IDF Chief of Staff Lieutenant-General Gabi Ashkenazi said Wednesday night that sanctions were the preferable way to deal with the Iranian threat, but that Israel must prepare for any scenario. "We are all united in thinking that Iran should not be allowed to obtain nuclear weapons, and there is no doubt that the preference is for diplomatic activity and sanctions. This is the Israeli and the American preference. But everyone understands, both the Americans and certainly us, that all options must be prepared for," Ashkenazi told reporters in Washington.
