ALBAWABA - The Lebanon crisis has overtaken the nuclear file, which had been expected to dominate the talks, and become the main issue in a fresh round of U.S.-Iran negotiations in Switzerland.

Negotiators from Washington and Tehran began direct talks at the Bürgenstock resort on Sunday, days after reaching a framework deal to cease hostilities between the two nations and pave the way for further talks on Iran’s nuclear program. But increased conflict between Israel and Hezbollah rapidly became the main topic of discussion.

Iranian diplomats entered the discussions saying the issue in Lebanon must be addressed immediately, saying ongoing Israeli military activity poses a threat to regional stability and the broader peace process. Tehran has accused Israel of violating its promises under the framework agreement recently inked and warned the conflict could derail the progress accomplished so far.

The American delegation, led by Vice President J.D. Vance, arrived at the meetings hoping to see progress on the Lebanon ceasefire attempt as well as the long-running issue over Iran’s nuclear program. Officials on both sides admitted that what happens on the battlefield is more and more dictating the pace and direction of diplomatic conversations. 

The discussions are taking place under a framework agreement that promised both governments to pursue a full settlement within 60 days. The deal includes terms on reopening the Strait of Hormuz, sanctions relief and future talks on Iran’s nuclear program. But the recent round of fighting in Lebanon has complicated such preparations and created fears that diplomacy can't keep up with developments on the ground.

Iran delayed its participation in the talks briefly following a fresh round of Israeli attacks in Lebanon but agreed to participate after insisting that halting the conflict would be a primary aim of the discussions.

“Nuclear issues are an important part of the negotiations, including the future of uranium enrichment and sanctions policy, but diplomats say both sides have made it an immediate priority to bring stability to Lebanon.

The increasing emphasis on Lebanon illustrates the extent to which regional problems continue to influence the broader relationship between Washington and Tehran. As discussions continue in Switzerland, negotiators are challenged to avoid letting the crisis in Lebanon disrupt efforts to secure a broader diplomatic breakthrough on Iran’s nuclear program and regional stability.
