Washington, May 23, 2026 – U.S. Secretary of State Marco Rubio has urged the development of a contingency “Plan B” to ensure the reopening of the Strait of Hormuz if Iran continues to refuse cooperation on international shipping access.
Speaking at a NATO foreign ministers meeting in Helsingborg, Sweden, Rubio expressed cautious optimism about ongoing diplomatic efforts with Iran, which include discussions on nuclear issues and the critical waterway. However, he emphasized the need for preparedness in case diplomacy fails.
“We prefer a diplomatic solution where Iran reopens the strait for international shipping,” Rubio stated. He highlighted that while allies are working toward a peaceful resolution, contingency measures are essential. “At some point, ideally, they open the strait… Plan B needs to be, what if Iran says, ‘No, we refuse to open the Strait?’… then someone’s going to have to go in and do something about it.”
Rubio specifically criticized any potential Iranian imposition of tolls on vessels passing through the strait, describing such actions as illegal. He referenced a UK and France-proposed mission designed for scenarios “when no one is shooting,” but stressed that the United States must be ready for situations involving active threats.
Strategic Importance of the Strait
The Strait of Hormuz serves as a vital chokepoint connecting the Persian Gulf to the Gulf of Oman. Approximately 20-30% of the world’s oil and liquefied natural gas (LNG) transits through this narrow passage daily, making it one of the most strategically significant maritime routes globally.
Tensions in the region have escalated in recent weeks following conflicts involving Iran, including reported threats to commercial shipping and mining activities. These developments have contributed to volatility in global oil prices.
The remarks reflect the current U.S. administration’s dual-track approach toward Iran: pursuing diplomatic negotiations while maintaining strong military readiness in coordination with NATO allies. No specific operational details regarding “Plan B” were disclosed publicly, with officials framing it as necessary operational planning rather than an immediate escalation.
The situation remains fluid, with international attention focused on whether diplomatic channels can resolve the impasse before further action becomes necessary.
