Executive Summary
The U.S. A 60-day memorandum of understanding has been drafted to extend the ceasefire, reopen the Strait of Hormuz, and launch nuclear talks, but Trump has deferred final approval as of May 29, 2026. The deal hinges on three unresolved tensions: Iran's willingness to make verifiable nuclear concessions, Trump's demand that regional states normalize ties with Israel, and competing visions for control of the Strait of Hormuz. The window for diplomatic resolution is narrowing, with both sides maintaining military readiness and continuing limited strikes despite the nominal ceasefire.
Key Findings
- The MOU framework exists but lacks final signatures. Negotiators have reached agreement on a 60-day ceasefire extension with provisions to reopen the Strait of Hormuz and begin nuclear negotiations, but Trump has not signed off and Iran has not formally confirmed acceptance. The draft includes commitments from Iran to never pursue nuclear weapons and to negotiate uranium enrichment suspension, though Iran disputes the scope of these commitments.
- Trump's approval hinges on political and strategic conditions beyond the bilateral agreement. Trump has added a requirement that Egypt, Jordan, Pakistan, Qatar, and Saudi Arabia sign the Abraham Accords as a condition of any Iran deal. This expansion of the negotiation scope introduces new veto points and signals Trump's intent to use the Iran conflict as leverage for broader regional realignment.
- Ceasefire violations continue despite nominal agreement. U.S. military strikes on Iranian missile sites and boats occurred on May 25-26, with Iran's IRGC asserting a "legitimate right to respond" to ceasefire breaches. Both sides are maintaining operational readiness and interpreting ambiguous provisions (mine-laying, blockade scope) as justification for continued military action.
- Iran's nuclear concessions remain verbal and unverified. Iranian negotiators have given only verbal commitments on uranium enrichment suspension and stockpile removal. U.S. officials acknowledge uncertainty about Iran's actual willingness to deliver, stating the MOU is designed to "get both sides into the room" to test Iranian sincerity during the 60-day window.
- The Strait of Hormuz remains contested terrain. Iran's IRGC navy is asserting control over the waterway and prohibiting vessels from "hostile countries," contradicting the proposed "unrestricted" transit terms. Trump has stated the U.S. will "watch over" the strait, signaling potential military enforcement of navigation rights.
The Negotiation Stalemate
The draft MOU represents the most significant diplomatic progress since fighting began on February 28, but it is fundamentally a framework for further negotiation rather than a settlement. The 60-day window is designed to test whether Iran will make concrete nuclear concessions in exchange for sanctions relief and asset unfreezing. However, the structure itself reveals the depth of mistrust: the U.S. will only implement sanctions relief "as part of a final agreement that is verifiably implemented," while Iran has demanded immediate asset unfreezing and permanent sanctions removal.
Trump's hesitation reflects genuine uncertainty about Iran's intentions. U.S. officials have stated that if Iran fails to deliver on nuclear issues during the 60-day period, "Trump will have all options on the table, economic and military." This language preserves the option for renewed strikes, making the ceasefire conditional on Iranian performance rather than a genuine pause in hostilities.
The addition of the Abraham Accords requirement introduces a new complication. Trump's demand that regional states normalize ties with Israel is not part of the bilateral U.S.-Iran negotiation but rather a condition imposed on third parties. This approach expands the scope of what Iran must accept and gives regional actors (particularly Saudi Arabia and Pakistan) veto power over the deal's viability.
The Strait Of Hormuz As Leverage
The reopening of the Strait of Hormuz is the most concrete deliverable in the proposed MOU, but it is also the most contested. The draft specifies "unrestricted" navigation with no tolls or harassment, and requires Iran to remove mines within 30 days. However, Iran's IRGC navy is currently asserting that vessels from "hostile countries" are prohibited from transit, directly contradicting the proposed terms.
This discrepancy reflects a deeper strategic calculation: Iran may view continued control of the strait as its primary leverage in post-ceasefire negotiations. By maintaining the ability to disrupt shipping, Iran preserves a coercive tool if negotiations stall. Trump's statement that the U.S. will "watch over" the strait signals willingness to enforce navigation rights militarily, creating a scenario where the ceasefire could collapse over enforcement of this single provision.
Israel'S Role And Regional Escalation
Israel has intensified operations in Lebanon, with the IDF conducting strikes on over 150 sites targeting Hezbollah in recent days. Lebanese health authorities report at least 3,269 killed since late February. The U.S.-Iran negotiations do not include Israel as a formal party, but Israel has privately described the emerging deal as a "bad idea" and is pushing for continued operations against Hezbollah.
Iran has demanded that any final agreement include an end to Israeli operations in Lebanon. This condition is not part of the current MOU but is emerge as a sticking point in the 60-day negotiation window. The divergence between U.S. diplomatic goals (reopening the strait, nuclear talks) and Israeli military objectives (degrading Hezbollah) creates a structural tension that could derail the agreement.
Trump'S Domestic Political Calculus
There is significant political pressure on the White House to resolve the conflict before midterm elections. Trump has stated he does not care about the midterms and is not in a rush, but the timing of the negotiations suggests otherwise. The conflict has disrupted global oil markets and created economic headwinds that could affect voter sentiment.
Trump's wavering between military escalation and diplomacy reflects this tension. In April, he threatened that "a whole civilization will die tonight, never to be brought back again." By late May, he was describing the deal as potentially "brilliant" and a path to regional stability. This oscillation suggests Trump is genuinely uncertain about the optimal strategy and is seeking political cover for whichever path he chooses.
Key Assumptions
| Assumption | Supporting Evidence | Falsifying Evidence | Impact if Wrong |
|---|---|---|---|
| Iran will negotiate in good faith during the 60-day window | U.S. officials cite Iran's economic desperation and verbal commitments on nuclear issues | Iran has disputed the scope of nuclear concessions and released multiple versions of the agreement with discrepancies | If Iran uses the 60 days to stall while rebuilding capabilities, Trump will moderate-to-high confidence resume military operations, escalating the conflict beyond February-May levels |
| The Strait of Hormuz can be reopened without Iranian control mechanisms | The MOU specifies "unrestricted" transit and U.S. enforcement | Iran's IRGC navy is currently asserting control and prohibiting hostile vessels; Iran may demand tolling or passage fees | If Iran maintains de facto control of the strait, the economic benefits of reopening will be limited and the U.S. will face pressure to enforce navigation rights militarily |
| Regional states will accept the Abraham Accords requirement | Trump has framed this as a condition for the deal; some states have already signed | Saudi Arabia and Pakistan have not confirmed willingness to normalize ties with Israel; Egypt and Jordan may face domestic opposition | If key regional states refuse, Trump may abandon the diplomatic track and resume military operations, or accept a narrower bilateral agreement with Iran |
Counterarguments
-
The MOU may be a diplomatic cover for continued military pressure. Critics argue that Trump is using the negotiation framework to justify continued U.S. strikes while maintaining the appearance of pursuing peace. The May 25-26 strikes on Iranian missile sites and boats occurred during active negotiations, suggesting the U.S. is not genuinely committed to a ceasefire. If this interpretation is correct, the 60-day window will be used to degrade Iranian capabilities rather than to negotiate a settlement, and the deal will collapse when Iran recognizes this strategy.
-
Iran's nuclear concessions may be illusory. Iran has given only verbal commitments on uranium enrichment and stockpile removal, and has explicitly denied making commitments on the nuclear issue. U.S. officials acknowledge they "will not know until we get in the room" whether Iran will actually deliver. If Iran uses the 60-day period to extract sanctions relief without making verifiable concessions, the U.S. will have strengthened Iran's economy while failing to constrain its nuclear program, and Trump will face domestic criticism for a weak deal.
-
Israel's refusal to end operations in Lebanon could derail the agreement. The U.S. has not secured Israeli commitment to halt operations against Hezbollah, and Netanyahu has privately criticized the emerging deal. If Israel continues escalating operations in Lebanon during the 60-day window, Iran may withdraw from negotiations or demand additional concessions. This dynamic could force Trump to choose between supporting Israel or pursuing the Iran deal, a choice that could fracture the U.S.-Israel alliance or collapse the agreement.
Indicators To Watch
| Indicator | Current State | Warning Threshold | Time Horizon |
|---|---|---|---|
| Strait of Hormuz commercial shipping volume | ~15 ships/day (May 30); pre-war baseline ~300 ships/day | <50 ships/day sustained after 30 days of MOU implementation | 30-60 days |
| Iranian uranium enrichment activity | Suspended under ceasefire; IAEA access denied since February | Resumption of enrichment at pre-war levels or higher; IAEA reports new stockpile accumulation | 30-60 days |
| U.S. military strikes on Iranian targets | Ongoing despite ceasefire (May 25-26 strikes); claimed as "self-defense" | >2 strikes/week; expansion to new target categories (nuclear facilities, leadership) | 7-14 days |
| Regional state normalization with Israel | 5 signatories to Abraham Accords; Trump demanding 5 additional states | Public commitment from Saudi Arabia or Pakistan to normalize ties | 14-30 days |
| Israeli operations in Lebanon | 150+ strikes in past week; 3,269+ killed since late February | Expansion of ground operations beyond current "Yellow Line"; strikes on Beirut leadership targets | 7-14 days |
Decision Relevance
Scenario A (~45%): Conditional ceasefire extends into 60-day negotiation window with limited progress on nuclear issues. The MOU is signed but Iran makes only cosmetic concessions on uranium enrichment. The Strait of Hormuz remains partially restricted, and regional states decline to sign the Abraham Accords. Trump extends the ceasefire repeatedly but does not achieve a final agreement. Recommended action: Assume continued volatility in global oil markets; maintain hedged energy exposure; do not commit capital to Middle East infrastructure projects pending resolution.
Scenario B (~35%): Negotiations collapse within 30 days; military operations resume. Iran refuses to make verifiable nuclear concessions or continues asserting control over the Strait of Hormuz. Trump resumes strikes on Iranian nuclear and military facilities. The conflict escalates beyond February-May levels, with potential for direct U.S.-Iran naval confrontation in the Gulf. Recommended action: Prepare for oil price spike to $120-150/barrel; accelerate supply-chain diversification away from Middle East; increase insurance costs for shipping through the strait.
Scenario C (~20%): Breakthrough agreement on nuclear issues; Strait reopens; regional normalization begins. Iran makes verifiable commitments on uranium enrichment suspension and stockpile removal in exchange for sanctions relief. Saudi Arabia and Pakistan agree to normalize ties with Israel. The Strait of Hormuz returns to pre-war shipping levels within 60 days. Recommended action: Increase exposure to Middle East infrastructure and energy sectors; expect oil prices to decline to $60-70/barrel; engage in long-term regional investment.
Analytical Limitations
-
Incomplete visibility into Iranian decision-making. The Iranian Supreme Leader's approval of the MOU has not been confirmed, and Iran's semi-official news agencies have released conflicting versions of the agreement. The analysis relies on U.S. official statements about Iranian intentions, which may not reflect actual Iranian strategy.
-
Ambiguous ceasefire terms enable continued military action. Both sides are interpreting provisions around mine-laying, blockade scope, and "self-defense" strikes in ways that justify continued military operations. Without clearer definitions of ceasefire violations, the analysis cannot predict whether specific incidents will trigger escalation or de-escalation.
-
Trump's decision-making process remains opaque. Trump has deferred final approval of the MOU pending further consideration, but the criteria for his approval are unclear. His statements oscillate between military threats and diplomatic optimism, making it difficult to assess the probability of his signing the agreement.
-
Regional state positions are not fully known. Saudi Arabia, Pakistan, Egypt, and Jordan have not publicly confirmed their willingness to sign the Abraham Accords as a condition of the Iran deal. Their actual positions may differ from Trump's stated expectations, introducing a major source of uncertainty.
-
The scope of Israeli operations in Lebanon is not constrained by the MOU. Israel is not a formal party to the negotiations, and the U.S. has not secured Israeli commitment to halt operations. The trajectory of the Lebanon conflict could independently trigger Iranian escalation or withdrawal from negotiations.
