The United Kingdom's Prime Minister Keir Starmer has discussed the issue with Donald Trump and Canadian Prime Minister Mark Carney. The European Union is considering bolstering its Aspides naval mission but is not expected to expand its role to the Strait of Hormuz, with Germany expressing skepticism about such an extension.
