The U.S.-Iran agreement ¡ª the first signed by an American and an Iranian president since Iran¡¯s 1979 Islamic Revolution ¡ª is being hailed by its backers as the deal of the century.

But for Tehran¡¯s adversaries across the Middle East ¡ª from Israel to Gulf states and factions in Lebanon ¡ª it looks more like the curse of the century: an accord that could leave Iran more secure, more legitimate and ultimately more influential.

U.S. President Donald Trump and Iranian President Masoud Pezeshkian signed the interim deal on Wednesday, ending a three-month war. Trump chose to ?formalize it at Versailles, on the sidelines of the Group of Seven summit ¡ª a setting widely seen as symbolic of the remaking of international order after conflict.
