The United States is struggling to build a coalition of countries to reopen the critical Strait of Hormuz, a crucial issue for the White House as long as the Iranian blockade holds and Gulf oil remains trapped. The White House is using both military and diplomatic means to resolve the crisis, including strikes on Iranian anti-ship positions along the shores of the Strait of the strait. The coalition includes the U.K., France, Germany, Italy, Australia, Canada, the Gulf countries and Jordan. However, the leaders of countries such as Germany and Italy have ruled out sending naval vessels. The U.S. military has also approached Japan and South Korea. European diplomats have expressed confusion over the coalition's approach, while European foreign policy chief Kaja Kallas said there is no appetite in the EU to join.
