Barak: ‘Iran may become an existential threat to Israel’

I thought Iran already was Israel’s existential threat. Defense Minister Ehud Barak told IDF officers Sunday:

“A nuclear Iran is without a doubt the main threat to world order and may lead to mass nuclear proliferation in the entire Middle East. Iran may become an existential threat to Israel.”

“Should Iran obtain nuclear weapons, the sense of security among elements that are affiliated with (the Islamic Republic) will increase immensely, and this will lead to the collapse of the non-proliferation regime and the struggle against nuclear armament in the region.”
