Glad you posted this because this is just one more example of the Israelification of the United States. Hillary was the first to suggest using a nuclear option against Iran, even before Israel who daily posit the existential threat of Iran and much to the dismay of many military leaders in the US.
The ultimate current threat of Iran is not that it is seeking first strike capability, in fact our own intelligence agencies point out that the bulk of Iranian military tech is that of self defense, the real threat is economic displacement of the Gulf States, typically that of Saudi Arabia, Qatar, Bahrain, portions of Yemen.
When Israel adjoins with Saudi Arabia to allow air strikes into Iran, what does this tell you? Israel the sworn and worst possible enemy of anything Islamic has secured a deal with the most radical supporters of ISIS to undermine Iran.
Iran is a lot of things and has a population of 3 times that of Iraq, so listen to HIllary and I can only recommend you make a few babies to fight a war that will not end in our lifetime.
