False. The statement you provided is not an accurate description of the Monroe Doctrine. The Monroe Doctrine, articulated by President James Monroe in 1823, stated that the United States would oppose any further colonization efforts by European powers in the Americas. It asserted that any such attempts would be seen as a threat to the United States' security and interests. The doctrine did not explicitly address pre-emptive action or the United States taking action against clear and present dangers. Its primary focus was on non-interference and the prevention of European colonization in the Western Hemisphere.
