Of the innumerable leftist uprisings in Latin America through the years, only two have ever achieved their main goal -- Fidel Castro's Cuban revolution in 1959 and the Sandinistas in Nicaragua in 1979.
After Castro took power almost 40 years ago, Fidel and his Argentine-born lieutenant Ernesto "Che" Guevara promised to create, in their words, "One, ten, a hundred Vietnams in Latin America." Castro and Guevara inspired guerrilla groups all through the region.
However, their dream did not come true. They were met by determined foes in Venezuela in the early 1960s. They met their match against military dictatorships in Argentina, Brazil, Chile and Uruguay in the 1970s.
Some of the Latin American leftist groups were just plain beaten, like the Tupamaros in Uruguay, one of the earliest rebel groups that began in 1960, but were gone twelve years later. A brutal military crackdown in Argentina in the mid-1970s defeated the Montoneros and the ERP. The Ecuadorian government defeated the Afaro Vive Carajo! in the 1980s.
Other rebel groups signed peace deals and even became involved in mainstream politics, such as Colombia's M-19 -- which was a major terrorist force in the 1980s. Others that made peace with their respective governments were the Farabundo Marti rebels in El Salvador and the Guatemalan National Revolutionary Unit, which signed a peace treaty in 1996, after a three decade struggle.
In Peru, the Maoist-inspired Shining Path (SL), which is larger and more violent than the MRTA, is still around and carries out attacks. Since it came into being, Shining Path has carried out almost 1,500 guerrilla attacks and is said to be responsible for the deaths of about 27,000 people. But ever since 1992, when Peruvian authorities captured SL leader Abimael Guzman, Shining Path is not quite the terror organization that it was about ten years ago.
