From ‘America First’ to Trump Alone: US-Israel Iran War Exposes Deep Global and Domestic Fractures

By Suresh Unnithan & Nanditha Subhadra

As the US-Israel war against Iran stretches into its fourth week, President Donald Trump finds himself increasingly isolated on the world stage and even within his own political base. The conflict, launched with surprise airstrikes on February 28 that targeted Iranian nuclear facilities, missile sites, and reportedly killed Supreme Leader Ali Khamenei, was presented as a bold “America First” move to neutralize a nuclear threat and restore deterrence. Yet critics at home and abroad increasingly view it as an unprovoked escalation fought largely on behalf and for Israel, with the United States bearing the brunt of the costs and risks while traditional allies stand aside.

Trump has repeatedly lashed out at NATO nations for refusing to join what he calls the “US-Israel combine,” warning that the alliance faces a “very bad future” and labeling members “cowards” who have done “absolutely nothing” to help secure the Strait of Hormuz. In recent Truth Social posts, he declared the U.S. “needs nothing from NATO” but urged allies never to forget their reluctance at this critical moment. This public frustration highlights a stark reversal: the self-proclaimed isolationist president who campaigned against endless foreign wars is now fighting one with minimal international support and growing domestic dissent.

NATO’s Firm Refusal and Global Isolation

NATO Secretary General Mark Rutte has offered rhetorical praise for the strikes, describing them as decisive action against Iran’s nuclear and missile programs. However, he and other European leaders have made it clear: this is not a NATO mission. The alliance’s Article 5 collective defense clause applies to attacks on member states, not to offensive operations far beyond Europe’s traditional focus. Major Western powers—including France, Germany, Spain, and Canada—have denied requests for basing rights or direct combat involvement, citing concerns over legality, escalation risks, and the diversion of resources from the ongoing Ukraine conflict.

Eastern European members have voiced sympathy, pointing to Iran’s supply of drones to Russia, but have stopped short of committing troops or naval assets. Turkey has been openly critical. Even as Iran continues missile strikes and disrupts shipping in the Persian Gulf, NATO allies have limited their role to vague “enabling support” or statements pledging “appropriate efforts” to restart navigation—without concrete military contributions. Trump’s mixed messaging, alternating between claiming the war is already “militarily won” and demanding help to police the Strait of Hormuz (which handles about 20% of global oil flows), has left many allies befuddled and unwilling to commit.

Beyond NATO, the broader international community has largely stayed on the sidelines. Russia and China have condemned the strikes, with Moscow warning of reckless brinkmanship near nuclear sites. No wide “coalition of the willing” has formed. Gulf states worry about spillover attacks but offer no active military backing. The result is a lonely campaign: the United States and Israel largely alone against a defiant Iran that continues low-level retaliation and threatens further disruption to energy markets.

Domestic Cracks: Accusations of Fighting Israel’s Battle

The isolation runs even deeper inside the United States. Prominent voices in Congress, including some Republicans, accuse Trump of “dancing to the tunes of Israel” and dragging America into a conflict that primarily serves Israeli Prime Minister Benjamin Netanyahu’s interests rather than core U.S. security needs. Democratic senators have been especially blunt, arguing that the U.S. should not be fighting Israel’s battles while risking broader regional war and economic pain at home.

Even within the GOP, cracks are showing. Some House Republicans emerged frustrated from recent Pentagon briefings, complaining about unclear objectives, potential costs, and the lack of a clear exit strategy. Rep. Nancy Mace publicly stated she would not support ground troops in Iran. Isolationist-leaning figures in the MAGA orbit, along with senators like Rand Paul, have questioned the war’s alignment with “America First” principles and pushed war-powers resolutions to reassert congressional authority—though most Republicans have so far blocked them. Senior GOP lawmakers have voiced irritation over insufficient details on progress and whether additional forces might be needed.

Public opinion reflects this unease. Polls show declining approval for Trump’s handling of the conflict, with independents and swing voters particularly rattled. Surging energy prices—oil topping $100 per barrel and U.S. gasoline approaching or exceeding $4 per gallon in many areas—have amplified economic anxiety. White House aides reportedly warned of midterm risks before the strikes began, but the administration pressed ahead.

Midterm Risks and Trump’s Political Future

The November 2026 midterm elections now cast a long shadow. Republicans hold narrow majorities in Congress, but analysts warn that a prolonged or messy conflict could cost them the House or Senate. Democrats are framing the war as unnecessary foreign entanglement and elite overreach, while highlighting rising costs for American families. Conservative dissent over the war and broader U.S. support for Israel risks fracturing the GOP coalition in key swing districts and states.

If Republicans lose control of one or both chambers, Trump would face a hostile Congress eager to launch oversight investigations into the war’s origins, decision-making process, and lack of prior authorization. Talk of impeachment has already surfaced among Democrats, potentially citing constitutional concerns over unauthorized military action. While conviction in the Senate remains unlikely without significant bipartisan defections, a midterm defeat would severely limit Trump’s legislative agenda, weaken his influence within the party, and damage his legacy heading into future political battles.

Trump continues to project confidence, insisting the strikes have decisively degraded Iran’s capabilities and that victory is at hand. Yet more than three weeks in, with Iranian attacks persisting, the Strait of Hormuz under pressure, and allies refusing to share the burden, the war has exposed deep fractures. The “America First” president who once railed against nation-building and endless Middle East engagements now finds himself waging a high-stakes campaign with little global or even domestic unity.

This isolation may not immediately end Trump’s political career, but it risks cementing a narrative of overreach and miscalculation. History suggests that presidents who pursue lonely wars without broad support often pay a steep price at the ballot box. As gas prices climb and casualty reports potentially mount, the coming months will test whether Trump can extract the U.S. from this conflict before the political damage becomes irreversible—or whether the shift “from ‘America First’ to Trump Alone” will define his second term and beyond.
