U.S.-Iran Ceasefire Stalls on Nuclear and Sanctions Terms

The U.S.-Iran ceasefire announced June 15, 2026, unfolds in phases rather than as a final agreement. Iran's tentative consent leaves sanctions relief and nuclear commitments unresolved. This separation creates vulnerability: the Strait of Hormuz remains operationally open while the underlying political framework stays incomplete, giving both sides room to reverse course before formal terms take hold.
