My own view is that if you have the power to delete your enemy while he's weak, you do it. Why the fuck would you wait until he gets the nukes he promises to get, or uses them on you like he also promises to do? At least the Israelis seem to understand this.
The US has already alienated their allies anyway, and as we've seen with this fiasco, it isn't like those allies are particularly useful anyway, so if the US did use nukes to very quickly solve what has been an intergenerational problem, so what? Oh no, condemnation from the international community. Nobody cares.
