound by a mutual defense pact. Either may be considered an act of war. A declaration of war usually contains a description of the casus belli that has led the party in question to declare war on another party.
Fear, uncertainty, and doubtFear, uncertainty and doubt (often shortened to FUD) is a manipulative propaganda tactic used in sales, marketing, public relations, politics, polling and cults. FUD is generally a strategy to influence perception by disseminating negative and dubious or false information, and is a manifestation of the appeal to fear. The term "fear, uncertainty and doubt" appeared as far back as the 1920s, whereas the similar formulation "doubts, fears and uncertainties" reaches back to 1693.
AssassinationAssassination is the willful killing, by a sudden or secret attack, of a personespecially if prominent or important. It may be prompted by grievances, notoriety, financial, military, political or other motives. Many times governments, corporations, organized crime or their agents order assassinations. Acts of assassination have been performed since ancient times. A person who carries out an assassination is called an assassin or hitman.
PerfidyIn the context of war, perfidy is a form of deception in which one side promises to act in good faith (such as by raising a flag of truce) with the intention of breaking that promise once the unsuspecting enemy is exposed (such as by coming out of cover to take the "surrendering" prisoners into custody). Perfidy constitutes a breach of the laws of war and so is a war crime, as it degrades the protections and mutual restraints developed in the interest of all parties, combatants and civilians.
Russo-Ukrainian WarThe Russo-Ukrainian War is an ongoing international conflict between Russia, alongside Russian-backed separatists, and Ukraine, which began in February 2014. Following Ukraine's Revolution of Dignity, Russia annexed Crimea from Ukraine and supported pro-Russian separatists fighting the Ukrainian military in the Donbas war. The first eight years of conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, Russia launched a full-scale invasion of Ukraine.
Q-shipQ-ships, also known as Q-boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q-ships the chance to open fire and sink them. The use of Q-ships contributed to the abandonment of cruiser rules restricting attacks on unarmed merchant ships and to the shift to unrestricted submarine warfare in the 20th century.
Summary executionA summary execution is an execution in which a person is accused of a crime and immediately killed without the benefit of a full and fair trial. Executions as the result of summary justice (such as a drumhead court-martial) are sometimes included, but the term generally refers to capture, accusation, and execution all conducted within a very short period of time, and without any trial. Under international law, refusal to accept lawful surrender in combat and instead killing the person surrendering is also categorized as a summary execution (as well as murder).
Operation GladioOperation Gladio was the codename for clandestine "stay-behind" operations of armed resistance that were organized by the Western Union (WU) (founded in 1948), and subsequently by NATO (formed in 1949) and by the CIA (established in 1947), in collaboration with several European intelligence agencies during the Cold War. Although "Gladio" specifically refers to the Italian branch of the NATO stay-behind organizations, "Operation Gladio" is used as an informal name for all of them.
Psychological warfarePsychological warfare (PSYWAR), or the basic aspects of modern psychological operations (PsyOp), have been known by many other names or terms, including Military Information Support Operations (MISO), Psy Ops, political warfare, "Hearts and Minds", and propaganda. The term is used "to denote any action which is practiced mainly by psychological methods with the aim of evoking a planned psychological reaction in other people". Various techniques are used, and are aimed at influencing a target audience's value system, belief system, emotions, motives, reasoning, or behavior.
