Israeli Defense Minister (and former PM) Ehud Barak has told one of Israel's leading dailies, Yedioth Ahronoth, that an Iran with nuclear weapons would not pose an existential threat to Israel. And PM Netanyahu, albeit cautiously and more opaquely, says he agrees with him.

The argument is pretty elementary. Whatever nuclear capacity Iran may have, Israel's deterrent capacity is so overwhelming that it can deter any nuclear attack. It's what most people already think. But having it said by the Israeli Defense Minister sounds a very different note.
