His "America First" approach and assertion of U.S. dominance, particularly in the Western Hemisphere, echo historical doctrines like the Monroe Doctrine. These shifts have left global leaders uncertain about future geopolitical realities and the longevity of these changes, with concerns about the pace and disruptive nature of Trump's foreign policy.
