United States criticism is met with skepticism by Venezuelan authorities, who claim the weapons are needed to update the basic equipment in the armed forces. In some cases, Venezuelan armaments like the FN FAL have been in service more than 50 years. The government also claims that the U.S. has been the one to initiate arms races and de-stabilize countries by supplying subversive groups in Latin America throughout the past century (referring to the 1954 Guatemalan coup d'état during the Cold War, and the contra affair, among numerous other incidents).Venezuela however has publicly acknowledged its own role in the supplying of thousands of FN Fal rifles, heavy antitank weapons and air support to the Sandinista uprising in Nicaragua during 1978–1979.
