US-Iran Deal Tested as Lebanon Clashes Escalate, Talks Delayed

The United States and Iran have confirmed the signing of a memorandum of understanding (MoU), but many Iranians remain skeptical that Washington will fully honor its commitments. Some fear the deal may not deliver lasting stability and could eventually break down.

Iran’s Supreme Leader approved the MoU after receiving assurances that Iran’s national interests and regional allies would be protected. He stressed that direct talks with the US do not mean Iran accepts US positions and warned against any excessive demands.

Iranian Parliament Speaker Mohammad Bagher Ghalibaf said Tehran will continue to uphold its red lines and defend national interests. He warned that any violation of the agreement by the other side would trigger a strong Iranian response.

Regional tensions remain high after reports of Israeli strikes and clashes with Hezbollah in southern Lebanon. Iran warned that continued attacks in Lebanon could lead to the suspension of negotiations and threaten the broader diplomatic process.

Iran has postponed its planned negotiating trip to Switzerland, saying developments in Lebanon remain closely linked to future talks. Separately, US Vice President JD Vance also canceled his planned visit to Switzerland, while technical discussions between the two sides are expected to continue.

Pakistan’s Prime Minister Shehbaz Sharif has also canceled a planned trip to Switzerland without providing a reason. Meanwhile, Vance criticized Israeli opposition to the MoU, saying some Israeli leaders do not trust Washington’s approach toward Iran. Iran has accused the US of responsibility for ceasefire violations and warned that further escalation could jeopardize the agreement.
