President Donald Trump has called on five countries, including China, France, Japan, South Korea, and the United Kingdom, to reopen the Strait of Hormuz. However, these efforts have not been met with enthusiasm from the United States allies, who prefer to ignore the ongoing war with Iran. This comes after Trump warned that NATO faces a "very bad" future if allies stop helping the US. The European Union has expressed support for opening the strait, but did not go as far as saying action was imminent. It is unclear if the U.K. will act.
