Israel's leadership calls Iran an existential threat, but a large majority of Israelis are against a strike if it's carried out by Israel alone. Most analysts agree that an Israeli strike could not end Iran's nuclear program, only set it back. And some argue an attack would cement Iran's determination to develop a nuclear weapon which could start an arms race in the region.
The biggest critic of Israel's threats of a strike has been Meir Dagan, the former head of Israel's foreign security service, Mossad. He has argued that Iran is not an existential threat and that its leadership is rational. In a Wall Street Journal op-ed on Thursday, he and other former international intelligence and military officials argued that more comprehensive "total sanctions" can get Iran to change course.
"It's common sense that before undertaking military action against a country, we should first try to dissuade it from its current course by applying decisive economic pressure," they write. "Doing so will show the regime that the world is serious and committed, willing to do whatever it takes to stop Iran's pursuit of nuclear weapons."
