Bilateral posture, key relationships, and live diplomatic statements.
Foreign Policy
U.S. foreign policy is still organized around primacy, alliance leadership, and strategic competition with China, but under Donald Trump’s second administration it is more transactional in method and less predictable in coalition management than under recent predecessors The White House, U.S. Department of State, Congressional Research Service. The formal machinery remains conventional: the president sets direction, the National Security Council coordinates, the State Department manages diplomacy, and Congress constrains through appropriations, sanctions law, treaty powers, and oversight The White House, U.S. Department of State, U.S. Senate. In capability terms, the United States remains the system’s central military and financial actor, with military expenditure of $916 billion in 2023, about 3.4% of GDP, far above any other state SIPRI, and a 2024 nominal GDP above $29 trillion World Bank, which gives Washington unusual leverage across security, sanctions, technology controls, and international finance.
Its core interests follow a clear hierarchy. Survival and territorial security center on homeland defense, nuclear deterrence, freedom of navigation, and preventing hostile dominance of Europe, the Indo-Pacific, or the Gulf by a peer or near-peer rival 2022 National Security Strategy, 2022 National Defense Strategy. Regime-security logic is weaker than in most states, but domestic political incentives still shape external behavior through border politics, trade protection, and selective burden-sharing demands Congressional Research Service, U.S. Trade Representative. Economic interests sit just below security: preserving dollar centrality, securing semiconductor and critical-mineral supply chains, protecting maritime trade routes, and limiting technology transfer to China U.S. Department of the Treasury, U.S. Department of Commerce, BIS. Status remains a real driver, expressed through permanent UNSC membership, NATO leadership, and agenda-setting power in the G7, G20, IMF, and World Bank United Nations, NATO, U.S. Department of the Treasury.
Bilateral relationships reflect that pyramid. China is the pacing challenge: Washington combines deterrence in the Indo-Pacific, export controls on advanced chips and manufacturing tools, tighter investment screening, and alliance-building with Japan, Australia, South Korea, and the Philippines U.S. Department of Defense, Bureau of Industry and Security, U.S. Department of State. Russia remains a hard military adversary in Europe, with the United States backing NATO deterrence and Ukraine while using sanctions, export controls, and force posture to raise the cost of Russian revisionism U.S. Department of the Treasury, NATO, U.S. Department of Defense. The U.S.-Israel relationship remains exceptionally close in military and diplomatic terms, while ties with European allies, Canada, Japan, and Australia are structurally strong even when burden-sharing, tariffs, or industrial policy produce friction U.S. Department of State, U.S. Mission to the European Union, Global Affairs Canada. In the Gulf, U.S. behavior mixes deterrence and de-escalation: it maintains force presence to protect shipping and partners while leaving room for diplomacy with Iran when escalation threatens energy flows and regional war U.S. Central Command, U.S. Department of State.
Multilaterally, the United States remains a joiner when institutions amplify its power and a skeptic when they constrain freedom of action. It is embedded in NATO, the G7, the G20, OECD, the UN system, the Bretton Woods institutions, and a dense web of treaty alliances in Europe and Asia NATO, OECD, United Nations. At the UN, Washington often votes with Western partners on Ukraine, nonproliferation, and many human-rights resolutions, but its alignment is far less automatic on Israel-Palestine, the International Criminal Court, and some development or sovereignty questions UN Digital Library, U.S. Mission to the United Nations. The sharpest divergence from its own bloc is Gaza and the broader Israeli-Palestinian file: the United States has repeatedly used its Security Council veto or diplomatic weight to shield Israel where France, the UK, and many other close partners have been more willing to back ceasefire language or stronger criticism UN Security Council, U.S. Mission to the United Nations, UK Mission to the United Nations, France Diplomacy. That break matters more than routine alliance solidarity because it limits U.S. coalition-building in the Global South and weakens its claim to apply international law

More about United States
The United States is still the system’s central military and financial power, but its foreign policy is being pulled by three immediate pressures: strategic competition with China, active military confrontation with Iran, and sharper bargaining with allies over burden-sharing and trade [White House](https://www.whitehouse.gov/), [U.S. Department of State](https://www.state.gov/), [U.S. Department of Defense](https://www.defense.gov/). It is a federal presidential constitutional republic in which the president is both head of state and head of government, with foreign policy concentrated in the White House, the National Security Council, the State Department, and—on the use of force in practice—the Defense Department, while Congress retains major powers over appropriations, sanctions, and treaty approval [The White House](https://www.whitehouse.gov/administration/), [U.S. Senate](https://www.senate.gov/about/powers-procedures/treaties.htm), [U.S. Constitution, Article II](https://constitution.congress.gov/browse/article-2/). The current government is led by President Donald J. Trump, inaugurated on 20 January 2025, with Republican control of the presidency shaping a more transactional external posture centered on deterrence, border control, tariff use, and demands for allied reciprocity [The White House](https://www.whitehouse.gov/administration/president-donald-j-trump/), [Joint Congressional Committee on Inaugural Ceremonies](https://www.inaugural.senate.gov/), [Republican Party Platform](https://www.presidency.ucsb.edu/documents/2024-republican-party-platform). Secretary of State Marco Rubio holds the top diplomatic portfolio in the current cabinet, giving the administration a foreign-policy team that pairs hardline messaging on China and Iran with a preference for direct leader-level bargaining [U.S. Department of State](https://www.state.gov/biographies/marco-rubio/), [The White House](https://www.whitehouse.gov/administration/cabinet/). In institutional terms, the United States remains a treaty ally to much of Europe and the Indo-Pacific through NATO, bilateral alliances with Japan, South Korea, Australia, and the Philippines, and a dense sanctions and export-control architecture that few states can ignore because of the dollar’s role in trade and finance [NATO](https://www.nato.int/cps/en/natohq/topics_52044.htm), [U.S. Department of the Treasury](https://home.treasury.gov/policy-issues/financial-sanctions), [Federal Reserve](https://www.federalreserve.gov/). Economically, the United States remains the world’s largest nominal economy at about $29 trillion in 2024–2025 scale, with output driven primarily by services, consumer spending, advanced manufacturing, technology, finance, and energy, not by goods exports alone [IMF World Economic Outlook Database](https://www.imf.org/en/Publications/WEO/weo-database/2025/April), [Bureau of Economic Analysis](https://www.bea.gov/data/gdp/gross-domestic-product), [World Bank](https://data.worldbank.org/indicator/NY.GDP.MKTP.CD?locations=US). The country is also the world’s largest producer of oil and a top producer of natural gas, which gives Washington unusual resilience during energy shocks and lets it use LNG exports as a geopolitical tool with Europe and Asian partners [U.S. Energy Information Administration](https://www.eia.gov/tools/faqs/faq.php?id=709&t=6), [International Energy Agency](https://www.iea.org/countries/united-states). Its main structural strengths are market size, technological leadership, deep capital markets, and the dollar’s reserve-currency role; its main constraints are high public debt, industrial supply-chain dependence in key sectors, and domestic political polarization that makes long-horizon strategy harder to sustain across administrations [U.S. Department of the Treasury, Fiscal Data](https://fiscaldata.treasury.gov/americas-finance-guide/national-debt/), [Congressional Budget Office](https://www.cbo.gov/topics/budget), [Council on Foreign Relations](https://www.cfr.org/backgrounder/us-china-competition). Three issues define the country’s current trajectory. The first is China: Washington now treats Beijing as its principal long-term competitor and has moved from engagement to selective economic security, using export controls, investment restrictions, industrial subsidies, and alliance coordination to slow Chinese advances in semiconductors and other strategic sectors [The White House](https://www.whitehouse.gov/briefing-room/presidential-actions/2023/08/09/executive-order-on-addressing-united-states-investments-in-certain-national-security-technologies-and-products-in-countries-of-concern/), [U.S. Department of Commerce, BIS](https://www.bis.gov/), [Office of the U.S. Trade Representative](https://ustr.gov/). The second is the Middle East, especially Iran: current cross-Gulf strikes and crisis diplomacy indicate that Washington is trying to re-establish deterrence without sliding into a larger regional war, a pattern that puts military signaling ahead of transformational diplomacy [U.S. Department of Defense](https://www.defense.gov/News/Releases/), [U.S. Central Command](https://www.centcom.mil/MEDIA/PRESS-RELEASES/), [U.S. Department of State](https://www.state.gov/briefings/department-press-briefing/). The third is alliance management: the United States is still indispensable to NATO and Indo-Pacific security, but it is pressing partners more openly on defense spending, industrial policy, and trade terms, which can strengthen burden-sharing while also increasing uncertainty about U.S. guarantees [NATO](https://www.nato.int/cps/en/natohq/topics_67655.htm), [U.S. Department of State](https://www.state.gov/u-s-relations-with-nato/), [Congressional Research Service](https://crsreports.congress.gov/). The key point for delegates is that U.S. policy today is less about universal order-building than about hierarchy: survival and deterrence first, economic-security second, alliance maintenance third, and liberal-norm promotion only when it does not obstruct those priorities [National Security Strategy, White House](https://www.whitehouse.gov/wp-content/uploads/2022/10/Biden-Harris-Administrations-National-Security-Strategy-10.2022.pdf), [Republican Party Platform](https://www.presidency.ucsb.edu/documents/2024-republican-party-platform), [U.S. Department of State](https://www.state.gov/policy-issues/).
