Thus, the main research question is, what are the dimensions and components of the foreign policy of the Biden government? The hypothesis of the research is that by adopting the "America First" policy and adopting a confrontational approach with the international structure and system, Trump challenged the policies of the United States in the international arena, which reduced the power and influence of Washington in The scene of international politics. Meanwhile, Biden's foreign policy perceptions are based on cooperation-seeking with America's allies, democratic coalition building against America's rivals, revival of America's rule-oriented leadership in the world arena, joining international institutions, Atlanticism, priority.Diplomacy has been formed with the participation of all partners and the importance of the satisfaction of the American people in foreign policy decisions.
