United Nations History/League Attacked

Overview
The League lacked its own armed force and so depended on the Great Powers to enforce its resolutions, keep to economic sanctions which the League ordered, or provide an army, when needed, for the League to use. However, they were often reluctant to do so. Benito Mussolini stated that "The League is very well when sparrows shout, but no good at all when eagles fall out."

Article X of the League of Nations (1919)
"The Members of the League undertake to respect and preserve as against external aggression the territorial integrity and existing political independence of all Members of the League. In case of any such aggression or in case of any threat or danger of such aggression the Council shall advise upon the means by which this obligation shall be fulfilled."

Because of these provisions, the United States Senate decided to not ratify the League's Charter.

Anit-Moderni
The League was attacked as being a conspiracy to bring in the One World Government, the Anti-Christ (the supposed "King of the Jews", and set up world wide Judaism. It was also claimed to be Masonic and Nihilistic.

Chaco War
The League failed to prevent the Chaco War between Bolivia and Paraguay in 1932 over the arid Gran Chaco 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.
