U.S. Secretary of State Marco Rubio said on May 22, 2026 [1], that negotiations with Iran have shown slight progress but require more work.
The statements signal a precarious balance between diplomatic efforts and the threat of military or economic escalation. Because the Strait of Hormuz is a critical artery for global oil shipments, any prolonged closure could destabilize international energy markets.
Speaking at a press conference during a NATO meeting in Sweden [2], Rubio addressed the stalled negotiations regarding enriched uranium and the security of the strait. He said that while some movement has occurred, the U.S. is not yet at a final agreement [3].
Rubio emphasized the necessity of contingency planning to ensure the flow of global trade. "We need a Plan B if Iran keeps the Strait of Hormuz closed; someone's going to have to do something about it," Rubio said [2].
The Secretary of State also urged U.S. allies to increase their pressure on Tehran. He said that Europe must move beyond rhetoric and take concrete action against Iran [1]. This call for unified action follows a two-day visit [4] by Rubio to Italy and the Vatican.
Diplomatic timelines remain tight as the international community seeks a breakthrough. Reports indicate that the next round of talks is expected two days [5] after the latest U.S. message is presented to Iran. The U.S. objective remains a comprehensive deal that prevents the closure of the strait, while addressing nuclear concerns [3].
“There is slight progress in the talks with Iran.”
The U.S. is pursuing a dual-track strategy of diplomacy and deterrence. By acknowledging 'slight progress' while simultaneously demanding a 'Plan B,' the administration is signaling to Iran that diplomatic patience is not a substitute for security readiness. The emphasis on European action suggests the U.S. believes that multilateral economic or political pressure is the only way to force Iran to maintain the openness of the Strait of Hormuz.
