Today's American diplomacy refuses to accept the existence of spheres of influence. Both Hillary Clinton and Blinken have unequivocally stated that spheres of influence belong to the past, although the 50-year long peace that characterized the Cold War period was based on the existence of two spheres of influence, one American and the other Soviet.
The United States has consistently pursued a foreign policy based on spheres of influence since the adoption of the Monroe Doctrine in 1823, completed in 1904 by the Roosevelt Corollary . Thus, the United States has reserved for itself the status of regional policeman in the Western Hemisphere and the right to intervene militarily in the internal affairs of any South or Central American state.
The hypocrisy of American diplomacy and its current representatives is devoid of pragmatism and could lead to serious military conflicts, which can be avoided by simply acknowledging that there are other great nations in the world - such as Russia or China - with major geostrategic interests in their immediate vicinity.
