to those who believe the US doesn't sponsor terrorism, I suggest reading a history of South America before coming to that conclusion, and taking special note of the School of the Americas of Fort Benning, Georgia.
"Among the SOA's nearly 60,000 graduates are notorious dictators Manuel Noriega and Omar Torrijos of Panama, Leopoldo Galtieri and Roberto Viola of Argentina, Juan Velasco Alvarado of Peru, Guillermo Rodriguez of Ecuador, and Hugo Banzer Suarez of Bolivia. Lower-level SOA graduates have participated in human rights abuses that include the assassination of Archbishop Oscar Romero and the El Mozote Massacre of 900 civilians."
