US and Iran Agree to Tentative Peace Deal and Reopening of the Strait of Hormuz
The United States and Iran have reached a landmark preliminary peace agreement, concluding more than 100 days of active war and initiating the reopening of the crucial Strait of Hormuz. US President Donald Trump and Iranian officials finalized a 14-point memorandum of understanding (MOU) that establishes a framework to end the conflict, lift the US naval blockade on Iranian ports, and extend the current ceasefires in Iran and Lebanon.
While Trump enthusiastically declared that "the deal's all signed" upon arriving at the G7 Summit in Évian-les-Bains, France, the agreement is set for a formal signing ceremony in Geneva, Switzerland, on Friday, June 19, 2026. The ceremony will be attended by US Vice President JD Vance and Iran's chief negotiator, Mohammad-Bagher Ghalibaf.
Despite the breakthrough, the agreement contains significant friction points and unresolved issues that will be pushed to a secondary phase of intense negotiations123:
- The Shipping Toll Dispute: A major disagreement has emerged regarding the mechanics of the Strait of Hormuz. Iranian officials insist that last-minute changes to the MOU grant Iran the right to charge fees for maritime services4 within the waterway. Trump has flatly rejected this, asserting that the agreement ensures the strait remains "toll-free."
- Sanctions and Asset Unfreezing: White House officials clarified that no frozen Iranian assets have been released yet, stating that future sanctions relief and asset unfreezing will be strictly transactional and tied to "Iran meeting their commitments."
- Force Posture: The US military will not immediately draw down its forces near Iran, maintaining its current posture to ensure compliance during the next phase of negotiations.
- Israeli Opposition and Ceasefire Breaches: The ceasefire is highly fragile. Although Trump reportedly applied heavy pressure to halt Israeli strikes in Lebanon, Israel has already conducted drone strikes in southern Lebanon, resulting in casualties.5 Israeli Prime Minister Benjamin Netanyahu distanced himself from the negotiations, calling it "Trump's decision," while far-right members of his coalition, including National Security Minister Itamar Ben-Gvir, declared that the agreement does not bind Israel and called for ignoring it entirely.6
