US Faces Challenges in Nuclear Negotiations with Iran

The United States is set to begin negotiations with Iran over its nuclear programme, following the collapse of the previous agreement. The talks, expected to last an initial 60 days, come after a period of heightened tensions and military conflict between the two nations and their allies.

Analysts note that the strategic landscape has shifted significantly since the 2015 nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA). Under that accord, Iran agreed to limit its uranium enrichment to 3.67% in exchange for sanctions relief. The United States withdrew from the deal in 2018 under President Donald Trump, leading Iran to gradually abandon its commitments. The International Atomic Energy Agency has reported that Iran is now enriching uranium to 60% purity, well above the previous cap.

In February 2025, the US and Israel launched a military campaign against Iran that lasted until an April ceasefire. The stated objectives included dismantling Iran's missile capabilities, preventing nuclear weapon development, and halting support for proxy forces. While the campaign damaged Iran's nuclear facilities and navy, the government of Iran survived the assault, a factor analysts say has altered the power dynamics in the negotiations.

“It's a much worse situation strategically for the US now than it was back in the 2010 to 2015 time period,” said Alan Eyre, a former negotiator of the 2015 deal and a distinguished diplomatic fellow at the Middle East Institute. He noted that the Iranian nuclear programme is more advanced, and bilateral trust is significantly diminished.

A memorandum of understanding signed by President Trump and Iranian President Masoud Pezeshkian on Wednesday states that Iran “reaffirms that it shall not procure or develop nuclear weapons,” but does not specify verification or enforcement mechanisms. The document also includes provisions for a $300 billion reconstruction fund for Iran, the lifting of a US naval blockade, and sanctions waivers for Iranian oil exports. Notably, it does not address Iran's missile programme or its support for regional proxies.

Critics argue that the emerging deal represents a significant concession to Tehran. Richard Haas, president emeritus of the Council on Foreign Relations, described it as a “massive victory” for the Iranian government, suggesting that financial relief would strengthen its domestic control and ability to rearm.

President Trump has defended the agreement, calling detractors “fools” and “jealous, bad people.” Vice President JD Vance characterized the deal as a “win-win situation for the United States.”

However, Eyre expressed scepticism about the prospects of a more favourable outcome than the 2015 deal. “The US should be so lucky as to get as good a deal as Obama,” he said, adding, “If we're trying to get Iran to walk back its nuclear program to where it was in 2018 when we pulled out, that is, I think, a bridge too far.”

The negotiations are expected to continue amid ongoing international scrutiny and regional instability.
