From Bill Cassidy to Nikki Haley and Mike Pence, Republicans are questioning whether Trump ended the war by offering Iran more than it gave up.

US President Donald Trump’s agreement with Iran has triggered a widening backlash within his own party, with senators, former administration officials and conservative commentators questioning whether Tehran got too much from the deal without making substantial nuclear or missile concessions.

The criticism intensified after Washington released the text of the 14-point interim agreement on Wednesday. The memorandum stops the fighting, provides for the reopening of the Strait of Hormuz and begins a 60-day negotiating period over Iran’s nuclear programme.

It also envisages the lifting of sanctions, the release of billions of dollars in frozen Iranian assets and the development of a $300-billion reconstruction plan for Iran.

Trump has insisted that the United States will not finance the reconstruction fund and said he had not pressured Gulf countries to contribute. But that assurance has done little to calm Republicans who fear that the agreement could strengthen the Iranian leadership after months of costly warfare.

‘Reagan Is Rolling Over In His Grave’

Louisiana Senator Bill Cassidy delivered the sharpest Republican attack, arguing that the deal had failed to curb Iran’s nuclear ambitions and had taught Tehran that closing the Strait of Hormuz could force the United States to make concessions.

“Reagan is rolling over in his grave," Cassidy said, referring to the former president whom Trump admires.

“Iran’s nuclear ambitions were not curbed, and they have learned that threatening the Strait of Hormuz works and will undoubtedly leverage it in the future."

Cassidy also contrasted the situation before and after the conflict.

“Before the war, the strait was open, Iran was being crushed by sanctions, and 13 [US] service members were still alive. Now, 13 Americans are dead, families have paid billions at the pump, sanctions will be lifted, and the bombing has stopped," he said.

“This is the worst foreign policy blunder in decades."

Republicans Question The Reconstruction Plan

Nikki Haley, who served as US ambassador to the United Nations during Trump’s first term, supported the decision to strike Iran’s nuclear and missile facilities but questioned why the United States and its partners would help rebuild the country afterwards.

“Hitting Iran’s nuclear and missile sites was the right move," Haley wrote on X. But she added: “It’s a huge mistake to pay to rebuild the threat we just destroyed."

“This regime chants death to America, murders our troops, and attempts to assassinate Americans on U.S. soil," she said.

“They believe they have an obligation to destroy us. Now, we plan to unlock billions of dollars and lift sanctions, with the promise of even more money."

Texas Senator Ted Cruz also raised concerns about the financial provisions, even as he praised Trump for weakening Iran’s military.

“Is it giving $300 billion to the Iranian ayatollah?" Cruz asked on his podcast. “I hope not. I pray not."

He later told the Daily Wire that Iran could receive significant financial relief before making its first nuclear concession.

“History teaches that giving billions of dollars to theocratic lunatics who want to murder us is a bad idea," Cruz said.

“Under the terms of what’s been released, somewhere between $10 billion and $30 billion will flow to the Ayatollah immediately before they make even a single nuclear concession."

Fox News contributor Marc Thiessen described the reconstruction proposal as “a disaster", comparing it to offering Germany a Marshall Plan “while the Nazis were still in power".

Pence Compares Deal To Obama-Era ‘Appeasement’

Former vice-president Mike Pence also issued a rare public criticism of Trump, arguing that the memorandum resembled the approach the previous Republican administration had rejected in the 2015 Iran nuclear agreement.

Pence said the deal “does smack of the kind of appeasement that our administration rejected in the Obama-Iran nuclear deal".

“I would urge the President to take a step back, continue the blockade and pursue a negotiated settlement that commits Iran to dismantling their nuclear program, dismantling this missile program, ends support for terrorist proxies and opens the strait," he wrote.

“Failing that, we should let our Armed Forces finish the job on our terms."

Republican critics are now asking whether Trump has secured terms strong enough to distinguish his agreement from the framework he abandoned.

Their concerns deepened after Trump told reporters in France that it would be “unfair" to prevent Iran from retaining “some" ballistic missiles.

That position appeared to fall short of the objectives he outlined when announcing combat operations on February 28. Trump then promised to “destroy their missiles and raze their missile industry to the ground", adding: “It will be totally, again, obliterated."

Iran’s Victory Claim Fuels Republican Anger

Statements from Tehran have further strengthened the argument of Trump’s critics.

Iran’s top negotiator, Mohammed Bagher Ghalibaf, told state television that Iran had obtained far more through negotiations than it had expected to achieve militarily.

“Everything we sought to achieve through military action, we obtained several times over through negotiation; it was not even comparable," he said.

The comment reinforced Republican fears that Iran believes its disruption of the Strait of Hormuz and pressure on global energy markets forced Washington to offer sanctions relief and economic assistance.

According to Axios, Secretary of State Marco Rubio and Defence Secretary Pete Hegseth also raised concerns and questions about the memorandum. Rubio has remained notably quiet on the agreement in recent days.

The backlash has spread to conservative media as well. The New York Post described the agreement on its front page as a “LOVEBOMB" for Iran, while Fox News host Mark Levin said there was “much to be concerned about" and called for amendments.

Former Republican representative Marjorie Taylor Greene, once among Trump’s strongest supporters, described the war as “totally unnecessary".

“This, apparently, is what winning looks like," she said sarcastically.

Trump Defends Deal

Trump has attacked critics of the agreement as “stupid and bad people", arguing that continuing the war would have satisfied only a small minority.

He said carrying on the fighting might have “satisfied a group of 10 percent of the people", but would have “been the wrong thing to do".

The White House has defended the memorandum as a performance-based agreement that ends the fighting, reopens the Strait of Hormuz and creates a path towards preventing Iran from acquiring nuclear weapons.

Trump must now convince one faction of his party that ending the war was necessary and another that Iran was not rewarded for prolonging it. Whether he succeeds may depend on what Tehran agrees to during the 60-day nuclear negotiations.
