TEHRAN — Speculation is mounting over the content of nuclear talks between Iran and the United States amid reports that the two sides are preparing to resume diplomacy. 

While reports in Western media suggested that White House envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi, alongside representatives from several Arab countries, were set to meet on Friday, Iranian officials have yet to formally confirm the time and venue. 

Iranian President Masoud Pezeshkian publicly acknowledged the diplomatic track in an X post on Tuesday. However, he conditioned the talks on the absence of US "threats and unreasonable expectations" and said they must be "based on dignity, prudence and expediency … within the framework of our national interests." Pezeshkian confirmed having instructed Araghchi in the negotiations and noted that the decision to pursue diplomacy was in response to "requests from friendly governments in the region."

Yet even as Tehran signals openness to diplomacy, senior figures within Iran's security establishment have drawn firm red lines — particularly over the thorny issue of Iran's enriched uranium stockpile — that could threaten to derail talks before they begin.
