Overview

The "America First" doctrine has defined Trump's approach to international relations across both terms, fundamentally challenging the post-World War II liberal international order. The philosophy prioritizes bilateral deal-making over multilateral institutions, demands that allies bear greater burdens for their own defense, and views international agreements through the lens of whether they directly benefit American economic and security interests.

First Term (2017–2021)

The first term saw the U.S. withdraw from multiple international agreements: the Trans-Pacific Partnership (2017), the Paris Climate Agreement (2017), and the Iran Nuclear Deal (JCPOA, 2018). The administration also withdrew from the UN Human Rights Council and UNESCO, signaling a broader retreat from multilateral engagement.

On NATO, Trump repeatedly pressured allies to meet the 2% of GDP defense spending target, publicly questioning whether the U.S. would honor Article 5 mutual defense commitments for nations that failed to meet this threshold. While this created diplomatic tensions, NATO allies did increase defense spending during this period.

The Abraham Accords, brokered in 2020, normalized relations between Israel and the United Arab Emirates, Bahrain, Sudan, and Morocco — widely regarded as a significant diplomatic achievement. The administration also pursued direct diplomacy with North Korea, including historic summits with Kim Jong Un, though these did not produce a denuclearization agreement.

Relations with China grew increasingly adversarial beyond trade, encompassing technology restrictions, diplomatic expulsions, and heightened rhetoric over Taiwan, Hong Kong, and the origins of COVID-19.

Second Term (2025–Present)

The second term has been marked by a dramatic shift on the Russia-Ukraine conflict. In March 2025, the administration suspended all U.S. military aid to Ukraine — over $1 billion — following a dispute over peace negotiations and resource concessions. This represented a sharp departure from the bipartisan consensus supporting Ukraine's defense that had prevailed since Russia's 2022 invasion.

The administration has called for European nations to take "primary responsibility" for their own defense, going beyond the first term's spending demands to question the fundamental structure of the transatlantic alliance. Trump has suggested that Europe should fund its own security architecture rather than relying on American military guarantees.

Tariffs of 145% on Chinese goods have further strained U.S.-China relations, while the administration has pursued diplomatic engagement with Russia that critics characterize as accommodating Moscow's interests at the expense of traditional allies.

What Supporters Say

Supporters argue that America First corrects decades of costly foreign entanglements and unfair burden-sharing. They contend that the U.S. has subsidized European defense for too long, and that demanding allies pay their fair share is both reasonable and overdue. Proponents point to the Abraham Accords as proof that unconventional diplomacy can achieve breakthroughs that traditional approaches failed to deliver.

On Ukraine, supporters argue that the conflict is primarily a European security matter and that American taxpayers should not bear the primary cost of a war that does not directly threaten U.S. territory. They advocate for diplomatic resolution over indefinite military support.

What Critics Say

Critics argue that America First undermines the alliance system that has maintained global stability since 1945. They contend that withdrawing from international agreements damages American credibility and creates power vacuums that adversaries like Russia and China fill. The suspension of Ukraine aid, critics argue, rewards Russian aggression and signals to other autocracies that territorial conquest will go unchallenged.

Opponents warn that transactional diplomacy — treating alliances as business deals — erodes the trust and shared values that make collective security effective. They argue that America's global influence depends on its reliability as a partner, and that unpredictability weakens rather than strengthens the nation's strategic position.
