The United Kingdom hosted a virtual summit Thursday with over three dozen countries seeking to establish a plan for reopening the Strait of Hormuz as a frustrated White House orders them to figure the issue out for themselves.

The evening before the meeting, President Donald Trump told allies that, since the American military has finished the “hard part” of “both militarily and economically” decimating Iran, “the countries of the world that do receive oil through the Hormuz Strait must take care of that passage.”
