Chile: The Secrets the US Government Continues to Hide

[Judi Lynn]

3. When I saw your post, I immediately remembered seeing an interview on TV with a former CIA

guy, a truly nasty, obnoxious, snotty man, who spoke openly of the fact they put mines in the water in Nicaragua, and I was stunned by the fact he seemed to have absolutely no conscience at all. He was just as cold, and aggressive as anyone might expect.

It was also the first time I'd ever heard they mined a harbor, an evil act which had been done to death already!

I decided to take a quick google check and saw it mentioned in this Wikipedia entry, with a lot more useful information:

CIA activities in Nicaragua

CIA activities in Nicaragua have been ongoing since the 1980s. The increasing influence gained by the Sandinista National Liberation Front, a left-wing and anti-imperialist political party in Nicaragua, led to a sharp decrease in Nicaragua–United States relations, particularly after the Nicaraguan Revolution. In 1981, President Ronald Reagan authorized the Central Intelligence Agency to support the Contras, a right-wing Nicaraguan political group to combat the influence held by the Sandinistas in the Nicaraguan government. Various anti-government rebels in Nicaragua were organized into the Nicaraguan Democratic Force, the first Contra group, at the behest of the CIA. The CIA also supplied the Contras with training and equipment, including materials related to torture and assassination. There have also been allegations that the CIA engaged in drug trafficking in Nicaragua.

. . .

The United States saw the Sandinistas as Communists, and felt the need to stop them. Congress viewed the Reagan Administration's anti-Sandinista policies with extreme skepticism, and were under the impression that the true goal of the CIA operation in Nicaragua was to overthrow the Sandinista government. Congress' efforts resulted in passage of an amendment in late 1982 introduced by Representative Edward P. Boland to the Fiscal Year 1983 Defense Appropriations bill. This is the first of a series of Boland Amendments prohibiting the CIA, principal conduit of covert American support to the Contras, from spending any money "for the purpose of overthrowing the government of Nicaragua".[9] The CIA, however, interpreted the "purpose" stated in this phrase as the purpose of the CIA rather than the purpose of the end user. Thus, the CIA argued that since the purpose of the CIA was not to overthrow the government, that the money and military assistance went to people who had this goal did not matter.[10] The subsequent lack of change in the Nicaragua operation significantly contributed to the eventual further restrictions imposed by Congress in the second version of the Boland amendment.[7]

The majority report stated, "The Central Intelligence Agency was the U.S. Government agency that assisted the contras. In accordance with Presidential decisions, known as findings, and with funds appropriated by Congress, the C.I.A. armed, clothed, fed and supervised the contras. Despite this assistance, the contras failed to win widespread popular support of military victories within Nicaragua."[11]
. . .

The CIA carried out the Nicaraguan operation based on military intelligence indicating the Sandinista government had close ties to the Cuban and Soviet governments, which represented a strategic threat to the U.S.[6] U.S. policy planners also feared that the success of democracy and socialism in Nicaragua would inspire revolutions across the continent, thereby challenging U.S. hegemony and the interests of Western corporations. At this time, the Sandinistas were building their military to a level that was disproportionate for the size of Nicaragua; the U.S. saw this as a Soviet-backed push for power in the region.[6] The CIA gave $50,000 (equivalent to $161,000 in 2022) to the training and arming of the Contras in 1981, which was eventually followed up by millions more once the CIA secured funding for the operation. The CIA executed operations of their own: in 1982, a CIA-trained team blew up two bridges in Nicaragua and mined Corinto harbor, which may have been carried out by members of the U.S. military rather than through the indigenous assets the CIA claimed it used. The mines were an attempt to disrupt the Nicaraguan economy by closing down the main shipping port. Petroleum imports and cotton exports were the main targets.[7] The mines they eventually used were specifically designed to only cause a large noise rather than actually damage ships. The logic behind this is that once a harbor was known to be mined, it would be flagged as such and therefore avoided by most shipping companies. This eventually backfired and became somewhat of a self-fulfilling prophecy for the U.S. as this act actually drove the Sandinista government closer to the Soviet Union because it needed petroleum imports.[7]
