Final answer:
President Woodrow Wilson had an idealistic and moral diplomacy style that emphasized open diplomacy, free trade, and self-determination of nations. However, his foreign policy decisions often required intervention in other nations' affairs for the sake of American interests and stability.
Step-by-step explanation:
President Woodrow Wilson had an diplomacy style that can be described as idealistic and moral. He believed in promoting peace and stability through open diplomacy, free trade, and self-determination of nations. Wilson's Fourteen Points, which he presented as a postwar peace plan, emphasized these principles and called for an end to secret treaties and negotiations. He also envisioned the creation of the League of Nations as a means to preserve territorial integrity and prevent future conflicts. However, in practice, Wilson's foreign policy decisions often required intervention in other nations' affairs to protect American interests and maintain stability.
