Iran’s diplomatic engagement with Western powers has shifted focus from dismantling its missile capabilities to negotiating limits on uranium enrichment, while implicitly acknowledging Tehran’s strategic influence over the Strait of Hormuz, according to officials familiar with the talks.
The change in emphasis emerged during recent indirect negotiations in Oman, where European envoys pressed for verifiable caps on enrichment levels rather than demanding the rollback of Iran’s ballistic missile program, which had been a central demand in earlier rounds of diplomacy.
Western officials said the recalibration reflects a pragmatic assessment that Iran’s missile arsenal, while a regional concern, is less immediately tied to nuclear breakout timelines than its stockpile of near-weapons-grade uranium, which international monitors say has grown significantly since the collapse of the 2015 nuclear deal.
At the same time, diplomatic sources noted that any enduring agreement must account for Iran’s ability to disrupt shipping in the Strait of Hormuz, a chokepoint through which roughly 20% of global oil trade passes, and that Tehran has repeatedly signaled it could leverage this capability if pressured militarily or economically.
Iranian negotiators have not publicly conceded any limits on enrichment but have indicated willingness to discuss transparency measures in exchange for sanctions relief, according to summaries of the talks shared with European capitals.
The United States, while not directly participating in the Oman talks, has coordinated closely with European allies and reiterated that it will not accept an Iran capable of producing a nuclear weapon, though it has not ruled out enrichment below weapons-grade levels under strict verification.
No formal framework has been drafted, and officials on all sides caution that significant gaps remain, particularly over the duration of any limits and the sequencing of sanctions relief.
The next round of talks is scheduled for mid-May in Vienna, where technical experts will attempt to bridge differences on monitoring protocols and enrichment thresholds.
