In 1978 the bellicose Argentine dictatorship abrogated the binding Beagle Channel Arbitration and started the Operation Soberania in order to invade Chile but aborted it a few hours later due to military and political reasons. The conflict was resolved after the Argentine defeat in the Falklands by Papal mediation in the Beagle conflict of Pope John Paul II and in the form of a Treaty of Peace and Friendship of 1984 between Chile and Argentina ("Tratado de Paz y Amistad"), granting the islands to Chile and most of the Exclusive economic zone to Argentina; since then, other border disputes with Chile have been resolved via diplomatic negotiations.
