Why did the Sandinista government face a U.S.-backed insurgency in the 1980s?

The Sandinista government faced a U.S.-backed insurgency in the 1980s primarily because the United States perceived the Sandinista revolution as a potential shift toward communism. Following the 1979 overthrow of the Somoza dictatorship, the Sandinista government established close relations with Cuba and other Soviet-bloc countries, which the administration of U.S. President Ronald Reagan viewed as a threat to U.S. national security.12

In response, the Reagan administration sought to prevent the spread of communism in the region by applying the Reagan Doctrine, which included providing military and economic assistance to opposition forces. In 1981, President Reagan authorized funds to recruit, train, and arm counterrevolutionary insurgents known as the Contras. These insurgents, many of whom were former supporters of the Somoza regime, operated from bases in neighboring Honduras and Costa Rica to engage in military operations against the Sandinista government. While the Contras were never a serious military threat to the Sandinista regime, their attacks on infrastructure and civilian targets caused significant economic damage, which, combined with U.S. trade sanctions, contributed to the destabilization of the Nicaraguan economy.213
