A memorandum of understanding was signed between the United States and Iran on Wednesday, with terms including removal of the US naval blockade, reopening of the Strait of Hormuz, an Iranian commitment against nuclear weapons, and termination of military operations including in Lebanon. JD Vance defended the agreement at a White House briefing and had planned talks in Switzerland that were later postponed for logistical reasons. President Trump had stated the previous day that he might blame the vice president if the deal collapses.
