Rubio Says Diplomacy Still An Option With Iran

Secretary of State Marco Rubio said the United States remains willing to negotiate with Iran, but warned that diplomacy cannot succeed while Tehran continues attacking commercial vessels and violating agreements intended to protect international shipping.

The latest remarks underscore the Trump administration’s two-track approach toward the Iranian regime: leave the door open to a legitimate peace agreement while maintaining overwhelming military pressure until Tehran changes its conduct.

President Donald Trump’s administration pursued negotiations, temporary ceasefires and other diplomatic efforts before the latest escalation. But the June 17 memorandum of understanding began collapsing after Iran resumed attacks on commercial vessels traveling through the Strait of Hormuz, prompting renewed American strikes on July 7.

Speaking to reporters Sunday night at Joint Base Andrews before departing for the ASEAN foreign ministers’ meeting in the Philippines, Rubio said Iran had effectively destroyed the agreement through its own actions.

The understanding was supposed to keep the Strait of Hormuz open to commercial traffic and prevent further attacks on civilian shipping. Instead, Rubio said Iran attacked three vessels late last week.

“I think we’re always open to diplomacy,” Rubio said.

“It has to be real. It has to be a deal that they’re willing to live by,” he said.

Rubio’s message was straightforward: An agreement cannot survive when one party openly refuses to honor its most basic provisions.

When reporters asked whether the memorandum of understanding was effectively dead, Rubio said Tehran had already answered that question.

“They’re not complying with it,” Rubio said.

“The straits are supposed to be open, free of tolls, free of attack, free of all the things they’re doing against these ships,” he continued, per Fox News.

“They can’t have an MOU that’s alive if they’re violating the terms of it.”

The Strait of Hormuz is one of the world’s most important energy corridors, and Iran’s attempts to control or disrupt passage through it threaten far more than American interests. The attacks place civilian sailors at risk, destabilize energy markets and give the Iranian regime leverage over countries that depend on oil and natural gas shipments moving through the region.

Despite Tehran’s conduct, Rubio said the United States has not abandoned the possibility of a peaceful resolution.

“The United States always remains open to a diplomatic solution,” Rubio said. “We’ve tried multiple times with Iran, and we’ll continue to try.”

That willingness to negotiate, however, does not mean Washington will reward aggression or accept another hollow agreement. Diplomacy requires enforceable commitments, not temporary promises that Tehran disregards whenever it believes violence will produce greater political leverage.

The renewed confrontation began after Iranian forces attacked commercial shipping in violation of the June agreement. Trump subsequently notified Congress that military hostilities had resumed and reinstated a blockade targeting Iranian shipping.

American forces then launched repeated strikes against Iranian military infrastructure surrounding the Strait of Hormuz and along Iran’s southern coast. The targets included air-defense systems, radar installations, anti-ship missile positions and drone-launching sites that U.S. officials said were being used to threaten commercial vessels.

Iran responded with missile and drone attacks against American positions and U.S. allies in the region, including sites in Jordan, Kuwait and Bahrain. The escalating exchange has severely reduced commercial traffic through the strait and raised new concerns about global energy security.

As the military campaign intensified, Trump convened his senior national security team for a Situation Room meeting on July 14 to discuss options extending beyond the strikes already being conducted near the strait.

According to Axios, the meeting included Vice President JD Vance, Rubio, Secretary Pete Hegseth, Chairman of the Joint Chiefs of Staff Gen. Dan Caine, CIA Director John Ratcliffe, White House envoy Steve Witkoff and other senior officials. The White House declined to comment publicly on the discussions.

The reported objective was to examine a broader campaign capable of inflicting enough damage on Iran’s military infrastructure to force the regime to reopen the Strait of Hormuz and accept American demands concerning its nuclear program.

At the time of the meeting, U.S. forces were conducting a fourth consecutive day of strikes around the strategic waterway. Officials said those operations were intended to reduce Iran’s ability to launch missiles, drones and other attacks against commercial shipping.

The United States also placed a naval blockade on Iranian ports, increasing economic and military pressure on Tehran while continuing to escort commercial traffic through the region.

Before entering the Situation Room, Trump warned that the campaign could become considerably more destructive if Iran continued rejecting negotiations.

“The U.S. military is going to hit Iran hard over the next three days,” Trump said during an interview with Fox News.

Trump’s warning reflected the central principle behind his administration’s strategy: Peace is more likely when America’s adversaries understand that aggression will carry an unbearable cost.

By Sunday, the renewed U.S. campaign had entered its ninth consecutive night. American strikes were targeting Iranian command centers, coastal surveillance systems, missile and drone sites, communications networks and other military infrastructure.

Still, Rubio’s remarks make clear that military pressure is not being treated as an end in itself. The administration’s stated objective remains an enforceable settlement that protects American personnel, keeps international shipping lanes open and prevents Iran from using its nuclear program or regional military power to threaten the United States and its allies.

The obstacle is not Washington’s unwillingness to negotiate. It is Tehran’s repeated pattern of entering agreements, violating their terms and then using renewed violence to demand additional concessions.

The Trump administration is therefore leaving Iran with a clear choice: Accept a genuine diplomatic agreement and honor it, or face continued military and economic pressure from a United States that is no longer willing to confuse empty promises with peace.
