Israeli Prime Minister Benjamin Netanyahu is on the mission of his lifetime. For years, the veteran leader has made the destruction of Iran’s nuclear program his top priority.

Israeli leaders say strikes on Tehran were necessary to head off an imminent threat that Iran would build nuclear bombs. Former Secretary of Defense Leon Panetta joins Ali Vitali to share why targeting Iran's nuclear sites is really difficult.

Iran fired hundreds of drones and ballistic missiles at Israel in two attacks last year in response to Israeli strikes, rattling the Israeli public but causing only modest damage. Tehran has vowed retaliation for Israel's early morning attack on Friday on Iranian military and nuclear facilities that killed several top commanders.
