The question now will Netenyahu follow up on his threat and if so when and how will Iran and the rest of the world respond.
There is another part to the question: what will Obama do to hinder and prevent a response by Netanyahu to this imminent existential threat? Obama does not want any “disruption” to his plan to elevate Iran to world power status. He is hell bent on allowing it to become a regional power. That much is perfectly clear.
