The Alianza Anticomunista Argentina (Triple A) was a group of people in Argentina who were against communism, which is a political system where the government controls everything. They believed that communism was bad and posed a threat to their way of life.
However, instead of just talking about their beliefs or trying to change people's minds through peaceful means, they turned to violence. They began targeting groups and individuals they believed were communist or sympathetic to communism. These targets included labor unions, leftist political parties, and even student groups.
The Triple A used methods such as kidnapping, torture, and assassination to try to scare people away from communism. This resulted in many people being hurt or killed, and it caused fear and unrest in Argentina.
The government at the time turned a blind eye to the Triple A's actions, which only made things worse. Eventually, the group was disbanded, but the harm they caused to people and to the country's political climate was already done.
