Fifth columnA fifth column is any group of people who undermine a larger group or nation from within, usually in favor of an enemy group or another nation. According to Harris Mylonas and Scott Radnitz, "fifth columns" are "domestic actors who work to undermine the national interest, in cooperation with external rivals of the state." The activities of a fifth column can be overt or clandestine. Forces gathered in secret can mobilize openly to assist an external attack. This term is also extended to organised actions by military personnel.
False flagA false flag operation is an act committed with the intent of disguising the actual source of responsibility and pinning blame on another party. The term "false flag" originated in the 16th century as an expression meaning an intentional misrepresentation of someone's allegiance. The term was famously used to describe a ruse in naval warfare whereby a vessel flew the flag of a neutral or enemy country in order to hide its true identity. The tactic was originally used by pirates and privateers to deceive other ships into allowing them to move closer before attacking them.
United Nations Security CouncilThe United Nations Security Council (UNSC) is one of the six principal organs of the United Nations (UN) and is charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with the authority to issue binding resolutions on member states.
Donetsk OblastDonetsk Oblast (Donetska oblast, doˈnɛtsjkɐ ˈɔblɐsjtj), also referred to as Donechchyna (Донеччина, doˈnɛtʃːɪnɐ), is an oblast in eastern Ukraine. It is Ukraine's most populous province, with around 4.1 million residents. Its administrative centre is Donetsk, though due to the ongoing Russo-Ukrainian War, the regional administration was moved to Kramatorsk. Historically, the region has been an important part of the Donbas region. From its creation in 1938 until November 1961, it bore the name Stalino Oblast as Donetsk was then named "Stalino", in honour of Joseph Stalin.
Martial lawMartial law is the replacement of civilian government by military rule and the suspension of civilian legal processes for military powers. Martial law can continue for a specified amount of time, or indefinitely, and standard civil liberties may be suspended for as long as martial law continues. Most often, martial law is declared in times of war and/or emergencies such as civil unrest and natural disasters. Alternatively, martial law may be declared in instances of military coup d'états.
Conventional warfareConventional warfare is a form of warfare conducted by using conventional weapons and battlefield tactics between two or more states in open confrontation. The forces on each side are well-defined and fight by using weapons that target primarily the opponent's military. It is normally fought by using conventional weapons, not chemical, biological, radiological, or nuclear weapons. The general purpose of conventional warfare is to weaken or destroy the opponent's military, which negates its ability to engage in conventional warfare.
Colour revolutionColour revolution (sometimes coloured revolution) is a term used since early 2000s primarily to describe a series of nonviolent protests and accompanying (attempted or successful) changes of government that took place in post-Soviet states (particularly Georgia, Ukraine, and Kyrgyzstan) and Federal Republic of Yugoslavia. The aim of the colour revolutions was to establish Western-style liberal democracy in those countries and eliminate corruption. They were primarily triggered by the election results widely viewed as falsified.
War of aggressionA war of aggression, sometimes also war of conquest, is a military conflict waged without the justification of self-defense, usually for territorial gain and subjugation. Wars without international legality (i.e. not out of self-defense nor sanctioned by the United Nations Security Council) can be considered wars of aggression; however, this alone usually does not constitute the definition of a war of aggression; certain wars may be unlawful but not aggressive (a war to settle a boundary dispute where the initiator has a reasonable claim, and limited aims, is one example).
Sea of AzovThe Sea of Azov (Crimean Tatar: Azaq deñizi; Azovskoye more; Azovs'ke more) is an inland shelf sea in Eastern Europe connected to the Black Sea by the narrow (about ) Strait of Kerch, and is sometimes regarded as a northern extension of the Black Sea. The sea is bounded by Russia on the east, and by Ukraine on the northwest and southwest, currently under Russian occupation. It is an important access route for Central Asia, from the Caspian Sea via the Volga-Don Canal.
Dissolution of the Soviet UnionThe dissolution of the Soviet Union was the process of internal disintegration within the Soviet Union (USSR), which resulted in the end of the existence of the country and of its federal government as a sovereign state, which in turn resulted in its 15 constituent republics gaining full independence on 26 December 1991. It brought an end to General Secretary (also President) Mikhail Gorbachev's effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide.
