Report which outlines the activity of leftist opposition movements in Nicaragua in their attempt to overthrow the rule of Somoza. The text gives an account of the support which various leftist opposition organizations have received from neighboring countries. According to the information, the following groups have overtly expressed discontent with the ruling regime: The Democratic Union for Liberation, the “Group of Twelve,” the Nicaraguan Democratic Movement, and the Sandinista National Liberation Front (FSLN). Those movements have been supported politically, financially, and in some instances with military aid, by the governments of Venezuela, Mexico, Panama, Costa Rica, and Cuba. The text suggests that two factors have contributed to the escalating tension in Nicaragua – the internal struggle against the regime combined with pressures from outside, coming mainly from the USA, to keep the regime in place.
