"What we want to do is to send a message to whoever is making these decisions, that if you're pursuing nuclear weapons for the purpose of intimidating, of projecting your power, we're not going to let that happen.
First, we're going to do everything we can to prevent you from ever getting a nuclear weapon. But your pursuit is futile, because we will never let Iran — nuclear-armed, not nuclear-armed — it is something that we view with great concern, and that's why we're doing everything we can to prevent that from ever happening. ... We believe, as a matter of policy, it is unacceptable for Iran to have nuclear weapons."
