On January 8, 1918, President Woodrow Wilson gave a speech known as the Fourteen Points. In thus he addressed points that he felt would end the war and provide lasting peace throughout the world. A few examples are
Point I. - No secret treaties - Diplomacy shall always take place in the publics eye.
Point II. - Open seas navigation outside of territories.
Point III. - Fair trade for every country and take down all economic barriers that create problems within countries and between countries.
Point XIV. - A "League of Nations" should be formed in order to keep and maintain world peace.
The fourteen points were proposed to do good in the world and designed to make attempts to end the wars. But Wilson's fourteen points created some commotion amongst the allied nations. The League of Nations was a good idea but was abandoned with WWII and out of it formed the UN or present day United Nations.
The most important of the fourteen points would definitely have to be the League of Nations (Point 14). This allowed for a great communication between countries and allowed for better strives at preventing wars between countries. This also set the ground for the modern day UN which is our current organization to try and keep world peace. This is definitely the best option for keeping world peace.
