The diplomatic chessboard surrounding Iran’s nuclear ambitions has once again come alive, with tensions flaring between Tehran and key European powers, while the legacy of a slain American conservative activist adds a poignant twist to the debate over war and peace in the region. On Sunday, September 14, 2025, Iran issued a forceful rebuke to the United Kingdom, Germany, and France—collectively known as the E3—for their recent move to reimpose sanctions that had been lifted under the landmark 2015 nuclear deal. The move, which could restore international sanctions within 30 days if Iran fails to comply with its obligations, has been met with fierce resistance from Tehran.
Iranian Foreign Minister Abbas Araghchi took to the social media platform X to make his country’s position unmistakably clear. "It is not just that the E3 has no legal, political, or moral entitlement to invoke ‘snapback,’ and that even if they did, ‘use or lose it’ doesn't work," Araghchi declared. He doubled down, adding, "It's that the correct expression for the E3's dilemma is ‘use it and lose it.’ Or better yet, ‘use it and lose it all.’" According to reporting by Middle East Eye, Araghchi’s statement underscored Iran’s view that the European powers have forfeited any right to reimpose sanctions now that the United States, under former President Donald Trump, withdrew from the agreement years earlier.
The E3’s announcement in August 2025 that they were triggering the so-called "snapback" mechanism—enshrined in UN Security Council Resolution 2231—sent ripples through international diplomatic circles. The mechanism, designed as a safeguard in the original 2015 accord, allows for the automatic reimposition of sanctions if Iran is found to be violating its commitments. The West, for its part, insists that Iran must return to the negotiating table and allow international inspections of its nuclear facilities, especially in light of recent hostilities and growing concerns over Tehran’s intentions.
The latest standoff comes on the heels of a dramatic—and deadly—summer in the Middle East. On June 13, 2025, Israel launched a surprise attack on Tehran, targeting military, nuclear, and civilian sites, as well as high-ranking military commanders and nuclear scientists. The attack, which caught much of the world off guard, prompted swift and forceful retaliation from Iran in the form of missile and drone strikes. The United States, in a controversial move, bombed three Iranian nuclear sites in what became known as Operation Midnight Hammer. The 12-day conflict, which saw casualties on all sides and raised the specter of a wider regional war, finally came to a halt under a US-sponsored ceasefire that took effect on June 24, 2025.
In the aftermath of these hostilities, Iran suspended its cooperation with the United Nations’ nuclear watchdog, the International Atomic Energy Agency (IAEA), accusing the agency of bias. Iranian officials have argued that the IAEA’s inspections have been weaponized by Western powers to exert undue pressure on Tehran. This suspension of cooperation has only heightened Western anxieties about the true scope and intent of Iran’s nuclear program.
Amid the high-stakes diplomatic wrangling, the story of Charlie Kirk—a prominent American conservative activist whose life and death have become intertwined with the Iran debate—has added a human dimension to the geopolitical drama. Kirk, the founder of the influential youth group Turning Point USA, was assassinated by an unknown assailant on Wednesday, September 10, 2025. The killing shocked the American political landscape and prompted an outpouring of tributes—and questions—about his legacy.
In a revealing interview on the Megyn Kelly Show, US commentator Tucker Carlson shed new light on Kirk’s behind-the-scenes role in shaping the Trump administration’s Iran policy. According to Carlson, Kirk was one of the few people in former President Trump’s inner circle to caution against escalating military conflict with Iran. "He went to the Oval Office and said, ‘Sir, I totally understand and think Iran’s really bad. But a war with Iran is something that could really hurt our country,’" Carlson recounted. He further revealed that Kirk faced "intense" criticism from donors, but remained steadfast in his convictions, insisting that "he was for doing the right and wise and difficult thing."
Kirk’s nuanced stance on Iran was evident throughout his career. In the aftermath of the US’s killing of Iranian General Qassem Soleimani in 2020, Kirk warned against deeper involvement, stating, "Iran is an evil regime … Critical we remain restrained and disciplined against another endless, reckless war in the region. NO WAR with Iran!" Yet, as the conflict escalated in June 2025, Kirk’s position appeared to evolve. During Israel’s 12-day war with Iran, and before the US airstrikes, Kirk told Newsmax on June 20, "They were a great power for a thousand years. Not even the Romans could defeat Persia," highlighting Iran’s resilience and the risks of open war.
However, once President Trump authorized the strikes on Iranian nuclear sites, Kirk voiced public support for the administration’s actions. In a post on X, he wrote, "America stands with President Trump." He elaborated further in a video testimonial, stating, "President Trump has been navigating this quite well in fact, he could potentially declare victory." This shift mirrored the broader divisions within the conservative movement, as some allies questioned the wisdom of military escalation while others rallied behind Trump’s tough stance.
Kirk’s assassination has cast a long shadow over ongoing debates about US policy toward Iran. His willingness to challenge prevailing orthodoxy—even at personal and professional cost—has been cited by supporters as evidence of his integrity and independent thinking. Yet, his ultimate endorsement of military action has also drawn criticism from antiwar activists and some within his own movement, who argue that the US risks being drawn into yet another protracted conflict in the Middle East.
As the world watches to see whether the E3’s snapback gambit will succeed, and whether Iran will return to the negotiating table, the stakes could hardly be higher. With Iran’s nuclear program shrouded in uncertainty, and the memory of a bloody June conflict still fresh, Western leaders are grappling with how best to balance deterrence, diplomacy, and the ever-present risk of escalation.
For its part, Tehran remains defiant. Iranian officials insist that the West’s demands are unreasonable, especially given the US’s unilateral withdrawal from the nuclear deal under President Trump. The Iranian government has repeatedly stated that it will not be bullied into compliance, and that any attempt to reimpose sanctions will be met with resistance—diplomatic or otherwise.
In the end, the fate of the Iran nuclear deal—and the wider peace of the region—may hinge on the willingness of all parties to find common ground. The lessons of recent months, and the words and actions of figures like Charlie Kirk, serve as a stark reminder of the human costs and moral complexities that lie beneath the headlines. As the clock ticks down on the E3’s 30-day ultimatum, the world waits, holding its breath, for the next move in this high-stakes game.
