Where Does U.S. Iran Policy Stand? Trump’s MOU Consideration & What Comes Next

Secure Line · Call Readout · June 1, 2026
Bottom Line Up Front

On FDD Action’s latest Secure Line briefing call, experts Andrea Stricker, Behnam Ben Taleblu, and Richard Goldberg assessed the state of U.S.-Iran negotiations as reports emerged that talks over a 60-day memorandum of understanding (MOU) may be at a standstill. Stricker warned that any MOU that leaves enrichment and reprocessing rights unresolved, or that allows Iran to keep centrifuge infrastructure idle rather than dismantled, risks producing only a temporary setback rather than a durable constraint. Goldberg argued that the entire leverage architecture, including the naval blockade draining $500 million per day from Tehran and the “Economic Fury” sanctions crackdown, will collapse if sanctions relief is provided upfront, before Iran has demonstrated concrete compliance. Ben Taleblu stressed that any agreement must enshrine the military gains of Operations Midnight Hammer and Epic Fury, that the regime should not be rewarded at the bargaining table for nuclear concessions already achieved on the battlefield, and that the Iranian people’s anger at the regime, which was the proximate cause of the entire crisis, remains a critical strategic variable. All three briefers urged Congress to act immediately on the Iran Sanctions Act, which sunsets December 31, and to advance legislation supporting internet freedom in Iran as both a moral and national security priority.

Key Takeaways
  • Enrichment terms are the core issue: Whether Iran is permitted to enrich uranium and reprocess plutonium in the future, and whether any restriction is a permanent ban or a time-limited moratorium, is the central unresolved question. Early U.S. demands for a 20-year restriction have reportedly dropped to between 12 and 15 years, with Iran holding out for five. A moratorium without full dismantlement of centrifuge manufacturing and enrichment infrastructure effectively becomes a much shorter constraint once a less-resolved successor administration takes office.
  • Don’t trade away battlefield gains at the table: Operations Midnight Hammer and Epic Fury have, for the first time in two decades, halted domestic enrichment in Iran through military force. Ben Taleblu argued the administration should not pay diplomatically for what it has already achieved militarily, including by handing Iran a list of monitored sites and making clear that any approach within range triggers a resumption of strikes, deal or no deal.
  • Leverage collapses if sanctions relief comes first: Goldberg warned that relieving the blockade or opening escrow accounts before Iran has verifiably dismantled and delivered enriched uranium inverts the pressure structure. Drawing on the JCPOA experience, he argued that upfront sanctions relief creates an extortion dynamic in which any subsequent enforcement pressure on missiles, terrorism, or the Strait is met with nuclear threats, effectively handcuffing U.S. policy for the duration of any agreement.
  • Underground sites and IAEA access are non-negotiable: Stricker identified two specific sites requiring verified disablement: the deeply buried site near the Natanz complex (possibly more than 100 meters underground and potentially impenetrable to current U.S. bunker-busters) and the new enrichment plant inside the Isfahan tunnel complex, hit with 30 Tomahawk missiles but not yet confirmed destroyed. Any deal must include full IAEA anywhere-anytime access, including at military bases, and a complete Iranian declaration of all past and present nuclear activities.
  • The Iran Sanctions Act sunsets December 31: If Congress fails to renew the Iran Sanctions Act before year’s end, the entire statutory architecture underpinning U.S. sanctions on Iran, including snapback authority, dissolves. The Solidify Iran Sanctions Act has passed the House and needs Senate action. Renewing ISA is essential whether the goal is supporting diplomacy or maintaining a backstop against sanctions erosion.
  • The Iranian people are a strategic variable: The proximate trigger for the entire crisis was the regime’s crackdown against its own people in January. The regime has continued arrests and executions during the ceasefire while pursuing negotiations abroad. Internet freedom legislation, including the FREEDOM Act, the IRAN Act, and the Iran Human Rights, Internet Freedom and Accountability Act, should be treated as a national security priority, not a human rights sideshow.

The MOU and What Must Be In It

As the call opened, moderator Alexandria Paolozzi Moore noted that as of Friday, reports indicated U.S. and Iranian negotiators were on the cusp of agreeing to a 60-day MOU framework, but that by the morning of June 1, talks appeared to have stalled. The briefers were asked to identify their top priorities for any agreement.

Stricker focused on the enrichment and reprocessing question, the two pathways to nuclear weapons fuel, which she said the MOU would likely defer rather than resolve. The reported MOU would require Iran to turn over its enriched uranium stockpile, approximately 9,000 kilograms enriched between two and 60 percent purity, though the post-strike status of those stocks is not fully known. She welcomed the administration’s structure of rewarding only concrete actions, but warned that if the United States has already conceded Iran’s right to enrich in the future, with the restriction declining from the initial 20-year demand to a possible 12 to 15 years against Iran’s preference for five, the agreement risks becoming far shorter in practice. A moratorium without dismantlement of centrifuge manufacturing capabilities, components, and enrichment facilities becomes, in her assessment, closer to a two-and-a-half-year constraint once a successor administration with less resolve takes office and the Iranians seek the first opportunity to restart.

Goldberg said all the right requirements could theoretically be in an MOU: a full declaration of nuclear and ballistic missile activities, a commitment to dismantle underground facilities including the unstruck deeply buried site, surrender of all enriched uranium at all purity levels, cessation of terrorism sponsorship, and destruction of missiles. But he argued that including those requirements means nothing if sanctions relief is front-loaded into the process. The JCPOA precedent he cited was direct: once the United States provided relief, it could not enforce terrorism sanctions, missile sanctions, or anything else without triggering the threat that Iran would resume nuclear activity. His preferred structure would trap Iranian oil revenue in verified escrow accounts, allowing tanker traffic out through the Strait while withholding cash until Iran demonstrated compliance, though he acknowledged Iran might not accept those terms.

Ben Taleblu argued that the starting premise should be that Iran does not get to dictate terms after two rounds of direct military conflict on its soil. He identified three things any deal must lock in: a commitment against rebuilding the nuclear program and the defense industrial base targeted in the strikes; resolution of the nuclear file; and resolution of the Strait of Hormuz. On the nuclear question, his specific counsel was that the administration should not pay at the bargaining table for what it has already achieved on the battlefield. Because there is no domestic enrichment occurring in Iran today, unless one assumes an undisclosed clandestine facility that no deal would address anyway, the administration’s leverage is already realized.

“Don’t pay at the bargaining table for that which you have achieved on the military battlefield. You have stopped, for the first time in two decades, domestic enrichment in Iran with the use of force.”

The Strait of Hormuz and the Sanctions Architecture

Goldberg provided the most detailed treatment of the blockade and sanctions leverage. The naval blockade, combined with Operation Economic Fury’s crackdown on illicit financial networks, is costing Iran an estimated $500 million per day. Imports are not coming in. Exports are not going out. Banks are reportedly drawing down reserves to keep the financial system functioning. Internal regime communications, described internally as “flashing red,” signal acute pressure to reach a deal. Goldberg argued this pressure environment is creating fractures and strategic confusion within the regime that is, on balance, advantageous to the United States.

He described three forms sanctions relief could take: (1) formal waivers or suspension of sanctions allowing legitimate actors to resume transactions; (2) granting Iran access to inaccessible escrow accounts in Qatar and Oman (functionally equivalent to budget support); (3) a “sleight of hand” approach lifting the blockade without formally relieving sanctions, which would in practice allow Iranian oil to flow to Chinese teapot refineries under tacitly-permitted arrangements.

Goldberg’s warning on all three was the same: give up leverage before Iran performs, and you cannot get it back. On restoring Strait traffic, he described Project Freedom, which involved using U.S. naval and air forces to convoy tankers through the Strait, as the right approach, though it lasted only 36 hours before reportedly being suspended when Saudi Arabia withdrew overflight rights. He suggested the administration may be conducting a quieter version, using targeted strikes on Iranian command and control assets when fired upon.

On the Iran Sanctions Act, Goldberg was direct: extending it should be a top congressional priority. The act, currently in the final year of a 10-year extension agreed to under the Obama administration, is the statutory backbone of U.S. sanctions authority against Iran. If it expires, snapback mechanisms dissolve and the architecture collapses. Paolozzi Moore confirmed the Solidify Iran Sanctions Act has passed the House and is pending Senate action through Chairman Scott’s Banking Committee.

“If you relieve sanctions upfront as part of the process, I don’t really understand how you’re getting any of it, because what you would be front-loading is a relief of the pressure that’s driving them to want to do a deal right now.”

Ben Taleblu added that CENTCOM was literally established in response to Iranian threats to Strait traffic during the Iran-Iraq war, meaning the United States has decades of institutional history built around this problem, and that in his view there is “no way out but through” on the Strait, deal or no deal.

Iran’s Internal Situation and the Regime’s Durability

Ben Taleblu addressed the domestic political situation inside Iran. His assessment: the IRGC has always been the ascendant political and military force, and Khamenei’s 37 years of supreme leadership have deliberately produced a system in which hardened military men hold power. The current IRGC consolidation reflects an acceleration of a long-building dynamic, not a new structural change.

The regime’s behavior during the ceasefire is itself a data point: continued arrests, continued executions, government-sponsored rallies designed to suppress street activity, a ballistic missile strike against a base in Kuwait, and continued construction and hardening of the deeply buried nuclear site near Natanz as visible in satellite imagery. The main mood inside Iran, Ben Taleblu said, is not despair but anger, and the population has not forgotten that the proximate trigger for the entire crisis was the regime’s crackdown against its own people in January.

“Deal or no deal, we will not be out of the woods anytime soon when dealing with this country, and the Iranian people haven’t forgotten the trigger for this crisis.”

Underground Sites and Verification

Stricker was asked specifically about the unstruck deeply buried site near the Natanz complex and whether its omission from the Epic Fury strikes changes the verification calculus for any deal. The site is possibly more than 100 meters below a mountain, and analysts worry it could serve as a second Fordow-type enrichment plant at a depth rendering existing U.S. bunker-busters ineffective. The IAEA has never been inside. Satellite imagery shows continued construction and active hardening of entrances and security perimeters since the June strikes.

A second site of concern is the new enrichment plant inside the Isfahan tunnel complex, hit with 30 Tomahawk missiles but whose operational status is unknown; analysts believe it had not yet been substantially outfitted with enrichment infrastructure at the time of the strikes.

Stricker’s bottom line: if an agreement does not require verifiable disablement of these sites, it is not much of an agreement. Any deal must include full IAEA anywhere-anytime access, including at military bases, and a complete Iranian declaration of all nuclear sites, assets, personnel, activities, and past or ongoing military nuclear programs.

“If an agreement doesn’t include a requirement to verifiably disable those sites, then it’s not much of an agreement at all.”

Deep Dives

Goldberg drew a detailed parallel between the current negotiating environment and the JCPOA experience. Under the JCPOA, relief was provided through indefinitely extended waivers in exchange for Iranian nuclear compliance, creating a constraint where any U.S. pressure on terrorism or missiles could be countered by nuclear escalation threats. In practice, there were no meaningful terrorism or missile sanctions during the JCPOA period. The current danger is that a Strait-for-sanctions trade would create the same structure, with Strait closure serving as the new trigger instead of nuclear escalation.

The current danger, he argued, is that a Strait-for-sanctions trade, in which the United States lifts the blockade in exchange for the Strait reopening, creates an analogous structure in which any future enforcement action can be met with a threat to close the Strait again. Once that threat is credible, the United States has effectively transferred its coercive leverage permanently to Tehran. The new extortion racket would be Strait-based rather than nuclear-based, but the underlying dynamic, a regime with a durable trigger it can pull whenever U.S. pressure becomes inconvenient, would be identical.

His preferred alternative, escrowing Iranian oil revenue, allowing physical traffic through the Strait while withholding cash pending demonstrated compliance, is designed specifically to avoid creating that trigger. Iran gets demonstrated U.S. willingness to allow commerce to resume, but does not get the cash until it performs. The question is whether Tehran accepts a structure that denies it the ability to threaten economic retaliation if the United States later applies pressure on non-nuclear issues.

Ben Taleblu pushed back on the framing that the IRGC’s post-conflict political consolidation, including the reported resignation of the Iranian president and the elevation of IRGC veterans to key security positions, represents a new or destabilizing development. The three previous secretaries of the Supreme National Security Council were also IRGC veterans. Iran has had an IRGC-connected president before. What the current moment represents is not a structural change but an acceleration of a coarsening dynamic that Khamenei’s 37-year leadership has deliberately cultivated.

The practical implication for negotiations is that the interlocutors across the table are hardened ideological actors with deep institutional commitments to regime survival and deep suspicion of Western intentions, and that any agreement will be interpreted and implemented through that lens. Ben Taleblu’s counsel was not that this makes a deal impossible, but that it sharpens the requirement for concrete, verifiable, irreversible commitments rather than declaratory assurances. A regime that treats survival as a victory will play to the edge of any agreement’s limits.

Goldberg detailed Operation Economic Fury’s crackdown on illicit financial networks. When the intelligence community is directed to make Iranian illicit networks its top priority, it finds them, including through sanctions on Iraqi oil ministry officials, disruption of shadow banking in the UAE, pressure in Islamabad and Abu Dhabi, interdiction of air traffic used to move money and goods. The $500 million per day estimate reflects a combined maritime, air, overland, and financial cutoff that pure sanctions alone cannot achieve.

Goldberg provided detail on Operation Economic Fury, the parallel economic pressure campaign accompanying the naval blockade. Even prior to the current operations, Iran was exporting an estimated 1.5 million barrels of oil per day illicitly through Chinese teapot refineries and front company networks. India, Japan, South Korea, and legitimate Chinese state enterprises had largely stopped taking Iranian product, but smaller, opaque Chinese refining entities operating two or three degrees removed from sanctionable actors continued to provide Iran a significant revenue stream.

What Economic Fury represents, Goldberg argued, is an intelligence community directive making the illicit financial network the top analytical priority. When the IC is told to find who is enabling Iranian banking, who is taking Iranian oil product, who is insuring Iranian vessels, and who is capitalizing front companies, it finds those networks. The result has been visible in practice: sanctions on Iraqi oil ministry officials, crackdowns on shadow banking networks in the UAE, high-level diplomatic pressure in Islamabad and Abu Dhabi, and interdiction of air traffic being used to move money and goods alongside the maritime blockade. Overland routes through Pakistan have also been disrupted through direct government-to-government engagement. He noted that FDD had recommended expanding the crackdown to civilian airliners being used for illicit purposes, a step that was subsequently taken.

The aggregate effect, he said, is that Iran is effectively cut off on all sides, maritime, air, overland, and financial, in a way that pure sanctions without a blockade could never achieve. The $500 million per day estimate reflects the combined effect of export denial and import denial, not just one side of the ledger.

Ben Taleblu argued the three internet freedom bills (FREEDOM Act, IRAN Act, Iran Human Rights, Internet Freedom and Accountability Act) should be treated as core national security legislation, not peripheral human rights measures. The regime has used 88-day internet blackouts to cover mass repression. Two cyber superpowers, the United States and Israel, face a regime that retains this capability against a pro-American population. Addressing it is a political, strategic, and moral win simultaneously.

Ben Taleblu argued that the 88-day internet shutdown, the world’s longest, that accompanied the regime’s crackdown against its own population should reframe how Congress thinks about internet freedom legislation. The bills he cited, the FREEDOM Act, the IRAN Act, and the Iran Human Rights, Internet Freedom and Accountability Act, are currently treated in Washington as human rights measures at the periphery of the Iran policy debate. He argued they should be treated as core national security legislation.

His reasoning: Iran has one of the most pro-American populations in the Middle East, and the regime uses internet blackouts as a tool of mass repression, covering the killing of tens of thousands under a communications blackout. The United States and Israel are two cyber superpowers. That a regime facing both as adversaries retains the capability to impose total information blackouts on its own population is, in his view, a strategic failure. Addressing it is simultaneously a political win, a strategic win, and a moral win. He noted that even after the internet was nominally restored following the 88-day shutdown, access remains highly tiered and filtered, meaning the regime’s information control capability remains substantially intact.

The broader argument he advanced is that the only durable solution to the Iran problem, the one that actually allows the United States to “downsize the importance of the Middle East in U.S. national security thinking,” as many American voters want, requires removing the arsonist behind many of the region’s fires. Supporting the Iranian people’s ability to organize and communicate is one of the most asymmetric levers available.

Goldberg said no AUMF is needed. The president acted within the War Powers Act for initial operations and declared major hostilities terminated May 1. The blockade’s mission of restoring freedom of navigation is grounded in international law and the inherent right of self-defense. Ben Taleblu went further, calling the War Powers Act likely unconstitutional and arguing its use has consistently tracked partisan rather than strategic or legal lines.

A caller asked whether Congress needs to pass an Authorization for the Use of Military Force (AUMF) to cover ongoing operations. Goldberg’s answer was that he does not see a legal need for one. The president acted within the War Powers Act for the initial military operations and declared major hostilities terminated on May 1. Since then, nine War Powers resolutions have failed in Congress. The blockade, while involving the use of military force, has a distinct stated mission of restoring freedom of navigation through the Strait of Hormuz, and is grounded in international law, treaty obligations to allies, and the inherent right of self-defense.

He noted that he had previously argued for rebranding the ongoing operation as “Operation Epic Passage,” an explicitly defensive convoy operation to restore freedom of navigation, as a cleaner legal and strategic posture than the current zone-defense approach. The president preferred the “Project Freedom” branding and the zone-defense model, which lasted 36 hours. What appears to be happening now, he suggested, is a quieter version of the same thing: targeted strikes on Iranian command-and-control assets when fired upon, which he described as “Project Love Tap.”

Ben Taleblu went further, stating his view that the War Powers Act itself is likely unconstitutional, not as a matter of formal legal analysis, but as a structural argument about the commander-in-chief’s war-making authority. He noted that essentially every congressional invocation of the act has broken along partisan rather than strategic or legal lines, which he argued is evidence that it is being used as a political tool rather than a genuine constitutional constraint.

Stricker’s closing remarks addressed the question of what the administration should be prepared to do if an MOU is not achieved, falls apart, or is determined to be undesirable. Her view: the administration needs to be actively developing and ready to execute options it has so far been unwilling to employ. These include sending in small teams to physically recover high-enriched uranium and other enriched uranium stocks; militarily disabling access to defunct nuclear sites that may hold recoverable assets; and conducting additional strikes. She noted that the Israeli intelligence penetration of the Iranian nuclear program is deep enough that, in the short to medium term, that should help with targeting and assessment.

Her assessment was that President Trump has made a political calculation that a diplomatic agreement is the more achievable path to resolving these issues than military action alone, and that this calculation may be correct. But if that path closes, the contingency planning needs to be in place and the options need to be ready. She also argued that covert efforts to support regime change from within Iran must be part of the long-term strategy, as the only truly durable solution to Iranian nuclear ambitions is a government in Tehran that does not share the current regime’s ideology and incentive structure.

Priorities for Congress

Legislation – Extend the Iran Sanctions Act: The Iran Sanctions Act sunsets December 31, 2026. Congress must pass the Solidify Iran Sanctions Act, which has already been approved by the House, before recess. Failure dissolves the statutory backbone of U.S. sanctions authority and eliminates snapback mechanisms.
Oversight – Define What a Good Deal Looks Like: Congress should articulate clear benchmarks for an acceptable agreement: permanent or near-permanent enrichment ban with full dismantlement; verified disablement of the deeply buried Natanz-adjacent site and the Isfahan tunnel complex; full IAEA anywhere-anytime access including military bases; complete Iranian declaration; and no upfront sanctions or blockade relief before concrete Iranian performance.
Legislation – Internet Freedom for Iran: Advance the FREEDOM Act (H.R. 6469/S. 3360), the IRAN Act (H.R. 7380), and the Iran Human Rights, Internet Freedom and Accountability Act (H.R. 7622/S. 3900) as key national security legislation. The regime’s internet blackout capability has enabled mass repression under communications cover; dismantling it is a strategic priority and a political win.
Oversight – Demand Goodwill Measures Upfront: Push the administration to front-load negotiations with concrete demands: commitment not to shut down the internet, immediate release of all foreign hostages and dual nationals, and release of estimated 21,000 detained after the 12-day war and 55,000 detained after the January crackdown.
Appropriations – Support Contingency Planning: Ensure funding and legal authorities are in place for recovery operations, additional strikes, and covert programs to support regime change from within, not contingent on the outcome of negotiations.

“If the president still wants to dance with the devil, if he wants a victory image, a negotiated resolution, it needs to enshrine the military wins, resolve the nuclear file, and resolve the Strait. But perhaps it’s just good for these things to be communicated to the Iranians, and deal or no deal, you can defang part of their defense industrial base.”
