channel after the invasion of the Falklands, as stated by Brigadier Basilio Lami Dozo, chief of the Argentine Air Force during the Falklands war, in an interview with the Argentine magazine Perfil: L.F. Galtieri said: "[Chile] have to know that what we are doing now, because they will be the next in turn.. In 1982, Argentina still secretly considered Chile an enemy. Chile, perhaps suspecting an Argentine invasion, argued that it was not bound to support Argentina against the UK under the Inter-American Treaty of Reciprocal Assistance because that treaty was defensive in nature, while Argentina was the aggressor in this case and both Chile and Argentina deployed their respective militaries to the border. The common challenge made the chance of military co-operation between the UK and Chile a distinct possibility, and during the war Chile provided the UK with limited, but significant information. One of the reasons given for the absence of the Argentine Navy and higher numbers of professional soldiers during the Falklands War was that these forces had to be kept in reserve in case they were needed against Chile. Treaty of Peace and Friendship of 1984 between Chile and Argentina Tensions between Argentina and Chile did not subside until the democratic government of Raúl Alfonsín took office in Argentina in December 1983. Still isolated diplomatically due to the War, the Alfonsín administration made great efforts to stabilise the border situation. Without the support of the opposition, Alfonsín called for non-binding referendum on 25 November 1984, which produced a result of 82.6% in favour of the second papal proposal. The voting was close only in the territory of Tierra del Fuego, which included the Argentine sector of the disputed Beagle Channel and many military personnel. Even there the vote was narrowly in favour of the treaty. On 29 November 1984, Argentina and Chile signed a protocol of agreement to a treaty in the Vatican City giving the islands to Chile but maritime rights to Argentina. Cultural impact Books Several books have been written about the conflict, the Operation Soberanía and the comparison of the outcome of the Falklands and the Beagle conflict (see Literature). Given that the military critical phase of both conflicts occurred within almost 3 years (December 1978 – April 1982), the conflicts have been analysed as a case for the prospect theory or the role of the mass media in the use of force.
