United States Secretary of State Marco Rubio has offered wide-ranging remarks upon his departure from the latest Group of Seven (G7) ministers’ meeting in France, denouncing Iran’s continued chokehold on the Strait of Hormuz as well as settler violence in the occupied West Bank.

Standing on an airport tarmac on Friday, Rubio fielded questions from journalists about reports that Iran plans to implement a tolling system in the strait, a vital waterway for the world’s oil supply.

Rubio used the topic to double down on pressure for countries to participate in securing the Strait of Hormuz, a demand US President Donald Trump has repeatedly made.

“One of the immediate challenges we’re going to face is in Iran, when they decide that they want to set up a tolling system in the Strait of Hormuz,” Rubio said.

“Not only is this illegal, it’s unacceptable. It’s dangerous for the world, and it’s important that the world have a plan to confront it. The United States is prepared to be a part of that plan. We don’t have to lead that plan, but we are happy to be a part of it.”

He called on the G7 members — among them, Japan, Canada, France, the United Kingdom, Italy, Germany and the European Union — as well as countries in Asia to “contribute greatly to that effort”.

Rubio calls toll plan ‘unacceptable’

The Strait of Hormuz is a key artery for the global transport of oil and natural gas, and prior to the start of the US and Israel’s war against Iran on February 28, an average of 20 million barrels of oil per day passed through the waterway.

That amounted to roughly 20 percent of the world’s liquid petroleum supply.

But since the outbreak of war, Iran has pledged to close the Strait of Hormuz, which borders its shores. The threat of attacks has ground most of the local tanker traffic to a standstill, though a few vessels, some linked to Iran or China, have been allowed to pass through.

Media reports suggest that Iran is setting up a “tollbooth system” that would require passing ships to put in a request through Iran’s armed forces, the Islamic Revolutionary Guard Corps (IRGC). There would also be a fee to secure passage.

“ They want to make it permanent. That’s unacceptable. The whole world should be outraged by it,” Rubio said on Friday.

He added that he conveyed a warning about the polling scheme to his colleagues at the G7.

“All we’ve said is, ‘You guys need to do something about it. We’ll help you, but you guys are going to need to be ready to do something about it,’” Rubio said.

“Because when this conflict and when this operation ends, if the Iranians decide, ‘Well, now we control the Strait of Hormuz and you can only go through here if you pay us and if we allow you to, that’s not only is it illegal under international law and maritime law. It’s unacceptable, and that can’t be allowed to exist.”

The Trump administration, however, has struggled to rally allies and world powers to join the US in its offensive against Iran.

Legal experts have criticised the initial strikes against Iran as an unprovoked act of aggression, though the Trump administration has cited a range of rationales for launching the attack, including the prospect that Iran may develop a nuclear weapon.

Many of the US allies in Europe have maintained that they would limit their involvement to defensive actions. Trump, meanwhile, has accused members of the NATO alliance of being “cowards”, adding in a social media post, “We will REMEMBER.”

In a statement following the G7 meeting, member countries reiterated their stance that there should be an “immediate cessation of attacks against civilians and civilian infrastructure”.

They also underscored the “absolute necessity to permanently restore safe and toll-free freedom of navigation in the Strait of Hormuz”. But the statement fell short of pledging any resources or aid to the US and Israeli war effort.

Achieving goals ‘without any ground troops’?

It is unclear when the war might end. On Saturday, it reaches its one-month anniversary, having stretched for four weeks.

Rubio on Friday echoed Trump’s assessment that the war was going as planned and that the US was achieving its objectives, including to destroy Iran’s navy, missile stockpiles and uranium enrichment programme.

“ We are ahead of schedule on most of them, and we can achieve them without any ground troops, without any,” he said, addressing an oft-raised concern about the prospect of US troops being deployed to Iran.

Rubio also briefly addressed the increasing levels of Israeli settler violence against Palestinians in the occupied West Bank.

Footage has shown settlers this month torching Palestinian homes and vehicles, as well as assaulting residents.

On March 19, the United Nations estimated that more than 1,000 Palestinians have been killed in the West Bank since Israel began its genocidal war in Gaza in October 2023. The international body underscored that a quarter of the victims were youths.

“ Well, we’re concerned about that, and we’ve expressed it. And I think there’s concern in the Israeli government about it, as well,” Rubio responded, adding that it was a “topic we follow very closely”.

He suggested that the Israeli government may take action to stop the violence, though critics argue that Israel has largely turned a blind eye to settler violence.

“Maybe they’re settlers, maybe they’re just street thugs, but they’ve attacked security forces, Israelis, as well. So, I think you’ll see the government going to do something about it,” Rubio said.

Upon taking office for a second term in January 2025, President Trump also moved to cancel sanctions against Israeli settlers accused of grave abuses in the West Bank.
