Washington seeks a comprehensive deal as Tehran pushes phased talks, keeping nuclear tensions unresolved
April 28, 2026: Donald Trump is reportedly unwilling to accept Iran’s proposal to end the ongoing conflict, as the plan sidesteps critical issues related to Tehran’s nuclear programme. While the proposal includes reopening the Strait of Hormuz, US officials believe it fails to address core concerns upfront. Washington is instead pushing for a comprehensive agreement that directly tackles nuclear activities, highlighting deep divisions between the two sides and casting doubt on the prospects of a quick diplomatic resolution.
The proposal has met immediate resistance in Washington, where officials insist that any agreement must include firm commitments on nuclear restrictions. Iran’s foreign minister Abbas Araghchi has reportedly conveyed Tehran’s “red lines,” including limits on uranium concessions and demands for sanctions relief. Meanwhile, Vladimir Putin confirmed receiving a message from Iran’s leadership, signalling intensified diplomatic activity. At the same time, German Chancellor Friedrich Merz criticised the US stance, warning that Washington risks diplomatic setbacks without a broader agreement.
Key sticking points remain unresolved, including Iran’s nuclear programme, uranium stockpile, sanctions relief, and regional influence. The US is demanding stricter controls and a rollback of Iran’s support for regional allies, while Tehran is seeking economic relief and compensation for damages. As tensions persist, global concerns are rising over the stability of energy markets, especially with the strategic importance of the Strait of Hormuz and its role in global oil supply.
