US vice president launches media push to sell Iran agreement US Vice President JD Vance has launched a series of television appearances to promote and defend the agreement between Washington and Tehran amid mounting criticism and calls for greater transparency. In interviews with US media, Vance argued that the agreement would prevent Iran from obtaining a nuclear weapon while emphasising that key benefits for Tehran would depend on future compliance. Vance said the agreement had already been digitally signed, denied reports that Iran would immediately receive “billions of dollars of assets”, and insisted the United States retained leverage in future negotiations.
