3465-445: The arbitration is often presented as a plot by the UK. Pablo Lacoste in his work "La disputa por el Beagle y el papel de los actores no estatales argentinos" (Argentine Civil Society Agencies in the Beagle Dispute) says: Chile kept in mind the Argentine breach of the arbitration agreement.

Following the suspension of U.S. military aid and training in 1979, Argentina became one of the Somoza regime's principal sources of arms alongside Israel, Brazil and South Africa. In addition to providing arms and training to Somoza's National Guard, the Argentine junta also executed

The court awarded navigable waters on

4466-428: The judgement: the procedure, the legal framework, the judges and the matter in dispute had all been defined by both countries. The procedure had four phases: Chile handed over to the Court 14 volumes and 213 maps, and Argentina 12 volumes and 195 maps. During the first fortnight of March 1976, the Court, accompanied by the Registrar and Liaison Officers from both sides, visited the Beagle Channel region, and inspected

4543-416: The left-wing opposition. US journalist Martha Honey documented the exportation of "social control techniques" which the Argentine army had "brutally perfected" in Argentina to Central American countries. Among the counter-insurgency tactics exported to Central America by Argentina within the framework of Operation Charly, were the systemic use of torture , death squads and forced disappearances —

4620-427: The next in turn. Augusto Pinochet foresaw a long and bloody war, a kind of partisan war: Beagle Channel Arbitration On 22 July 1971 Salvador Allende and Alejandro Lanusse , the Presidents of Chile and Argentina , signed an arbitration agreement (the Arbitration Agreement of 1971 ). This agreement related to their dispute over the territorial and maritime boundaries between them, and in particular

4697-465: The north bank of the eastern part of the Channel to Argentina, but otherwise it met all Chilean claims. Although the arbitration concerned only small islands, the direction of the new demarcation of the frontier would under international maritime law give Chile significant rights running into the Atlantic Ocean, and would also significantly reduce the claims of Argentina on the Antarctic continent and its waters. The Argentine rejection led both countries to

Then the great powers could take sides. In this case,

4928-473: The ranks of the Contras swelled as recruitment became more feasible. By the end of 1982, the Contras were conducting attacks deeper inside Nicaragua than before.

5082-579: The resolution of the conflict would depend not on the combatants, but on the countries that supplied the weapons. Unlike the prelude to the 1982 invasion of the Falkland Islands , from the beginning of Operation Soberanía there were no critical misconceptions on Argentina's side about Chile's commitment to defend its territory: the entire Chilean Navy was in the disputed area, an unequivocal fact at Cape Horn. As stated by David R. Mares in "Violent Peace: Militarized Interstate Bargaining in Latin America": These Chilean advantages do not imply that it could have won

5159-420: The target being first only the Picton, Nueva and Lennox islands, then the "little" Evout, Hoorn, Deceit and Barnevelt islands, then both groups of islands.

On 2 May 1977 the judgement

5313-483: The time of the crisis, the Argentine military was substantially larger than that of Chile; in addition, the Chilean regime was more politically isolated and had suffered deteriorating relations with its main suppliers of arms. The Chilean military, however, had the advantage of defending difficult terrain, as well as being a more professional force, while decades of intervention by the Argentine armed forces in day-to-day politics had degraded their professional skills. There

5544-491: The verge of war. On 22 December 1978 Argentina started military action to invade the islands. Only last minute papal mediation prevented the outbreak of armed conflict. The award was a defeat for Argentine foreign policy and initiated an uncoupling from the international community. The arbitration was completely separate from the Falkland Islands issue, a fact that is often obfuscated or publicly denied in Argentina, where

5621-518: The war against Argentina, but that is not the relevant point. To deter their neighbors the Chileans do not have to demonstrate a capability to win. They need, instead, to make a credible case that a military adventure against Chile would not be cheap. In 1978, the Argentine Junta could not be very confident that war would produce a low-cost victory against Chile. Although it had called off the operation,
