So why was Cuba placed on the terrorism list to begin with

"The United States labeled Cuba a sponsor of terrorism in the early 1980s because of its support for leftist insurgent movements in Latin America. The island also harbored a number of American fugitives, including Joanne D. Chesimard, who is wanted in the killing of a New Jersey state trooper in 1973 and is among the F.B.I.’s most wanted terrorists."
