Netanyahu, along with his key cabinet ministers, such as Minister of Defense Ehud Barak and Vice Premier Moshe Ya'alon, has repeatedly referred to a nuclear Iran, or even a nuclear-capable Iran, as an unacceptable and existential threat to Israel. With virtually all Israelis agreeing that Iran should be prevented from acquiring nuclear weapons, there is an ongoing bitter debate among policymakers on how best to achieve this goal. Whilst the U.S. and Europe implement economic sanctions and pursue diplomatic solutions, the Israeli government carries out covert operations, such as computer viruses and assassinations of key Iranian scientists, designed to stall Iran's nuclear program.[1]
