Foreign policy of the first Trump administration

U.S. foreign policy during the first presidency of Donald Trump was noted for its unpredictability and reneging on prior international commitments, upending diplomatic conventions, embracing political and economic brinkmanship with most adversaries, and stronger relations with traditional allies. Donald Trump's "America First" policy pursued nationalist and unilateralist foreign policy objectives while prioritizing bilateral relations over multinational agreements.
