Final answer:
Wilson's "three core 'isms'" are not a specific set of ideas but can be inferred from his Fourteen Points as liberalism, nationalism, and multilateralism, highlighting his vision for self-determination, free trade, and the creation of an international peacekeeping organization.
Step-by-step explanation:
Woodrow Wilson's Fourteen Points outlined his vision for a stable, long-lasting peace after World War I. Yet, the specific 'three core "isms"' asked about are not explicitly defined in historical texts as a universally recognized term in relation to Wilson. However, examining Wilson's body of work and his Fourteen Points, we can infer that the principles underlying his vision could be broadly categorized into liberalism, nationalism, and multilateralism.
Firstly, liberalism is evident in his advocacy for self-determination, free trade, and open agreements. Wilson's focus on self-determination aligns with liberalist principles of individual liberty and national freedom. Secondly, the nationalism aspect is reflected in his support for national self-determination, suggesting that people should have the right to govern themselves without external interference. Lastly, multilateralism emerges from his fourteenth point, which called for the creation of an international organization—what would later become the League of Nations—to mediate disputes and discourage aggression, illustrating a commitment to cooperative internationalism.
