Trump’s Iran – President Donald Trump is pitching a new Iran memorandum of understanding at the G7 summit, presenting it as a fresh push to halt nuclear weapon development while easing sanctions and reopening the Strait of Hormuz. The 14-point MOU signed with Iranian Preside
When President Donald Trump walked into the G7 summit with Iran back in the center of the U.S. agenda, he did more than call for another breakthrough. He tied the deal he just signed to what comes next: sanctions relief that could unstick financial transactions. and the reopening of shipping lanes that have been disrupted long enough to push global fuel prices higher.
Trump says the memorandum of understanding he reached with Iran shows progress—pointing to potential sanctions relief and the reopening of shipping routes.
The deal Trump struck with Iranian President Masoud Pezeshkian was signed as a preliminary agreement intended to end fighting between the two countries. The MOU was signed on June 17. almost four months after the United States and Israel first launched joint strikes on Iran to eliminate its nuclear capabilities.
The memorandum states that Iran will refrain from procuring or developing nuclear weapons in exchange for sanctions relief and a $300 billion reconstruction plan. Both sides also agree to reopen the Strait of Hormuz.
The choice of words and the structure of the agreement matter because the U.S. is not encountering Iran over nuclear goals for the first time. Trump’s MOU is the United States’ second attempt this century to prevent Iran from developing a nuclear weapon.
In 2015, then-President Barack Obama negotiated the Joint Comprehensive Plan of Action, known as the JCPOA. That agreement was signed by Iran, the United States, China, France, Germany, Russia and the United Kingdom.
The JCPOA imposed limits on Iran’s nuclear program to prevent it from developing nuclear weapons. In exchange, Iran received phased relief from international economic sanctions.
Trump withdrew from the JCPOA in 2018 during his first term, and the United States began reimposing “maximum pressure” sanctions targeting Iran’s critical energy, petrochemical and financial sectors.
So what actually changes under Trump’s 14-point MOU, compared with Obama’s completed JCPOA?
Sanctions relief and reconstruction funding
Trump’s MOU commits the United States to provide sanctions relief and $300 billion for reconstruction and economic development of Iran with regional partners.
It also commits to terminating all types of sanctions, including sanctions on Iran’s oil and petrochemical exports as well as on U.N. Security Council resolutions.
The memorandum adds that the United States will grant any required licenses, waivers and permissions needed for financial transactions related to the fund. It says the mechanism for implementing the plan will be part of the final deal, to be reached within 60 days.
Obama’s JCPOA did not include a reconstruction fund. Instead, it included sanctions relief and transferred $1.7 billion in cash to settle a decades-old arbitration claim between the United States and Iran.
Strait of Hormuz
The MOU also deals with shipping and energy risk in a direct way. Under the agreement, Iran has agreed to reopen the Strait of Hormuz.
The Strait carried about 20% of the world’s oil supply before the war. The country’s blockade throttled traffic through the channel, driving up fuel prices and threatening the global economy.
The MOU says the United States, which erected its own retaliatory naval blockade, agrees to completely remove it within 30 days, along with “any disturbances or impediments against the Islamic Republic of Iran.” Iran, in turn, agrees to bring vessel traffic to levels before the war.
The Strait of Hormuz was not part of the 2015 agreement because it was not closed at the time.
Nuclear weapons restrictions and uranium enrichment
Obama’s 2015 JCPOA included explicit language that “under no circumstances will Iran ever seek, develop or acquire any nuclear weapons.” It also required Iran to open its facilities to extensive international inspections in exchange for sanctions relief and unfreezing of its foreign assets.
The JCPOA did not shut down Iran’s nuclear program entirely. It allowed Iran to keep a small amount of monitored low-enriched uranium while constraining and restricting Iran’s ability to obtain a nuclear weapon.
It required Iran to keep its uranium enrichment levels at 3.67%, significantly below the 90% enrichment level needed to create a bomb.
The 2015 framework also included “sunset clauses,” key dates when limits on Iran’s capabilities would expire, allowing Iran to resume or increase production.
Trump’s MOU, by contrast, says Iran “shall not procure or develop nuclear weapons.” It does not include details about whether or when Iran will be allowed to enrich uranium.
The Trump administration is instead aiming for permanent restrictions.
Taken together, the differences are mostly about what the two sides trade—and what each deal tries to lock down. Under the MOU. the exchange is not just sanctions relief; it is also tied to a $300 billion reconstruction and economic development plan. plus the reopening of the Strait of Hormuz. with timelines laid out for removing the U.S. naval blockade within 30 days and for completing negotiations toward a final deal within 60 days.
Under the JCPOA, sanctions relief came with detailed limits on enrichment levels—anchored to 3.67%—and with extensive international inspections, a permitted but monitored nuclear footprint, and sunset clauses that would eventually relax certain constraints.
For readers watching the deal cycle again—after Trump’s withdrawal in 2018 and the return of “maximum pressure” sanctions—the question is no longer whether the U.S. is seeking to prevent a nuclear weapon. It’s whether the next structure of tradeoffs delivers lasting limits without repeating the fragility of earlier terms.
At this stage. Trump’s preliminary memorandum has committed to broad sanctions termination. reconstruction funding. and shipping-route changes. while leaving key nuclear and enrichment details for the final deal. Obama’s completed agreement. signed in 2015. had those nuclear guardrails spelled out from the start. down to specific enrichment levels and inspection access.
And while Trump is presenting his MOU as a path forward at the G7, the core proof will hinge on what gets finalized—within 60 days—and whether the restrictions on Iran’s nuclear capability are as durable as the framework suggests.
