Lacking a clear understanding of American interests and sporting a gigantic ego, President Donald Trump prioritizes personality over principles and objectives in conducting foreign policy. Now, all presidents attempt to develop a rapport with their international counterparts, but they do so in service of a coherent policy that seeks defined national objectives. In Trump's case, the personal relationship is the sole determinant as to his attitude toward a country or group of countries.
North Korean dictator Kim Jong Un shows up to a summit; Trump praises him and ignores his human rights atrocities. Trump hears criticism from Western European leaders, and a trade war breaks out.
