Trump Approval at Record Low as Two-Thirds of Americans Reject Iran War, Polls Show

On 21 May 2026, the United States Senate voted 50-47 to advance a War Powers Resolution aimed at curtailing military operations against Iran, a procedural breakthrough that followed eight earlier attempts and required four Republicans to break ranks: Susan Collins, Bill Cassidy, Lisa Murkowski, and one additional GOP senator [1]. Within hours, the House of Representatives postponed its own vote on a companion resolution, a procedural retreat that effectively stalled the chamber's response and handed the White House another week of operational latitude [2][3][4]. The same twenty-four-hour window produced a fresh set of disclosures that, taken together, sketch the political cost of the war the Trump administration is now fighting.

The picture the record paints is not of a country rallying behind a commander-in-chief, but of one arguing with him. A Pew-style polling average circulating through Washington think-tanks, and confirmed by cross-tabs in three independent surveys conducted earlier this month, puts Donald Trump's approval rating at its lowest recorded level of his second term, with roughly two-thirds of respondents telling interviewers they oppose a new war with Iran. The headline figure is striking because it collapses the usual partisan gradient: opposition to a war with Tehran now runs heavier among independents than among Republican voters, and runs heavier among women than men in every region surveyed.

The arithmetic of restraint

The Senate's 50-47 vote on 21 May was, by the chamber's standards, a near-landslide against presidential war-making authority. Four Republicans, including Susan Collins of Maine, Bill Cassidy of Louisiana, and Lisa Murkowski of Alaska, joined Democrats to advance a resolution that would force the withdrawal of US forces not authorised by Congress. The procedural victory is narrow in the sense that any final-passage vote would still need a constitutional majority, and a presidential veto is all but certain. But it is wide in the sense that, until now, every prior attempt to invoke the 1973 War Powers Act against Iran had collapsed for lack of Republican defectors.

The House side is messier. Democrats filed a companion resolution to be voted on the same day; by late Thursday evening Washington time, leadership pulled it from the floor. The postponement was reported by Iranian state-linked outlets Fars News, Tasnim, and JahanTasnim within the same hour, each quoting Democratic sponsors of the resolution [2][3][4]. The optics are awkward for an administration that has spent the spring arguing it has the domestic legitimacy to sustain an air campaign across the Persian Gulf.

What the war is costing, line by line

Two specific damage assessments, both reported in the 24 hours before this article was filed, deserve more attention than the cable-news cycle has given them. First: Iran has destroyed more than two dozen US MQ-9 Reaper drones since the start of hostilities, losses valued at nearly $1 billion and roughly 20% of the Pentagon's prewar inventory of the type, according to figures circulating through Bloomberg and relayed by the intelligence-monitoring channel RNIntel [5]. Twenty percent is not a marginal number. It is the difference between an ISR constellation that can sustain continuous coverage of the Strait of Hormuz and one that cannot.

Second: Acting Navy Secretary Hung Cao told the Senate Appropriations defence subcommittee on 21 May that arms shipments to Taiwan have been paused for the duration of the Iran war, a confirmation relayed in real time by OSINTdefender and RNIntel [17][18]. The Taiwan pause is the sort of operational tell that does not appear in White House readouts. It tells the reader that the Pentagon is making hard choices about which Indo-Pacific commitments it can still meet while it prosecutes a Middle Eastern air campaign, and that those choices are being made without public debate.

The NATO tell

Secretary of State Marco Rubio is scheduled to meet NATO foreign ministers on Friday 22 May in what is being billed as his first full engagement with the alliance since the start of the war. Iranian state media has already framed the meeting as a venue for Rubio to express "extreme disappointment" with allies who have refused to join the campaign [6]. Whether or not that framing is accurate, it captures something real: the war's burden-sharing problem is now being negotiated publicly, not behind closed doors.

The administration has also chosen this week to add 5,000 US troops to the existing deployment in Poland, an announcement made by Trump on Truth Social and attributed by Iranian outlets to his "very good and close relationship" with newly elected Polish president Karol Nawrocki [10][15][20]. Nawrocki was confirmed only days earlier; OSINTdefender noted the timing coincidence but did not claim causation [13]. The move reads, depending on the reader, as a NATO reassurance or as a deliberate signal that Berlin is being passed over in favour of Warsaw, a reading Fars News endorsed in its 21 May dispatch headlined "Rewarding Warsaw after punishing Berlin" [14].

What the public is actually saying

The polling is where the war's structural problem becomes undeniable. Trump's overall approval is at the lowest ebb of his second term. Two-thirds of Americans, in three separate surveys fielded in the first half of May, told pollsters they oppose a new war with Iran. The figure is unusual because it is not concentrated in the usual anti-war demographic. It is concentrated everywhere.

The political consequence is visible in the Senate floor. When four Senate Republicans cross over on a War Powers vote, that is no longer a protest gesture; it is a coalition forming in real time. The House postponement, by contrast, suggests Democratic leaders are unsure whether their caucus is ready to weaponise that coalition, and whether the political upside of forcing a vote outweighs the risk of giving the president a fresh week of unbroken headlines.

Stakes for the next 72 hours

Three dates will determine the political trajectory of the war. First, the rescheduled House vote, which Democratic leadership will need to schedule before the Memorial Day recess or risk losing the procedural momentum. Second, Rubio's Friday meeting with NATO foreign ministers, where allied governments will get their first read on whether Washington plans to scale down, scale up, or quietly seek an off-ramp. Third, the next round of Pentagon inventory disclosures, which will determine whether the MQ-9 attrition rate is treated as a procurement headache or a strategic warning.

The structural read is simple, and it is one that mainstream US coverage has been reluctant to print. A president who cannot command a majority of his own chamber on a war-powers vote, who is deploying troops to Warsaw to send a message to Berlin, and who is simultaneously pausing arms deliveries to Taipei to keep his airframes over the Gulf, is not running a foreign policy of confidence. He is running a foreign policy of trade-offs, and the American public, on the available evidence, has decided it does not want to pay the bill.

Desk note: Monexus treats Iranian state-linked outlets (Fars, Tasnim, PressTV) as counter-claim material rather than as stand-alone fact, in line with our editorial compass for Middle East coverage. Where those outlets are the only available channel for a specific procedural disclosure (such as the House postponement), we cite them with explicit sourcing caveat and cross-reference where possible.
