The corollary to President Trump’s willingness to accept Southeast Asia and the former Soviet Union as spheres of influence for China and Russia, respectively, was a more aggressive stance towards what he viewed as an American sphere of influence in Latin America. Not surprisingly, this led to ongoing friction with Mexico and other South American countries. Trump threatened military intervention on several occasions, and actually followed through with his threat on one or two. As a result, American influence is at its lowest level in about a century.
