Identify how the united states intervened in each latin american country.

I found this question and it refers to Chile, Nicaragua and Haiti.
1. Ok, lets start with Nicaragua. The main reason here for the intervention by the United States was to counter the Soviet influence. The US believed that Sandinista leader was a Marxist and therefore the United Intervened and supported the Contras, various rebel groups that opposed the socialist Sandinista government.

2. In Chile, the United States have been heavily involved in number of elections in the late 20th century. After a socialist leader called Salvador Allende was elected president the US forces have allegedly supported the military coup of the Augusto Pinoche who later became a cruel leader of Chile.

3.Haiti themselves had been in the early 20th century actually under the occupation by the United States which lasted from 1915 to 1934. Haiti prior to that have been embroiled in the bitter civil wars and government changed frequently. Adding to that there was a battle for dominance between American and German interests. After the dictatorship of Jean Vilbrun Guillaume Sam who after the anti-American revolt ordered the execution of 167 political prisoners. He was later lynched by an angry mob for actions. The US saw this as a threat to its business interests and intervened. More recently the US has provided relief support for Haiti after the 2010 earthquake.
