Throughout the 1970s and ’80s, the Central Intelligence Agency (CIA) was involved in a range of covert activities in South America as a part of Cold War efforts to limit the spread of communism in the region. Although these covert operations were not fully declassified until many years later, rumors of American involvement quickly spread among intelligence and military communities. These operations were an important influence on Clear and Present Danger, which was published amid the scandals.
In the mid-1970s, the CIA provided direct support to Operation Condor, a coordinated campaign of political repression among the right-wing governments of Argentina, Brazil, Bolivia, Chile, Paraguay, and Uruguay. The goal of the operation was surveillance, detention, and operations against political dissidents, especially leftists. The CIA acted as a channel for intelligence coordination and communication among participating regimes. By the late 1970s, details of American involvement had begun to leak into the news.
American attention shifted towards Nicaragua in the late 1970s following the 1979 Sandinista revolution, in which a strongly left-wing government was established. The CIA quickly began secretly organizing and supporting the Contras, a group of anti-communist right-wing rebels staging a guerilla war against the Sandinistas. By 1981, the agency was providing material assistance to the Contras, including training and equipment (“President Reagan Gives CIA the Authority to Establish the Contras.” History, May 2025). When the US Congress restricted aid to the Contras, officials in the Reagan administration secretly facilitated covert arms sales to Iran, diverting the proceeds to continue to support operations. As in Clear and Present Danger, the cover-up was directed by members of the National Security Council.
Clear and Present Danger is the fourth novel in the Jack Ryan series of political and military thrillers written by Tom Clancy. The series began with The Hunt For Red October in 1984, and currently includes 47 novels, most recently The Coldest War (2026). More than half of those novels were co-written or written by other writers after Clancy’s death in 2013. The books are set primarily during the Cold War, and are known for their detailed descriptions of intelligence and military strategy, technology, and geopolitical conflict.
The central character of the series is Jack Ryan, who is introduced as a former Marine and historian who becomes an analyst for the Central Intelligence Agency. Over the course of the series, Ryan rises through the national security hierarchy, eventually serving as National Security Advisor, Vice President, and ultimately President of the United States. The novels follow both his analytical work and his involvement in major international operations. Clear and Present Danger represents a pivotal moment in Ryan’s career, as he transitions from an analyst into Deputy Director (Intelligence) for the CIA.
Another major figure in the series is John Clark, a covert operations specialist who operates in parallel to Jack Ryan. Originally introduced under the name John Kelly, Clark is a former Navy SEAL who transitioned into covert operations following service in the Vietnam War. Clark frequently leads or participates in high-risk missions involving paramilitary operations, providing a contrast to Ryan’s analytical and leadership roles. Although Clark and Ryan both appear in The Cardinal of the Kremlin (1988), they meet for the first time in Clear and Present Danger, establishing a partnership that lasts into Ryan’s presidency.
Apart from the novels, the Jack Ryan universe has also expanded into other media, such as film adaptations of The Hunt for Red October in 1990 and Clear and Present Danger in 1994, amongst others, with the latest instalment, Jack Ryan: Ghost War released in spring 2026. From 2018 to 2023, Amazon Prime Video had a TV series called Tom Clancy’s Jack Ryan, also inspired by Ryan’s adventures in the books.
