A bit disappointed in Obama's response to Netanyahu's speech: "he didn't offer any new ideas" or however he phrased it.
Netanyahu was very clear on a "third way": increase the pressure and intensity of sanctions. They already had bite when oil was $100 / bbl, now at $50 / bbl, ramp them up even more, until the Iranians buckle.
Iran has already proven that it cannot be trusted, and they are arming Shiite groups across the Middle East (probably assisted by special forces operatives as well): in Gaza, Lebanon, Syria, Iraq, and Qatar, Iranian-backed forces are in control of substantial territory. Allow Iran to smuggle nuclear weapons to any of them, and boom!
