I'm not sure there's much to say about Sen. Clinton's threat to destroy the entire country of Iran with nuclear weapons if they first attack Israel with nuclear weapons other than it seems like garden-variety if unusually incendiary campaign rhetoric. But aren't we leaving out of this equation the fact that Israel has a large nuclear arsenal and one specifically designed (via the use of nuclear-armed submarines and other methods) to survive a first strike and still exact massive retaliation on an attacker? Israel has nuclear weapons. For precisely this purpose.
