The landmark agreement aimed at curbing Iran's nuclear program has effectively ended ahead of its scheduled conclusion, following the reimposition of wide-ranging United Nations sanctions. The deal, once seen as a diplomatic breakthrough, began unraveling after the United States withdrew in 2018 and reinstated sanctions, prompting Iran to expand its nuclear activities. Recent efforts by European powers to revive the agreement have failed, and the so-called 'snapback' of sanctions has officially buried the deal, leaving future negotiations uncertain. Experts suggest that while the collapse of the agreement casts a shadow over diplomatic efforts, it may also open the door for new approaches to address the ongoing nuclear crisis, though the risk of conflict remains high if talks do not resume soon.
