John McCain was a champion of American leadership on the global stage and an outspoken critic of Donald Trump’s isolationist foreign policy. Following McCain’s death, his political heirs have taken up his mantle and continued his fight against Trumpian isolationism. This includes his daughter, Meghan McCain, who has emerged as an advocate for American internationalism, calling out Trump for his failure to hold Vladimir Putin accountable on the world stage and push for the continuation of US military bases in Eastern Europe. Further, Republican Senators Mitt Romney and Lindsey Graham have both criticized Trump’s foreign policy, accusing him of coddling dictators and alienating staunch allies. McCain’s legacy of American leadership endures through these political voices that are committed to protecting the nation’s reputation as a reliable global partner.
