The geopolitical standoff between the United States and Iran has reached a critical juncture. While President Donald Trump has expressed a desire to reach a new agreement to curtail Iran’s nuclear program and stabilize the Strait of Hormuz, the path to diplomacy is fraught with structural and credibility hurdles.
In a recent discussion on Today, Explained, Wendy Sherman —the former Deputy Secretary of State who played a pivotal role in negotiating the 2015 Joint Comprehensive Plan of Action (JCPOA)—provided an expert analysis of why current efforts face such steep resistance and what is at stake for global stability.
The Fundamental Clash of Objectives
For any negotiation to succeed, both parties must have overlapping interests. Currently, the objectives of Washington and Tehran appear fundamentally at odds:
- The U.S. Agenda: The Trump administration aims to prevent Iran from acquiring nuclear weapons, ensure the free flow of oil through the Strait of Hormuz, and curtail Iran’s funding of regional proxies such as Hezbollah, Hamas, and the Houthis.
- The Iranian Agenda: Tehran seeks to maintain its leverage over the Strait of Hormuz, preserve its right to uranium enrichment, and continue supporting its regional allies to project power.
This “gap” is exacerbated by a disparity in negotiating experience. While the U.S. team is currently small, Iran’s delegation includes seasoned diplomats like Foreign Minister Abbas Araghchi, who was a central figure in the 2015 negotiations and possesses an intimate knowledge of the previous deal’s mechanics.
Lessons from the 2015 Nuclear Deal
Sherman addressed the common criticisms leveled against the original Obama-era deal, specifically the argument that it was too short-term.
“The critics say that the strongest part of the deal only lasted for 15 years. They wanted it to last forever,” Sherman noted.
She explained that the deal was designed with a “one-year breakout timeline.” This provided the international community a window of time to react if Iran were discovered to be cheating. Furthermore, Sherman highlighted that the alternative to such diplomacy—pursuing regime change through military force—carried catastrophic risks, including the closure of the Strait of Hormuz, spikes in global gas prices, and massive economic and human costs.
The Credibility Gap in Current Negotiations
A significant obstacle to a new deal is the perceived lack of credibility of the current U.S. negotiating team. Sherman expressed skepticism regarding the effectiveness of figures like Vice President JD Vance, Steve Witkoff, and Jared Kushner.
The core issue is diplomatic trust. Sherman pointed out that because previous negotiation attempts were met with sudden escalations and attacks, Iranian officials may be unwilling to return to the table with representatives they view as inconsistent. Without established diplomatic rapport, the likelihood of a lasting agreement diminishes.
The Cost of Diplomatic Instability
The consequences of the current impasse extend far beyond the Middle East. Sherman argues that the breakdown of previous agreements has resulted in several strategic setbacks for the United States:
- Economic Burden: The instability contributes to higher costs for everyday Americans through energy market volatility.
- Strategic Weakening: The U.S. has depleted weapon inventories and undermined long-standing alliances.
- Geopolitical Shifts: The current landscape has inadvertently strengthened the positions of Russia and China. Furthermore, the easing of certain sanctions has provided much-needed revenue to regimes engaged in conflict, such as Russia’s war in Ukraine.
- Nuclear Proliferation: As Iran becomes more hardline, the pressure to acquire a nuclear deterrent grows. If Iran successfully develops a weapon, it could trigger a nuclear arms race among other regional powers and even close U.S. allies.
Conclusion
The struggle to negotiate with Iran is not merely a technical dispute over enrichment levels, but a fundamental battle over regional influence and diplomatic trust. Without a credible framework that addresses the core security concerns of both nations, the risk of nuclear proliferation and global economic instability continues to rise.
