The United States committed on June 18, 2026, to end all sanctions on Iran and pledged to develop a $300 billion plan with regional partners for Iran's reconstruction and economic development, while also lifting its blockade of Iranian ports and waiving sanctions to allow Iran to earn from oil exports
What's happening
According to the memorandum of understanding signed on June 18, 2026, in Islamabad, the implementation mechanism for these measures is to be finalized within 60 days.
Where the evidence points
The US will need to seek congressional approval for the $300 billion reconstruction commitment, either as a formal appropriation request, authorization for fund release, or sanctions waiver legislation, making full delivery without Congress politically and legally impossible.
Key drivers
- A $300 billion commitment explicitly tied to US facilitation makes congressional approval more likely necessary than avoidable, distinguishing this hypothesis from the no-Congress-needed view.
- Sanctions waiver of this magnitude typically requires congressional action or notification under IEEPA, strengthening the case that Congress must approve the broader $300 billion commitment.
Evidence on this has been independently challenged and assessed.
Key questions
▸
Is the US blockade actually being removed now, or only if Iran meets nuclear deal terms?
Evidence suggests: Blockade is being lifted now, no conditions attached
Our leading answer changed on Jun 25: Blockade removal depends on Iran keeping nuclear promises → Blockade is being lifted now, no conditions attached. Cause: new evidence.
Ranks compare these explanations against each other; the parenthetical is how likely each one is on its own.
Weighing the available reporting, these explanations rank by evidence:
Most likely: Blockade is being lifted now, no conditions attached (possible)
Best case for Blockade is being lifted now, no conditions attached
- US Vice President JD Vance announced that the United States has lifted its blockade of Iranian ports.
- The United States committed on 18 June 2026 to immediately remove the naval blockade and any obstacles imposed on Iran upon signing the memorandum, and complete the blockade's elimination within 30 days, with ship traffic levels returning to pre-war levels.
- The United States undertook to begin removal of its naval blockade on Iran immediately upon signing the Islamabad Memorandum of Understanding on 18 June 2026 and fully end it within 30 days.
For: Blockade is being lifted now, no conditions attached
- The United States committed on 18 June 2026 to immediately remove the naval blockade and any obstacles imposed on Iran upon signing the memorandum, and complete the blockade's elimination within 30 days, with ship traffic levels returning to pre-war levels. Commitment to 'immediately remove' blockade 'upon signing' and 'complete elimination within 30 days' proves unconditional immediate lifting. 1 source, verified
- US Vice President JD Vance announced that the United States has lifted its blockade of Iranian ports. VP Vance's announcement that blockade 'has been lifted' confirms removal as accomplished fact, not future contingency. 1 source, primary
- The United States dropped its naval blockade of Iran on 18 June 2026. Observed fact that US dropped blockade on June 18, 2026, directly proves immediate unconditional lifting. 1 source, multiple independent
- The United States undertook to begin removal of its naval blockade on Iran immediately upon signing the Islamabad Memorandum of Understanding on 18 June 2026 and fully end it within 30 days. Statement that US 'undertook' removal 'immediately upon signing' and 'fully end it within 30 days' directly supports blockade lifted now without conditions. 1 source, verified
Challenging evidence
- The agreement commits the United States to facilitate the release of a $300 billion reconstruction fund supported by regional nations once a final agreement is reached on Iran's nuclear program. The $300 billion fund explicitly requires 'once a final agreement is reached,' contradicting immediate unconditional removal. 1 source, verified
- The United States will lift its naval blockade on Iran within 30 days and remove its forces from proximity to Iran within 30 days after the final agreement, according to the Islamabad Memorandum of Understanding. Blockade removal 'within 30 days after the final agreement' ties it to nuclear deal completion, not immediate unconditional action. 1 source, verified
- The United States agreed to adopt a phased sanctions relief pathway linked to progress in final negotiations. Phased relief 'linked to progress' in negotiations contradicts the claim that removal is immediate and unconditional. 1 source, multiple independent
Less likely: Blockade removal depends on Iran keeping nuclear promises (very unlikely)
Best case for Blockade removal depends on Iran keeping nuclear promises
- The United States will lift its naval blockade on Iran within 30 days and remove its forces from proximity to Iran within 30 days after the final agreement, according to the Islamabad Memorandum of Understanding.
- The United States agreed to adopt a phased sanctions relief pathway linked to progress in final negotiations.
- The agreement commits the United States to facilitate the release of a $300 billion reconstruction fund supported by regional nations once a final agreement is reached on Iran's nuclear program.
For: Blockade removal depends on Iran keeping nuclear promises
- The agreement commits the United States to facilitate the release of a $300 billion reconstruction fund supported by regional nations once a final agreement is reached on Iran's nuclear program. Fund release 'once a final agreement is reached' shows blockade removal is part of conditional, phased process tied to nuclear compliance. 1 source, verified
- The United States blockade of Iranian ports will reduce in enforcement intensity, allowing routine commercial traffic through the Strait of Hormuz. Reduced enforcement 'allowing routine commercial traffic' fits interpretation that blockade removal is phased and progress-dependent. 1 source, analysis
- The United States will lift its naval blockade on Iran within 30 days and remove its forces from proximity to Iran within 30 days after the final agreement, according to the Islamabad Memorandum of Understanding. Blockade and force removal 'within 30 days after the final agreement' proves lifting is conditional on nuclear deal, not immediate. 1 source, verified
- The United States agreed to adopt a phased sanctions relief pathway linked to progress in final negotiations. Phased sanctions relief 'linked to progress' in negotiations directly supports blockade removal being conditional on nuclear compliance. 1 source, multiple independent
Challenging evidence
- The United States committed on 18 June 2026 to immediately remove the naval blockade and any obstacles imposed on Iran upon signing the memorandum, and complete the blockade's elimination within 30 days, with ship traffic levels returning to pre-war levels. Immediate removal commitment conflicts with interpretation that full, irreversible lifting requires final nuclear agreement verification. 1 source, verified
- US Vice President JD Vance announced that the United States has lifted its blockade of Iranian ports. VP's announcement of lifted blockade contradicts hypothesis that full removal awaits nuclear agreement completion. 1 source, primary
- The United States dropped its naval blockade of Iran on 18 June 2026. Observed fact of dropped blockade on June 18 contradicts hypothesis that removal depends on future nuclear compliance. 1 source, multiple independent
- The United States undertook to begin removal of its naval blockade on Iran immediately upon signing the Islamabad Memorandum of Understanding on 18 June 2026 and fully end it within 30 days. Language of immediate undertaking 'upon signing' suggests blockade removal begins now, not only after nuclear agreement completion. 1 source, verified
Least likely: The blockade is announced lifted but still largely enforced (almost certainly not)
Best case for The blockade is announced lifted but still largely enforced
- US Vice President JD Vance announced that the United States has lifted its blockade of Iranian ports.

- The United States committed on 18 June 2026 to immediately remove the naval blockade and any obstacles imposed on Iran upon signing the memorandum, and complete the blockade's elimination within 30 days, with ship traffic levels returning to pre-war levels. Commitment to 'immediately remove' blockade supports narrative that announcement occurs now while enforcement continues pending agreement. 1 source, verified
- US Vice President JD Vance announced that the United States has lifted its blockade of Iranian ports. VP's announcement of lifted blockade fits narrative where blockade is rhetorically lifted while operational enforcement persists. 1 source, primary
- The United States undertook to begin removal of its naval blockade on Iran immediately upon signing the Islamabad Memorandum of Understanding on 18 June 2026 and fully end it within 30 days. Commitment to 'begin removal immediately' and 'fully end it within 30 days' describes announced action, consistent with announced-but-enforced hypothesis. 1 source, verified
- The United States agreed to adopt a phased sanctions relief pathway linked to progress in final negotiations. Phased relief pathway 'linked to progress' supports partial announcement strategy maintaining leverage through selective enforcement. 1 source, multiple independent
- United States Central Command allowed more than a dozen ships to pass through the US naval blockade of Iranian ports. Only 'more than a dozen ships' allowed through—small number supporting interpretation that blockade remains largely enforced despite announcement. 1 source, named source
Challenging evidence
- The United States dropped its naval blockade of Iran on 18 June 2026. If the blockade was dropped on June 18, 2026, it cannot be 'announced lifted but still largely enforced'—these are incompatible claims about whether enforcement actually stopped. 1 source, multiple independent
- Under the Islamabad Memorandum of Understanding, the United States will lift its naval blockade of Iranian ports. A commitment to lift the blockade contradicts the claim that it remains substantially enforced despite the announcement, unless 'lift' is read as purely rhetorical rather than operational. 1 source, named source
- The United States committed on 18 June 2026 to end all sanctions imposed on Iran including UN Security Council resolutions, IAEA Board of Governors decisions, and all unilateral US primary and secondary sanctions according to a timeline agreed in the final agreement. Commitment to end all sanctions contradicts hypothesis that secondary sanctions and asset freezes remain in effect. 1 source, verified
- The United States will lift its naval blockade on Iran within 30 days and remove its forces from proximity to Iran within 30 days after the final agreement, according to the Islamabad Memorandum of Understanding. The 30-day timeline and post-agreement contingency contradict a hypothesis that blockade removal is announced but still largely enforced in practice—the memorandum explicitly commits to removal, not ongoing enforcement. 1 source, verified
- The Strait of Hormuz has reopened to commercial shipping. Strait of Hormuz reopened to commercial shipping contradicts hypothesis that blockade remains largely enforced in practice. 1 source, named source

- The United States undertook to develop with regional partners a definitive plan with at least USD 300 billion for reconstruction and economic development of Iran, with implementation mechanism to be finalized in the final deal within 60 days of the Islamabad Memorandum of Understanding signed on 18 June 2026. The memorandum explicitly states the $300 billion fund is developed 'with regional partners,' directly supporting the idea that partners share the load, not the US alone. 1 source, verified
Challenging evidence
- The United States pledged to develop a definitive, mutually agreed plan to provide $300 billion in funds for the reconstruction and development of Iran. The pledge to provide $300 billion in US funds contradicts a hypothesis that partners cover most of it, though burden-sharing could still reduce the US share. 1 source, primary
