Specific analysis:
Historians like to define Wilson as an idealist (or a liberal). Personally, I think he is the most uncompromising realist in the cloak of idealism. His diplomatic thought is to get the United States out of the lonely situation, which can be summarized as follows: the United States will be an envoy of peace, but this envoy will not appear in a place without medals! In other words, what it does will not have no purpose and no return. Wilson can realize that it is not enough to really want to be in the lead. The United States must also let others know what this kind of leadership can bring to others, so the United States began to "maintain world peace." In his "Agenda for World Peace" 14-point plan published after World War I, the establishment of an international alliance can be said to be the core content of the whole plan, because it is an important guarantee for the United States to lead the world and a representative of American interests.
Wilson's diplomacy lies not only in the advanced nature of his thoughts, but also in the magic contained in his words, which is sharp to the outside and incites to the inside. He can always put a gorgeous coat on the ambitious actions of the United States, such as for democracy, for peace, and for the people of all ethnic groups to get rid of suffering as soon as possible. These words are really numerous in his speech. His foreign policy is always full of strong idealism, but it has never been divorced from the closely related interests such as national security and economic prosperity pursued by the United States itself. His diplomatic thoughts profoundly influenced the direction of American diplomacy and eventually became a world leader.
