Final answer:
Woodrow Wilson's moral diplomacy differed from the Roosevelt administration's big stick ideology in practice. Wilson's policies were interventionist while Roosevelt's ideology forbade intervention.
Step-by-step explanation:
Woodrow Wilson's moral diplomacy differed from the Roosevelt administration's big stick ideology in practice. While Roosevelt's big stick policy involved the threat of military force to achieve foreign policy goals, Wilson's moral diplomacy aimed to intervene in the international affairs of other nations only when there was a moral imperative to do so. In practice, however, Wilson found it difficult to avoid intervention in Latin America and the Caribbean, and he sent troops to countries like Haiti, the Dominican Republic, and Cuba to protect American interests. Therefore, option 3) Wilson's diplomatic policies were interventionist, while Roosevelt's ideology forbade intervention, is the correct answer.
