War on Drugs: Revolutionary Armed Forces of Colombia (FARC) attack a military base in Guaviare, starting three weeks of guerrilla warfare in which at least 130 Colombians are killed.

The Revolutionary Armed Forces of ColombiaPeople's Army (Spanish: Fuerzas Armadas Revolucionarias de ColombiaEjrcito del Pueblo, FARCEP or FARC) is a MarxistLeninist guerrilla group involved in the continuing Colombian conflict starting in 1964. The FARCEP was formed during the Cold War period as a peasant force promoting a political line of agrarianism and anti-imperialism. They are known to employ a variety of military tactics, in addition to more unconventional methods, including terrorism.The operations of the FARCEP were funded by kidnap and ransom, illegal mining, extortion, and taxation of various forms of economic activity, and the production and distribution of illegal drugs. They are only one actor in a complex conflict where atrocities have been committed by the state, right-wing paramilitaries, and left-wing guerrillas not limited to FARC, such as ELN, M-19, and others. Colombia's National Centre for Historical Memory, a government agency, has estimated that between 1981 and 2012 paramilitary groups have caused 38.4% of the civilian deaths, while the Guerillas are responsible for 16.8%, 10.1% by the Colombian Security Forces and 27.7% by non-identified armed groups. The National Centre for Historical Memory has also concluded that of the 27,023 kidnappings carried out between 1970 and 2010, the Guerillas were responsible for 90.6% of them. The United Nations has estimated that 12% of all civilian deaths in the Colombian conflict were caused by FARC and National Liberation Army (ELN) guerrillas, with 80% caused by right-wing paramilitaries, and the remaining 8% caused by Colombian security forces.The strength of the FARCEP forces was high; in 2007, the FARC said they were an armed force of 18,000 men and women; in 2010, the Colombian military calculated that FARC forces consisted of about 13,800 members, 50 percent of whom were armed guerrilla combatants; and in 2011 the president of Colombia, Juan Manuel Santos, said that FARCEP forces comprised fewer than 10,000 members. The Colombian Ministry of Defense reported 19,504 deserters, or individually demobilized members, from the FARC between August 2002 and their collective demobilization in 2017, despite potentially severe punishment, including execution, for attempted desertion in the FARC.In 2012, the FARC made 239 attacks on the energy infrastructure; however, they showed signs of fatigue. By 2014, the FARC were not seeking to engage in outright combat with the army, instead concentrating on small-scale ambushes against isolated army units. Meanwhile, from 2008 to 2017, the FARC opted to attack police patrols with home-made mortars, sniper rifles, and explosives, as they were not considered strong enough to engage police units directly. This followed the trend of the 1990s during the strengthening of Colombian government forces.In June 2016, the FARC signed a ceasefire accord with the President of Colombia, Juan Manuel Santos in Havana. This accord was seen as an historic step to ending the war that has gone on for fifty years. On 25 August 2016, the Colombian president, Juan Manuel Santos, announced that four years of negotiation had secured a peace deal with FARC and that a national referendum would take place on 2 October. The referendum failed with 50.24% voting against. On November 24, 2016, the Colombian government and the FARC signed a revised peace deal, which the Colombian Congress approved on 30 November.On 27 June 2017, FARC ceased to be an armed group, disarming itself and handing over its weapons to the United Nations. One month later, FARC announced its reformation as a legal political party, in accordance with the terms of the peace deal. However, about 2,000 to 2,500 FARC dissidents still take on FARC's original doctrine and continue with drug trafficking, though far smaller than the group at its peak.A small faction of FARC leaders announced a return to armed activity on 29 August 2019, stating that the Colombian government did not respect peace agreements, a position Colombian officials disagreed with. The Colombian government responded with offensive strikes, killing FARC members planning to lead rearmament activities.

The war on drugs is a global campaign, led by the U.S. federal government, of drug prohibition, military aid, and military intervention, with the aim of reducing the illegal drug trade in the United States. The initiative includes a set of drug policies that are intended to discourage the production, distribution, and consumption of psychoactive drugs that the participating governments and the UN have made illegal. The term was popularized by the media shortly after a press conference given on June 18, 1971, by President Richard Nixon—the day after publication of a special message from President Nixon to the Congress on Drug Abuse Prevention and Control—during which he declared drug abuse "public enemy number one". That message to the Congress included text about devoting more federal resources to the "prevention of new addicts, and the rehabilitation of those who are addicted" but that part did not receive the same public attention as the term "war on drugs". Two years prior to this, Nixon had formally declared a "war on drugs" that would be directed toward eradication, interdiction, and incarceration. In 2015, the Drug Policy Alliance, which advocates for an end to the War on Drugs, estimated that the United States spends $51 billion annually on these initiatives, and in 2021, after 50 years of the drug war, others have estimated that the US has spent a cumulative $1 trillion on it.On May 13, 2009, Gil Kerlikowske—the Director of the Office of National Drug Control Policy (ONDCP)—signaled that the Obama administration did not plan to significantly alter drug enforcement policy, but also that the administration would not use the term "War on Drugs", because Kerlikowske considers the term to be "counter-productive". ONDCP's view is that "drug addiction is a disease that can be successfully prevented and treated... making drugs more available will make it harder to keep our communities healthy and safe".In June 2011, the Global Commission on Drug Policy released a critical report on the War on Drugs, declaring: "The global war on drugs has failed, with devastating consequences for individuals and societies around the world. Fifty years after the initiation of the UN Single Convention on Narcotic Drugs, and years after President Nixon launched the US government's war on drugs, fundamental reforms in national and global drug control policies are urgently needed." The report was criticized by organizations that oppose a general legalization of drugs.
