It engaged in a systematic campaign of terror amongst the rural Nicaraguan population to disrupt the social reform projects of the Sandinista revolutionary government, destroying health centers, schools, and cooperatives. Murder, rape, and torture occurred on a large scale in contra-dominated areas.[Chomsky, Noam, Turning the Tide. South End Press, 1985].The United States also carried out a campaign of economic sabotage, and disrupted shipping by planting underwater mines in Nicaragua's port of Corinto, an action condemned by the International Court of Justice as illegal. The International Court of Justice, in Nicaragua v. United States in 1984, found, "the United States of America was under an obligation to make reparation to the Republic of Nicaragua for all injury caused to Nicaragua by certain breaches of obligations under customary international law and treaty-law committed by the United States of America". During the war between the contras and the Sandinistas, about 30,000 people were killed.

Dominican Republic population 4.1 million
Bombing began on April 28, 1965. 42,000 American troops invaded the Dominican Republic. Dominicans were seen to be becoming insufficiently anti-Castro and anti-communism.
El Salvador population 4.9 million
In 1985, in El Salvador, a U.S. civilian pilot died on an CIA intelligence mission that ended in a crash on the side of a volcano near San Salvador. In 1983, US Army Sgt. Jay T. Stanley was wounded by gunfire while piloting a helicopter on a mission to establish an airborne communications link with a U.S.-trained rebel battalion in El Salvador. Civil war is of course the ubiquitous strategy of capitalist colonial imperialism. The United States provided huge amounts of military aid to the government of El Salvador during the Carter and Reagan administrations. By May 1983, US officers took over positions in the top levels of the Salvadoran military, were making critical decisions and running the war.[How U.S. Advisers Run The War in El Salvador, The Philadelphia Enquirer, 29 May 1983] The United Nations has estimated approximately 85% of all killings of civilians were committed by the Salvadoran armed forces and death squads.

Libya population 6 million
2011 massive missile strikes and bombing by Americans and NATO nations military acted as an air force for the armed terrorists made in criminal media to appear as ordinary citizens in uprising fighting the Libyan Army and militias. Three months before the assassination of Gaddafi, Gaddafi addressed a wildly pro Gaddafi and pro Socialist Libya demonstration by an near million Libyans with a mile long green flag while British and French planes bombed Tripoli. This was simply not reported in Western media as NATO warplanes finished off the Libyan Army and militias.
After the total destruction of prosperous Libya, murderous infighting between the terrorists themselves and also against pro-Gaddafi tribes has continued on in what is now a waste land.[HUGE PRO GADDAFI RALLY IN TRIPOLI - RAW FOOTAGE, 7/2/2011, www.blacklistednews.com/?news_id=14505
