The United States views Iran’s threat to attack Israel as “credible.” White House correspondent Greg Clugston reports. National Security spokesman John Kirby isn’t discussing intelligence details or timelines, but says “we do believe this still is a viable threat.” Kirby says the U-S is communicating with Israel about making sure they can defend themselves against an Iranian attack. Israel’s military said it’s ready if Iran retaliates for a deadly airstrike on the Iranian Consulate in Syria.
