US politicians greet Iran deal with deep divisions — and deep doubts

MNTV News Desk

The Islamabad Memorandum of Understanding has landed on Capitol Hill like a political grenade, splitting both parties and exposing raw nerves about the costs and consequences of a war that has lasted more than three months, claimed American lives, and pushed inflation to its highest level in three years.

The response from Republicans — many of whom had cheered the launch of strikes against Iran in late February — ranged from uneasy to openly hostile once details of the agreement began to emerge.

Senator Bill Cassidy of Louisiana called it “the worst foreign policy blunder in decades,” arguing that Iran’s nuclear ambitions had gone unchecked and that Tehran had now learned that threatening the Strait of Hormuz was an effective lever of pressure.

He also noted that Iran would receive new infrastructure investment under the deal.

Senator Thom Tillis of North Carolina, who is not seeking re-election, argued the memorandum fell short given the human and financial costs of the conflict.

The $300 billion reconstruction commitment emerged as the single biggest source of Republican anger, even among some of Trump’s most loyal defenders in the Senate.

Senate Majority Leader John Thune of South Dakota was more measured, acknowledging that the administration had “taken steps” to reduce Iran’s threat potential while saying he hoped that further details would clarify the path forward.

Senator Lindsey Graham said his overriding concern was ensuring Iran had no path to uranium enrichment, adding that he wanted to understand what the deal “actually is” before rendering a full verdict — noting that the way Iran described it was “awful,” while the American version made more sense to him.

Senator Chuck Grassley declined to comment at all until he had read the full text.

Vice President JD Vance, who was the lead negotiator for the U.S. side, sought to frame the agreement as a victory, posting on social media that Iran would never obtain a nuclear weapon and that the Strait of Hormuz would be fully reopened, calling it “peace and prosperity for the American people.”

Some Republican strategists privately acknowledged that the deal put candidates in a difficult position ahead of the midterm elections — neither easy to champion nor safe to oppose, given that it promises an end to hostilities and lower energy prices.

According to NBC, one person close to the administration observed that those who had most enthusiastically supported the war were now likely to turn their criticism toward Vance rather than the president himself.

Democrats were broadly scathing about the terms, though most stopped short of calling for the deal to be rejected.

Senator Chris Murphy of Connecticut described it as “essentially a surrender to Iran on Iran’s terms,” saying Tehran had secured everything it wanted — sanctions relief, implicit control of the Strait, and no nuclear commitments.

Yet he said he would support it nonetheless, because an exit from a war that should never have started was better than continuing it.

Senator Tim Kaine of Virginia said the deal appeared to offer significantly more to Iran in exchange for significantly less than the Obama-era nuclear agreement, known as the JCPOA.

Senator Chris Coons of Delaware said that by virtually every goal Trump had announced when launching the war — from regime change to severing Iran’s support for regional allies to seizing its nuclear material — the administration had come up short.

House Armed Services Committee member Seth Moulton of Massachusetts was among the harshest critics, questioning how reopening a strait that had been freely open before the war could be counted as a victory after more than $100 billion in spending and 14 American deaths.

House Minority Leader Hakeem Jeffries said that while he would need to examine the final terms carefully, the war itself had been “reckless” and “a disaster,” and criticised Trump for withdrawing from the original Iran nuclear deal, arguing the Islamic Republic was now stronger and “Americans less safe as a result.”

Senate Minority Leader Chuck Schumer called on the Trump administration to brief the congressional Gang of Eight on the agreement and to provide wider briefings to the full Congress.

On the question of congressional oversight, the administration’s position remained unsettled. Trump said he intended to send the deal to Congress for review, though the timing was unclear.

Because the agreement is structured as an MOU rather than a formal treaty, Congress has limited direct power to block it, though lawmakers retain leverage through oversight hearings, sanctions legislation, reporting requirements, and funding restrictions.

The Iran Nuclear Agreement Review Act of 2015, passed with overwhelming bipartisan support, gives Congress a formal review process for certain nuclear agreements with Iran — though whether the memorandum triggers that mechanism remains a live legal question.

Trump himself appeared relaxed about the political crossfire, joking at a press conference that he had positioned Vance as the lead negotiator precisely so that he could claim credit if it succeeded and assign blame if it did not.
