President Donald Trump used a primetime address on Iran to cast his termination of the 2015 nuclear agreement as one of the most consequential acts of his presidency, and to warn that the deal brokered by Barack Obama would have handed Tehran a path to an arsenal of nuclear weapons.
Speaking Wednesday evening, April 1, 2026, Trump called the Joint Comprehensive Plan of Action "a disaster" and said he was "so honored" and "so proud" to have ended it. He described the agreement as fatally flawed from inception, argued that Iran exploited it, and said the Obama administration tried to purchase compliance with planeloads of cash.
The remarks came as part of a broader address on what Trump called Operation Epic Fury, which he described as "necessary for the safety of America and the security of the free world." But the sharpest language was reserved for the deal he inherited, and dismantled, during his first term.
The JCPOA, signed in 2015, exchanged sanctions relief for Iran in return for certain limits and international monitoring of Iran's nuclear program. The Obama administration argued the agreement would push Tehran further from a bomb. Critics saw it differently, and Trump, as Fox News reported, made clear he still views the deal as a strategic gift to an adversary.
Trump listed the JCPOA's termination alongside the January 2020 killing of Gen. Qasem Soleimani as his top actions against Iran. He described Soleimani bluntly:
"I did many things during my two terms in office to stop the quest for nuclear weapons by Iran. First, and perhaps most importantly, I killed Gen. Qasem Soleimani in my first term. He was an evil genius, brilliant person, a horrible human being. The father of the roadside bomb."
He then turned to the nuclear deal itself, accusing Obama of trying to buy Iranian cooperation with enormous cash transfers:
"And then, very importantly, I terminated Barack Hussein Obama's Iran nuclear deal. A disaster. Obama gave them $1.7 billion in cash, green, green cash. Took it out of banks from Virginia, D.C. and Maryland. All the cash they had."
Trump said the cash was meant "to buy their respect and loyalty." Then he paused. "But it didn't work."
The cash question has dogged the Obama legacy since 2016. Critics pointed in part to Wall Street Journal reporting that the U.S. secretly airlifted $400 million in cash to Tehran in January 2016, a transfer that coincided with the release of four American prisoners. The Obama administration maintained that the payment was not part of the nuclear pact itself but the first installment of a separate settlement stemming from a decades-old pre-revolution arms dispute.
Trump has never accepted that distinction, and Wednesday night he folded the payment into a broader indictment of Obama-era financial dealings that he says weakened American leverage. His $1.7 billion figure refers to the total settlement amount, which included the $400 million principal plus $1.3 billion in interest.
The president warned that without his intervention, the consequences would have been catastrophic:
"They laughed at our president and went on with their mission to have a nuclear bomb. His Iran deal would have led to a colossal arsenal of massive nuclear weapons for Iran, and they would have had them years ago, and they would have used them, would have been a different world. There would have been no Middle East and no Israel right now, in my opinion... Had I not terminated that terrible deal, I was so honored to do it. I was so proud to do it. It was so bad right from the beginning."
He added a broader warning about the stakes of inaction:
"The most violent and thuggish regime on Earth would be free to carry out their campaigns of terror, coercion, conquest and mass murder from behind a nuclear shield. I will never let that happen, and neither should any of our past presidents."
Trump's rejection of the JCPOA is not a solo act. Fifty-two Senate Republicans sent the president a letter backing his position that any new Iran agreement must eliminate Iran's ability to enrich uranium entirely, a demand far beyond what the 2015 deal required. The senators called continued enrichment the "fatal flaw" of the Obama-era framework, as the Washington Free Beacon reported.
"During your first term you withdrew the United States from the deeply broken Joint Comprehensive Plan of Action (JCPOA) and imposed maximum pressure on the regime," the GOP senators wrote. They cited Trump's own earlier criticism that the deal "allowed Iran to continue enriching uranium and, over time, reach the brink of a nuclear breakout."
That letter amounts to a congressional firewall against any future administration that might try to revive the old deal's terms. It also signals that the Republican caucus views total dismantlement of Iran's nuclear program, not managed enrichment, as the only acceptable outcome.
The pattern of Obama-era foreign policy decisions drawing renewed scrutiny has only intensified as the current administration pursues a fundamentally different approach to Tehran.
Even as Trump celebrated tearing up the old agreement, his administration has been pursuing a replacement. Trump told reporters the U.S. is "in very serious negotiations with Iran for long-term peace" and is "getting close to maybe doing a deal," the New York Post reported. He framed the choice starkly: "There (are) two steps to doing this, there is a very, very nice step and there is the violent step, but I don't want to do it the second way."
Iranian and U.S. negotiators recently held talks in Oman, but significant gaps remain. Iran has said it will not give up enrichment on its own soil and does not want stockpiles reduced below levels set in the 2015 deal, the very deal Trump walked away from. The sticking points include uranium enrichment levels, sanctions relief, and Iran's stockpile of highly enriched uranium.
Israeli Prime Minister Benjamin Netanyahu has publicly backed Trump's push, telling reporters he spoke with Trump and supports a potential agreement, provided it protects Israel's "vital interests." As the Washington Examiner reported, Netanyahu framed the moment as a chance to leverage military achievements for a diplomatic result.
"President Trump believes that there is a chance to leverage the massive achievements of the IDF and the U.S. military in order to achieve the goals of the war through an agreement, an agreement that protects our vital interests," Netanyahu said.
Trump had called off planned strikes on Iranian power plants after what he described as productive conversations, signaling a preference for pressure-backed diplomacy over open conflict. The administration has been especially concerned about oil-market disruptions and the Strait of Hormuz.
The JCPOA was the centerpiece of Obama's Middle East diplomacy, a bet that engagement and sanctions relief could moderate Iranian behavior. That bet has aged poorly. Iran expanded its enrichment capacity after Trump's withdrawal, and the regime's regional proxies grew bolder. The deal's defenders argue withdrawal caused the acceleration. Its critics, including every Senate Republican who signed last week's letter, say the agreement was always a countdown clock to an Iranian bomb.
What is not in dispute is the political trajectory. Obama's signature foreign policy achievement has become a reliable applause line at Republican events and a policy albatross for Democrats who championed it. The broader scrutiny of Obama-linked institutions and legacy projects reflects a conservative electorate that views the 44th president's record with deep skepticism.
Trump's address also carried a domestic policy subtext. His argument that past administrations wasted taxpayer money on failed diplomatic gambits echoes Republican critiques of other Obama-era programs, including the ongoing battles over Affordable Care Act spending and fraud. The through-line is consistent: the previous administration spent freely, secured little, and left the bill for someone else to pay.
Trump said he is now "correcting" the "mistakes" of former presidents. Whether new negotiations with Tehran produce a tougher agreement or collapse entirely, the political ground has shifted. Fifty-two senators have drawn a red line. Israel's prime minister has endorsed the approach. And the president who tore up the old deal is daring anyone to defend it.
Cash on pallets didn't buy peace. Maybe leverage will.
