Israel passed information on an alleged Iranian plot to attack U.S. interests in the Gulf to the U.S. before national security adviser John Bolton threatened Iran with "unrelenting force" last night, senior Israeli officials told me.

Why it matters: Bolton's unusual and aggressive statement included news that the U.S. would move an aircraft carrier to the region. The officials said intelligence gathered by Israel, primarily by the Mossad intelligence agency, is understood to be part of the reason for Bolton's announcement.
