The U.S. went to war without its allies. Now it wants their help

President Trump launched the war against Iran without building a coalition of U.S. allies. Only now is the president trying to enlist allies to help end Iran’s effective shutdown of the Strait of Hormuz. And many of the countries he’s asked – are rejecting Trump’s request. Can the U.S. get its allies to help after going to war with Iran, and if they do, can the Strait of Hormuz really be secured?
