The correct answer is John Quincy Adams.
The Monroe Doctrine was one of the most important policies of the federal government during the 19th century. This doctrine outlined several important issues in terms of international affairs including:
1) The Western Hemisphere was off limits to further European colonization.
2) The United States would not mingle with international affairs that took place in the Eastern Hemisphere.
3) The United States would not interfere with colonies that were already established in the Western Hemisphere by European countries.
4)Any interference by a European country in the Western Hemisphere would be viewed as a hostile act and America would respond accordingly.
