Bipartisan Backlash Mounts Against Trump's Iran Deal as Peace Talks Open in Switzerland

President Donald Trump’s 14-point Memorandum of Understanding with Iran is facing a gauntlet of bipartisan outrage in Washington, just as Vice President JD Vance arrives in Switzerland to open a 60-day window of direct peace negotiations.[1][3]

The provisional agreement aims to formally end the recent U.S.-Iran military conflict, reopen the critical Strait of Hormuz, and establish a framework for addressing Tehran’s nuclear program.[3][4]

But the ink on the deal is barely dry, and its terms are already under severe strain. Over the weekend, Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy announced it had completely closed the Strait of Hormuz to maritime traffic.[8]

The IRGC cited ongoing Israeli military strikes against Hezbollah in southern Lebanon—which Iran considers a breach of the ceasefire’s spirit—as the catalyst for the blockade, warning all international vessels to stay away from the strategic chokepoint.[8]

The reality on the water remains heavily contested. While Iranian state media broadcast the closure, U.S. Central Command and Vice President Vance insisted the waterway remains open. Vance claimed that 12.5 million barrels of oil successfully passed through in a single night, pointing to the traffic as proof the ceasefire is holding.[4][6]

President Trump responded to the IRGC’s threats with characteristic bluntness, taking to Truth Social to warn that if Iran does not rein in its proxies in Lebanon, the U.S. will "hit Iran very hard again, just like we did last week, only harder."[1][3]

In a subsequent phone interview, Trump threatened to physically take over the Strait if Tehran interfered with shipping. He also floated the unprecedented idea of the U.S. imposing maritime tolls on the waterway if a final deal collapses, framing the fees as reimbursement for America acting as the Middle East's "Guardian Angel."[3]

Back in Washington, the White House is fighting a two-front political war as lawmakers from both parties revolt against the MOU's core concessions. The agreement reportedly involves regional partners establishing a $300 billion reconstruction fund for Iran and offers pathways to sweeping sanctions relief.[5]

Top Senate Republicans, who broadly supported the president’s initial military campaign, have blasted the diplomatic off-ramp. Texas Senator Ted Cruz told reporters that the president was receiving "very, very poor advice," warning that funneling billions to "theocratic lunatics" would inevitably endanger American lives.[5]

Fellow Texas Republican Senator John Cornyn echoed the alarm, arguing that any unfrozen assets or reconstruction funds will be diverted to rebuild Iran’s ballistic missile arsenal and finance regional proxies like Hamas, Hezbollah, and the Houthis.[1][5]

Democrats have been equally scathing, framing the agreement as a capitulation that bypasses congressional oversight. Senator Cory Booker labeled the MOU an "abject surrender," arguing that the administration ignited a disastrous conflict only to grant Iran massive economic benefits to stop it, leaving the U.S. looking like the "biggest loser" on the world stage.[2]

Former Obama-era National Security Adviser Susan Rice called the deal a "jaw-dropping, horrific surrender," criticizing the administration for granting significant upfront concessions before securing a comprehensive, verifiable mechanism to dismantle Iran's nuclear ambitions.[1]

Despite the domestic firestorm, Vance and a U.S. delegation that includes envoys Jared Kushner and Steve Witkoff are pressing ahead in Lake Lucerne, Switzerland. They are meeting with Iranian negotiators, alongside mediators from Qatar and Pakistan, and Rafael Grossi, the head of the International Atomic Energy Agency.[3]

Vance has forcefully defended the framework, emphasizing that not a single U.S. taxpayer penny is going to Iran. He argued that Tehran will only receive international reconstruction funds if it establishes verifiable pathways proving it is not rebuilding its nuclear program.[4][5]

Yet the gap between the two sides remains vast. Iranian President Masoud Pezeshkian declared over the weekend that Tehran will "never back down from the right to enrich uranium," setting the stage for a highly volatile 60-day diplomatic sprint where both the military ceasefire and the global energy markets hang in the balance.[3][7]
