President Trump Faces Iran War Reckoning as Republican Support Wavers and Rising Gas Prices Deepen Cost-of-Living Crisis

As a crucial deadline over U.S. involvement in the Iran conflict draws closer, President Donald Trump is facing intensifying political pressure from Congress, anxious allies, and voters already burdened by rising living costs, while prolonged disruption in the Strait of Hormuz continues to unsettle global energy markets.

Under the U.S. War Powers Resolution, the White House faces a May 1st deadline to either secure Congressional authorization for continued military involvement or scale back operations tied to the two-month-old conflict with Iran, a confrontation that has already shaken global oil supplies and intensified divisions inside the U.S. polity.

The Trump administration has sought to frame its actions as limited and defensive, arguing that U.S. naval operations and support for Israeli strikes were necessary to protect shipping lanes and contain Iran’s regional influence. But Democrats have increasingly questioned whether President Trump has exceeded his constitutional authority by allowing U.S. forces to remain engaged without explicit approval from Congress.

And, even several Republican lawmakers, usually aligned with Trump on foreign policy, have privately and publicly warned that the White House cannot indefinitely rely on executive authority while the military confrontation deepens. The issue has created an unusual split within the president’s own party, with some conservatives backing a harder military line and others warning against another open-ended Middle East war.

For instance, Senator John Curtis of Utah has publicly said that he “will not support ongoing military action beyond a 60-day window without congressional approval.”

Also, Representative Brian Mast, who chairs the House Foreign Affairs Committee, has suggested support could weaken over time, warning that there could be “a different vote count after 60 days.”

At the same time, diplomatic efforts to end the conflict remain stalled.

President Trump reviewed a fresh Iranian proposal on April 27th, but was dissatisfied because it did not directly address Iran’s nuclear programme, according to a U.S. official. Iranian officials had suggested postponing nuclear discussions until after active hostilities ended and disputes over Gulf shipping were resolved, while offering steps that could help reopen the Strait of Hormuz and ease regional tensions.

The Trump administration, however, has rejected that sequencing, insisting that any serious agreement must address Iran’s uranium enrichment and broader nuclear ambitions from the outset.

“He doesn’t love the proposal,” a U.S. official said, describing Trump’s reaction after meeting with top national security advisers.

The disagreement has prolonged a military and economic standoff that began after U.S. and Israeli strikes on Iranian targets in February and escalated further with Washington’s naval blockade targeting Iranian shipping routes.

Iran has condemned U.S. seizures of vessels carrying its oil as “piracy,” while U.S. Secretary of State Marco Rubio has defended the action as a targeted measure against Iranian shipping rather than a general blockade of international trade. Tehran, meanwhile, has tried to use regional diplomacy through Pakistan, Oman and Russia to create space for negotiations.

Foreign Minister Abbas Araqchi visited Moscow this week and welcomed Russian backing for diplomacy after talks with President Vladimir Putin, who has again offered mediation and proposed arrangements involving Iran’s enriched uranium stockpiles.

The conflict’s economic consequences are becoming harder to ignore.

Oil prices rose again on April 28th, as traders reacted to the diplomatic impasse and the near-closure of the Strait of Hormuz, one of the world’s most important energy corridors through which roughly a fifth of global oil and gas supply normally passes.

Brent crude climbed above US$ 109 per barrel, while U.S. West Texas Intermediate approached US$ 98, extending a weeks-long surge that has raised fears of renewed inflation across major economies. Shipping disruptions remain severe, although isolated vessels have managed to pass through the chokepoint, including a UAE-managed LNG tanker.

The White House has argued that sustained pressure is weakening Iran’s economy and forcing Tehran toward compromise. U.S. Treasury Secretary Scott Bessent said this week that Iran’s oil industry was beginning to shut down under the weight of sanctions and maritime restrictions.

But critics in Congress say rising gasoline prices and broader global instability are undercutting that argument, especially as American voters remain sensitive to inflation ahead of the 2026 midterm election.

Democrats have accused Trump of bypassing Congress and risking a broader regional war without a clear strategy, while some Republicans fear that failure to define an endpoint could create a politically costly quagmire.

“This is exactly why Congress exists,” one Republican lawmaker told U.S. media, arguing that sustained military action requires public debate and legislative approval rather than indefinite executive discretion.

The administration has so far signaled little appetite for asking Congress for formal authorization, fearing that a divisive vote could expose bipartisan resistance and weaken Trump’s negotiating position with Tehran.

Instead, officials continue to stress that the President retains authority to protect U.S. interests and maintain freedom of navigation in international waters.

That legal interpretation is unlikely to satisfy critics if the May 1st deadline passes without visible de-escalation.

For President Trump, the coming days are very important as they could shape the domestic political narrative around his second term — whether he is seen as containing a dangerous adversary or dragging Washington into another costly and unpopular Middle East confrontation.

For Iran, the calculation is equally stark: whether limited concessions on shipping and regional stability can persuade Washington to ease military and economic pressure without forcing Tehran into immediate nuclear concessions it sees as politically impossible.

With diplomacy apparently stalled, Congress restless and oil markets reacting by the hour, it remains to be seen whether we are approaching a negotiated end/pause to the current stand-off between the. U.S. and Iran or the opening chapter of a much wider conflict.
