Biden says he's not concerned Israel will launch attack on Iran

In an Tuesday with CNN, US Vice President Joe Biden was asked how worried he is that Israel, under Netanyahu, will launch a strike to take out Iran's nuclear facilities. "I don't believe that Prime Minister Netanyahu would do that," Biden said. "I think he would be ill-advised to do that. And so my level of concern is no different than it was a year ago." Biden was interviewed on CNN's "The Situation Room With Wolf Blitzer."
