Which of these best explains the stance of the anti imperialist league
A) Expansion reduced immigration

Answer:
The correct answer here is option D.
Explanation:
The American Anti-imperialist League was created in order to battle the US annexation of the Philippines as they believed such act was in itself undemocratic as it violated the principles of the government that derives its power from the consent of the governed. It also violated the principle of non-intervention that came from the George Washington and his farewell address.
