Negotiations successfully extend the ceasefire! Both sides are willing to cut losses, the U.S. does not want to be trapped in the Middle East long-term, and U.S. military stockpiles are tight; Iran's economy has already been severely damaged, and a temporary agreement to reopen the strait may be reached, cooling the conflict.

Short-term stalemate + small-scale friction! The strait remains semi-closed, the U.S. continues limited blockade, both sides exchange words but avoid full escalation, dragging into next week.
Worst-case scenario: Iran refuses to negotiate + Trump fulfills threats, reigniting the conflict.
