The Iran-Contra Affair has had a lasting impact on the United States and on its relationships with Iran and Nicaragua, not to mention the rest of Latin America and the Middle East. The lessons of the affair have been largely forgotten, Congress did not impeach anyone, few were charged with a crime, only two were found guilty, and those same two had their convictions overturned upon appeal (Sorrentino et al., 2021). Being informed of such a brazen moment of corruption and illegal behavior is important for anyone who wants to understand America’s history and politics, particularly its failures. My question in examining this topic is how the Reagan Administration operationalized and justified its involvement in Central America and how that involvement affected Nicaragua and the United States. Given how little was done to restrict the executive from repeating such misadventures in the future, Iran-Contra provides us with a potential example of future abuses of power. The Iran-Contra scandal raised many questions and concerns among the American people; did the CIA support drug running into the US? How corrupt is the administration? What guardrails does Congress have against this happening again, if any? To that final question, there appears a gap in scholarly examinations of the Iran-Contra scandal as to the influence of Congress on moving foreign policy, influencing Reagan to shift. There also appears to be a gap in how the Reagan administration justifies its own positions, at the very least, this appears to be glossed over by scholars.
The Reagan administration knew what they were doing in Nicaragua and Iran was illegal; they knew the public and Congress would be alarmed by their actions, but they did it all anyways. The justification was, in many ways, straightforward. To the Reagan administration, the leftist Sandinistas in Nicaragua—who overthrew a US-aligned dictator in 1979—represented yet another conquest of communism that threatened the rest of the free world (Roberts, 1984). The great thing about this sort of research is that much of their motive was publicized in detail, Reagan wanted the persuade the public to be against the Sandinistas. The administration strongly advocated their position on the rebels—known as Contras—fighting against the Sandinistas, the “White House Digest” released by the Press Secretary in 1984 detailed many human rights abuses and violations to free speech, issues that would resonate with the American public (Roberts, 1984). President Carter had initially tried to bribe the Sandinistas with aid to prevent further alignment with the Soviets and Cubans; Reagan disagreed with this strategy, instead favoring covert operations to oust the Sandinistas (Sorrentino et al., 2021). These covert operations were stopped by the Boland Amendments, which went into effect between 1982 and 1986, prohibiting the executive from engaging in overt of covert operations in Nicaragua (Hicks, 1996, 965). Eventually Congress changes their view on the Sandinistas and favor’s Reagan’s original strategy, lifting restriction and allocating $100,000,000 to the cause—something which Reagan himself advocates for in an address to the nation (Sorrentino et al., 2021; Reagan, 1986). Even though Congress did change its tune on Nicaragua, its previous prohibition was still in place when Oliver North with the National Security Council and CIA had begun work to support the Contras.
Iran is a much more convoluted than Nicaragua. Since the Iranian Revolution in 1979 and the Iran Hostage Crisis, the US led a global effort to embargo and sanction Iran from certain supplies, including weaponry and supporting equipment (Sorrentino et al., 2021). After the hostage crisis was resolved, further hostages were taken by Iranian proxies in Lebanon including a CIA operative; the US also received intelligence reports that there were moderates in the Iranian government who might facilitate the hostages release (Sorrentino et al., 2021). Despite the administration’s own embargo policy, the National Security Council and Oliver North begin communications with Iran, despite the lack of any formal diplomatic relations with the country (Hicks, 1996, 968). To get around the embargo, they do not sell directly to the Iranians, rather, they arranged deals with countries like Israel to sell weapons legally and then those weapons would be turned around and sold to Iran (McCormick & Smith, 1987, 31-32).
Though the administration’s justification for their actions may seem sound, they were in violation of the law. Why did they violate the law? because the Reagan administration were early believers in the unitary executive theory (McPherson, 2025, 101). The unitary executive theory—sometimes referred to as the imperial presidency theory—holds that “the president is the sole authority in the executive branch, for instance in removal of employees, secrecy, implementation of laws, and rule making” (McPherson, 2025, 101). This belief system matches how we see the administration act. Reagan himself claims he did not authorize the covert actions until after Congress approved them, he also denied knowing about the arms sales to Iran, Reagan’s subordinates took the blame instead (McPherson, 2025, 101-102). In the end, Oliver North’s conviction would be overturned by the federal court of appeals, President George H.W. Bush would go on to pardon six senior Reagan officials accused of crimes in the scandal (Sorrentino et al, 2021; McPherson, 2025, 95).
The Iran-Contra Affair demonstrated the extent to which the Reagan administration was willing to circumvent both Congress and the law in pursuit of its foreign policy objectives. By covertly supporting the Contras in Nicaragua and facilitating illegal arms sales to Iran, administration officials operated under a belief that the executive branch possessed broad authority to act independently; justifying these actions were matters of national security and anti-communism. Although the administration publicly framed its actions as necessary to contain communism and secure the release of American hostages, the affair exposed serious weaknesses in congressional oversight and accountability within the executive branch. The limited legal consequences that followed the scandal further reinforced concerns that future administrations could engage in similar abuses of power with little fear of punishment. In this way, Iran-Contra remains significant not only as a Cold War controversy, but also as a warning about the dangers of unchecked executive authority and the fragility of democratic safeguards to U.S. foreign policy.
