The Iran-Contra affair was a U.S. political scandal during the 1980s, revealing that senior figures in the Ronald Reagan administration had secretly sold arms to Iran, a country then considered an adversary. The aim was to secure the release of American hostages held in Lebanon by Hezbollah, an Islamist paramilitary group with ties to Iran's Islamic Revolutionary Guard Corps. Simultaneously, the Reagan administration used the proceeds from these arms sales to fund the Contras, an anti-Sandinista rebel group in Nicaragua. This was done despite a Congressional ban on such assistance, outlined in the Boland Amendment.
The affair became public in November 1986 after a plane carrying arms for the Contras was shot down in Nicaragua. Investigations revealed the covert operations, implicating members of the National Security Council (NSC). The scandal raised questions about U.S. foreign policy, executive power, and circumventing Congress. Several officials faced indictments, though some convictions were later overturned due to legal technicalities. The Iran-Contra affair remains a significant moment in Cold War history, highlighting the abuse of presidential powers in foreign affairs and the complexities of U.S. relations with both Iran and Nicaragua.
