United States President Donald Trump said on Monday that “numerous countries” had told him they were “on their way” to join an international naval coalition aimed at securing the Strait of Hormuz amid the ongoing US-Israel war on Iran. Trump did not identify any of the countries but said Secretary of State Marco Rubio would make an official announcement. He had earlier urged China, France, Japan, South Korea, and the United Kingdom, as well as NATO members, to participate in the coalition, though no country has yet confirmed involvement.

Several nations have publicly declined to send military ships, including Australia, Japan, Poland, Sweden, and Spain. Germany’s Defence Minister Boris Pistorius ruled out military participation but expressed support for diplomatic efforts. The UK and South Korea said they were reviewing options, with UK Prime Minister Keir Starmer suggesting possible deployment of mine-hunting drones while avoiding deeper engagement. France has shown more openness to assisting. Trump criticized countries that refused to join, noting that some were long-time US allies under American protection.

The conflict has sharply affected global oil markets, with prices rising 40–50 percent amid Iranian attacks on shipping. The UN reports 3.2 million people displaced in Iran, while Amnesty International accused the US of a deadly strike on a girls’ school in Minab.
