Hillary Clinton runs State, not some nameless bureaucrats. The US isn't organized like Israel. Hillary isn't shy about her feelings about Iran. Neither is Obama. They just aren't in the mood for another war right now. Check back in a couple of years. There is no reason to assume the US would tolerate an Israeli attack that endangers US troops or civilians or our Navy. Your government knows this. Just because Obama lets people lie about him and tolerates insults from people claiming to be "friends," that doesn't mean getting US people killed by accident or design is going to be OK.
