WASHINGTON: An emerging framework for ending the Iran-US conflict has triggered a sharp split among US lawmakers, with Republicans warning of strategic concessions and Democrats divided over diplomacy and enforcement risks.

The proposed arrangement, still unfinalised and subject to approval in Washington and Tehran, reportedly includes steps to restore maritime traffic through the Strait of Hormuz and establish a mechanism for addressing Iran’s stockpile of highly enriched uranium. However, core issues — including long-term enrichment limits, missile capabilities, and sanctions relief — remain unresolved and are expected to be deferred to later rounds of negotiations.

Senator Roger Wicker (R-MS), chairman of the Senate Armed Services Committee, warned that the reported arrangement could undermine recent US and allied military efforts.

“The rumored 60-day ceasefire — with the belief that Iran will ever engage in good faith — would be a disaster,” Wicker said in a post on X. He added that the effects of the joint US–Israel operation, referred to as “Operation Epic Fury,” would “be for naught” if the deal proceeded as described.
