Switzerland's Foreign Ministry confirmed Tuesday that the signing ceremony for the memorandum of understanding between the United States and Iran will take place Friday at the Bürgenstock resort, a luxury alpine retreat overlooking Lake Lucerne, marking a dramatic acceleration of the diplomatic process that has roiled relations between Washington and Jerusalem.
The announcement came one day after American and Iranian negotiators finalized the preliminary text of the agreement, setting the stage for a formal signing that will reshape the nuclear standoff that has defined Middle Eastern security for two decades.
According to a senior U.S. official who briefed reporters on background, the memorandum will bear the signatures of President Donald Trump, Vice President JD Vance, and Iranian Parliament Speaker Mohammad Bagher Ghalibaf. Trump himself will not attend the ceremony, the official confirmed, with Vance leading the American delegation alongside White House advisers Steve Witkoff and Jared Kushner.
