Jelaskan Perang Chaco dari Liga Bangsa dalam bahasa melayu

The League failed to prevent the Chaco War between Bolivia and Paraguay in 1932 over the arid Chaco Boreal region of South America. Although the region was sparsely populated, it gave control of the Paraguay River which would have given one of the two landlocked countries access to the Atlantic Ocean, and there was also speculation, later proved incorrect, that the Chaco would be a rich source of petroleum. Border skirmishes throughout the late 1920s culminated in an all-out war in 1932, when the Bolivian army, following the orders of President Daniel Salamanca Urey, attacked a Paraguayan garrison at Vanguardia. Paraguay appealed to the League of Nations, but the League did not take action when the Pan-American conference offered to mediate instead.

The war was a disaster for both sides, causing 100,000 casualties and bringing both countries to the brink of economic disaster. By the time a ceasefire was negotiated on 12 June 1935, Paraguay had seized control over most of the region. This was recognized in a 1938 truce by which Paraguay was awarded three-quarters of the Chaco Boreal.
