The United States entered the First World War in 1917. The United States of America and President Woodrow Wilson were shocked by the destruction of such a humanitarian world. The only way to avoid this recurrence is to establish an international committee aimed at preventing war by maintaining world peace. This will be the mission of the League of Nations. Woodrow Wilson was the founder of the League of Nations in his 14 point speech. This is ironic as the United States did not join the League of Nations.
2) Do you agree that the main responsibility of the United States for not participating in the League of Nations is President Wilson and that he is not against you? A: This is his fault for Congress. They decided not to ratify the Treaty of Versailles. They also do not want to send soldiers they may lose to other countries. They do not want power of other worlds to rule over their country. Congress believes joining the League of Nations threatens their independence. Wilson wants to join the League of Nations, but since the Congress does not like the Treaty of Versailles, the United States did not join.
Federation of the International League The International Alliance is an international organization established in 1919 to maintain world peace. If all the countries are member states and there is a dispute between the countries, it can be resolved through negotiation, not by force. The League of Nations is a good idea, but it eventually failed. Not all countries participate in the alliance, and there is no army in the alliance to prevent Ethiopia, Ethiopia, or Japan from infringing China's Manchuria and other military invasions.
The League of Nations can celebrate its success, but the alliance has any reason to review its failure and where it did not work. These failures, in particular in the 1930s, badly exposed the weaknesses of the League of Nations and played a role in the outbreak of the Second World War in 1939. In the 1920s, the failure of the League of Nations was basically small, not threatening world peace. But they marked - if the hero does not have "playing games", the League of Nations can not solve the problem.
One of the main reasons why the League of Nations failed to achieve the harmony objectives of the world is that countries that initially proposed the organization's vision did not participate. American Senator forbade the United States from joining for the reason that he did not want to abandon the sovereignty of the people and many German Americans who occupied the majority of the population at the time were opposed to the United States under the Treaty of Versailles I boycotted the country to. Their role was indignation. Because the United States did not join the international alliance, the alliance lost a lot of trust in the eyes of other countries. In addition, the United States is a reliable country for relatively novelty and obvious flexibility, loss as a mediator is a blow to the effectiveness of negotiations between North Korea and other countries.
