Foreign Policy & Defense

Updated July 2026 31 primary sources

U.S. foreign policy spans active wars, ceasefires, and alliance tensions across multiple regions at once.

The Russia-Ukraine war grinds on with no final settlement — U.S.-brokered talks in Geneva and Abu Dhabi have produced prisoner exchanges as Washington cuts direct military aid to roughly $400 million for fiscal 2026 while pushing Kyiv toward territorial concessions in the Donbas in exchange for a security guarantee (Al Jazeera, Reuters).
A major U.S.-Israel-Iran war erupted and then reached a fragile truce — A June 2025 U.S. strike on Iranian nuclear sites ("Operation Midnight Hammer") was followed by a 108-day war beginning February 28, 2026, ending with a June ceasefire and a 14-point U.S.-Iran memorandum of understanding, even as strikes briefly flared again in June (Wikipedia, Republic World, CNN).
Gaza's ceasefire has entered a contested second phase — Built on Trump's 20-point plan, it now involves a "Board of Peace," a technocratic Palestinian administration, and stalled Hamas disarmament talks (CFR, Reuters).
NATO allies are straining under a new spending target as Trump questions U.S. commitment — Allies are working toward the 5%-of-GDP defense-spending goal set at the 2025 Hague summit even as Trump threatens to downgrade U.S. commitment to the alliance (CNBC, Reuters).
The Pentagon, now the Department of War, is operating at record budget levels — Its FY2026 budget hit $961.6 billion, with the administration seeking $1.5 trillion for FY2027 (Breaking Defense).

The Two Positions

Where each side stands

Every point below is sourced to a real organization, official, or news report — click through to read it in full context.

Conservative

America First means peace through decisive strength, not endless wars

Trump-aligned Republicans argue the administration ended the "forever war" era by using overwhelming force in short, targeted operations against Iran while simultaneously pushing to wind down the Ukraine conflict through negotiation rather than open-ended aid (Heritage Foundation, Heritage Foundation).

Europe must finally pay its fair share of NATO defense costs

Trump and Pentagon officials say the 2025 Hague commitment to 5% of GDP was a historic win forced by U.S. pressure, and they continue to publicly shame allies like Spain and the U.K. that lag on the pledge, framing burden-shifting as overdue fairness to American taxpayers (CNBC, POLITICO).

A record defense budget is necessary to deter China and rebuild military readiness

Conservatives backed the $961.6 billion FY2026 defense budget (a 13% increase) and the administration's push toward $1.5 trillion, arguing a decade of underinvestment in shipbuilding, munitions, and the nuclear deterrent left the U.S. unprepared for great-power competition (U.S. Department of War, Heritage Foundation).

Ukraine aid should shift from open-ended grants to a burden-sharing, transactional model

Republicans point to the drop in direct U.S. military assistance to roughly $400 million for FY2026 (down from peak 2024 levels) as proof that Europe, not American taxpayers, should now shoulder the bulk of Ukraine's defense, while the U.S. focuses on brokering a settlement (Facebook/Military Channel USA summary of aid data, NDAA 2026 provisions via Heritage).

Standing with Israel against Iran was a moral and strategic necessity

Administration officials, including Defense Secretary Pete Hegseth, defended the Iran war as removing an existential nuclear threat and argued Democratic critics who invoked the War Powers Resolution were undermining troops and prolonging the conflict (POLITICO, Al Jazeera).

A vocal America First/non-interventionist wing broke with the administration over Iran

Commentators like Tucker Carlson and some libertarian-leaning Republicans argued the Iran war betrayed the "no more foreign wars" promise of Trump's base, calling it a war fought for Israel's interests rather than direct U.S. security — exposing a real split within the conservative coalition (The New York Times, POLITICO).

Progressive

The Iran war was an unconstitutional "war of choice" waged without congressional authorization

Democratic lawmakers, including potential 2028 candidates, condemned the February 2026 strikes as illegal and pushed War Powers Resolution votes to constrain Trump's ability to continue military action against Iran (The New York Times, The Guardian).

Trump's "peace" diplomacy has abandoned Ukraine to Russian territorial demands

Critics argue that tying U.S. security guarantees to Ukraine surrendering the Donbas, and slashing direct military aid to roughly $400 million, rewards Russian aggression and undermines the credibility of any future American security commitment (Reuters, The New York Times opinion).

Trump's erratic treatment of NATO allies is weakening the alliance and America's credibility

Analysts note Trump's threats to leave NATO and public attacks on allies like Spain have coincided with a sharp drop in allied trust in U.S. leadership, even as European defense spending has risen independently of Washington's pressure (Reuters, Gallup, Carnegie Endowment).

The Pentagon budget is bloated, unaudited, and skewed toward contractors instead of human needs

Progressive members of the Congressional Progressive Caucus, including Rep. Ilhan Omar, argue the FY2026 defense appropriations bill enriches contractors and funds "unconstitutional wars" while the Pentagon has failed every audit since 2018 (Congressional Progressive Caucus).

Trump's Gaza plan lacks accountability and enforceable Palestinian self-determination

Human-rights-oriented critics and CFR analysts note the 20-point plan's "Board of Peace" is chaired by Trump himself, includes no binding timeline for an Israeli withdrawal or Palestinian statehood, and has already stalled over Hamas disarmament (CFR, BBC).

Congress and the public deserve transparency on how reconciliation defense funds are spent

Senate Budget Committee Democrats, led by Sen. Jeff Merkley, have demanded the Pentagon explain why $60 billion of the $150 billion defense reconciliation fund remains fully classified, warning it undermines oversight and accountability (Military.com).

Common Ground

Key facts both sides cite

Data and polling that inform the debate — both camps draw on these figures, even when they read them differently.

FY2026 defense budget — The Pentagon's fiscal year 2026 budget totals $961.6 billion (a 13% increase over FY2025), combining $848.3 billion in discretionary funding with $113.3 billion in mandatory reconciliation funds; the administration has since sought a $1.5 trillion topline for FY2027 (U.S. Department of War, Military.com).

U.S. Iran war disapproval — A March 2026 Pew Research Center survey found 59% of Americans said the decision to use military force against Iran was wrong, including 78% of Democrats, 52% support among Republicans, and 62% overall disapproval of Trump's handling of the conflict (Pew Research Center).

NATO defense spending pledge — At the June 2025 Hague summit, NATO allies agreed to raise defense spending to 5% of GDP by 2035 (3.5% core defense plus 1.5% broader security spending); European allies and Canada increased combined defense expenditure by nearly 20% in real terms in 2025 (NATO).

Confidence in Trump's foreign policy handling — A March 2026 Pew Research survey found only 32% of Americans were confident in Trump's decision-making on the Russia-Ukraine war (down from 45% in 2024) and 43% on U.S.-Israel relations, with sharp partisan gaps of 50-plus points on nearly every issue tested (Pew Research Center).
