U.S. President Donald Trump has failed to secure allied participation in maintaining open navigation through the strategic Strait of Hormuz. Both Australia and Japan have rejected his call for assistance in patrolling the vital global oil supply route. Australian Transport Minister Catherine King stated that her country would not send ships to the strait, emphasizing that Australia is already providing aircraft for defense support in the United Arab Emirates, considering the number of Australians in the region.

Japanese Prime Minister Sanae Takaichi told parliament that Tokyo has no plans to dispatch vessels to escort oil tankers through the strait. She added that Japan is still examining what actions it can take independently within its legal framework. Meanwhile, France said it is considering participation in an international mission to protect ships, but only after the ongoing conflict ends. Germany expressed skepticism about the plan and made clear it does not want to be directly involved in the war.

Iran has effectively blocked the narrow waterway, heightening tensions over global energy security and maritime safety in the region.
