Out of desperation…..
"Iran has responded to a Fox News interview from late last week wherein Israeli Defense Minister Benny Gantz said that Israel is currently updating its plans to strike Iran’s nuclear program and is prepared to act independently if the United States is not willing. The interview was unusually blunt even for Israel in terms of the defense chief openly stating war plans.
Iranian Defense Minister Amir Hatami promptly fired back with a counterthreat on Sunday. He said Iran's military will level Tel Aviv and Haifa should Israel do anything "out of desperation".
