President James Monroe proclaimed the Monroe Doctrine in 1823. What is the main point of the doctrine?

A. The U.S. pledged to avoid all involvement in European affairs in return for favorable European trade.
B. The U.S., along with France's military and economic help, has determined to conquer and rule the new I dependent nations of the Western Hemisphere.
C. Only the U.S., Canada, and Mexico should have influence in the Western Hemisphere.
D. European oppression upon the newly independent nations of the Western Hemisphere will be treated as oppression upon the U.S. itself.
Is the answer A?

No.

Why did you guess at this answer?

I read in a book words that sounded like that would be the answer. Is it D?

Yes, it's D. Stop guessing and do your homework!

At first I thought the answer might be C, but the western hemisphere would also include south america. Trade is not mentioned in the doctrine, and France is not either. So I'm guessing that yes the answer is D.

Yes, the main point of the Monroe Doctrine is similar to answer choice A. The correct answer is D. The Monroe Doctrine stated that any further colonization or intervention by European powers in the Americas would be viewed as acts of aggression towards the United States. It asserted that the newly independent nations of the Western Hemisphere should be free from European influence and that the United States would consider any such interference a threat to its own security. While answer choice A does mention trade, it does not capture the essence of the Monroe Doctrine's focus on European oppression and the defense of the newly independent nations.
