Vienna — The United States and Iran resumed indirect nuclear talks this week in Vienna in an attempt to salvage a deal that would restrict Tehran’s nuclear program in exchange for sanctions relief, though fresh U.S. sanctions cast doubt over any breakthrough possibility.

Just days before talks began, the Biden administration issued new sanctions targeting Iranian defense firms and suspected arms shipments to proxy groups in the Middle East. Iran quickly condemned this move as evidence of bad faith that could set back progress before it even begins.

Diplomats from both nations remain cautiously hopeful that diplomacy can prevail, with talks focused on revitalising the 2015 Joint Comprehensive Plan of Action (JCPOA), which the U.S. walked away from under President Trump in 2018, leading Iran to breach its nuclear commitments.

“We remain committed to finding a peaceful resolution through diplomatic channels,” stated an official from the U.S. State Department, but Iran must take “verifiable steps” towards compliance with its obligations.

Iranian representatives have stressed the need for any new agreement to guarantee lifting sanctions and include safeguards against potential unilateral withdrawal by future U.S. administrations.

“We do not seek empty promises,” according to Iranian chief negotiator Ali Bagheri Kani. “What we want is an agreement which respects Iran’s rights under international law.”

Analysts assert that the road to an agreement remains difficult, due to mistrust on both sides, domestic political pressure, and regional instability that complicate the diplomatic landscape.

“The key question now is whether both parties are prepared to make enough concessions in order to break through this impasse,” noted Dr. Nadia Esfandiari, a Middle East policy expert. If not, she warned that we may be heading toward an extended standoff that has grave repercussions for global security.

As negotiations take place behind closed doors, the international community closely observes because nuclear proliferation, regional peace and economic stability are at stake.
