Any discussion should consider, but not dwell on, the Monroe Doctrine and what led up to it.
The Monroe Doctrine was a policy of the United States introduced on December 2, 1823. It stated that further efforts by European nations to colonize land or interfere with states in North or South America would be viewed as acts of aggression, requiring U.S. interve ...[text shortened]... the protectors of the newly independent countries of the "New World." The rest was predictable.
Sure but its one thing to set up a protectorate and another to orchestrate assassination and mass murder of civilians, either directly or indirectly and how defensible is the Munro doctrine in dealing against non European intervention but ideologies such as Socialism and Marxism which were almost entirely internal movements?
US KILL LISTS AND ASSASSINATION IN LATIN AMERICA
The U.S. Army’s School of Americas (SOA), started in 1946, trained mass murderers and orchestrated coups in Peru, Panama, Argentina, Ecuador, Bolivia, Guatemala, El Salvador, and Mexico. The SOA trained more than 61,000 Latin American officers implicated in widespread slaughter of civilian populations across Latin America. From 1966-1976 the SOA trained hundreds of Latin American officers in Phoenix-derived methods. Between 1989-1991 the SOA issued almost 700 copies of Project X handbooks to at least ten Latin American countries, including Bolivia, Colombia, Peru, Venezuela, Guatemala, and Honduras. In 2001, SOA was renamed Western Hemisphere Institute for Security Cooperation (WHISC), but peace activists know it as School of Assassins. 
The CIA trained assassination groups such as Halcones in Mexico, the Mano Blanca in Guatemala, and the Escuadron de la Muerte in Brazil. In South America, in 1970-79, Operation Condor, the code-name for collection, exchange and storage of intelligence, was established among intelligence services in South America to eradicate Marxist activities. Operation Condor promoted joint operations including assassination against targets in member countries. In Central America, the CIA-supported death toll under the Reagan presidency alone exceeded 150,000. The CIA set up Ansesal and other networks of terror in El Salvador, Guatemala (Ansegat) and pre-Sandinista Nicaragua (Ansenic).
Honduran death squads were active through the 1980s, the most infamous of which was Battalion 3–16, which assassinated hundreds of people, including teachers, politicians, and union leaders. Battalion 316 received substantial CIA support and training, and at least 19 members graduated from the School of the Americas.
In Colombia, about 20,000 people were killed since 1986 and much of U.S. aid for counternarcotics was diverted to what Amnesty International labeled “one of the worst killing fields.” The US State Department also supported the Colombian army in creating a database of subversives, terrorists and drug dealers.
In Bolivia, Amnesty International reported that from 1966-68 between 3,000 and 8,000 people were killed by death squads. The CIA supplied names of U.S. and other foreign missionaries and progressive priests.
In Ecuador, the CIA maintained what was called the lynx list, aka the subversive control watch list of the most important left-wing activists to arrest. In Uruguay. Every CIA station maintained a subversive control watch list of most important left wing activists. From 1970-72 the CIA helped set up the Department of Information and Intelligence (DII), which served as a cover for death squads, and also co-ordinated meetings between Brazilian and Uruguayan death squads.
In Nicaragua, the US provided illegal funds to the Contras, and Marine intelligence helped maintain a list of civilians marked for assassination when Contra forces entered the country.
In Chile, 1970-73, CIA-created unions organized CIA-financed strikes leading to Allende’s overthrow and subsequent suicide. By late 1971 the CIA was involved in the preparation of lists of nearly 20,000 middle-level leaders of people’s organizations, scheduled to be assassinated after the Pinochet coup.
In Haiti, U.S. officials with CIA backgrounds in Phoenix-like program activities coordinated with the Ton-Ton Macoute, “Baby Doc” Duvalier’s private death squad, responsible for killing at least 3,000 people.
For over thirty years the US military and the CIA helped organize, train, and fund death squad activity in El Salvador. From 1980-93, at least 63,000 Salvadoran civilians were killed, mostly by the government directly supported by the U.S. The CIA routinely supplied ANSESAL, the security forces, and the general staff with electronic, photographic, and personal surveillance of suspected dissidents and Salvadorans abroad who were later assassinated by death squads. US militray involvement in El Salvador allowed “the lessons learned in Vietnam to be put into practice … assisting an allied country in counterinsurgency operations.” 
In Guatemala, as early as 1954, the U.S. Ambassador, after the CIA-orchestrated overthrow of the Arbenz government, gave to the new Armas government lists of radical opponents to be assassinated. Years later, throughout Guatemala’s 36-year civil war, Washington continuously to supported the Guatemalan military’s excesses against civilians, which killed 200,000 people.
