Well good luck with that, at the moment, other than Lebanon and Syria which are sponsored by Iran, every single country in the ME strongly opposes a nuclear Iran - and I wouldn't be surprised if they actively cooperated with Israel in an attempt to prevent that.
I'm sure resisting the Nazis was against the US self interests, too, given all the lives, money and equipment it took. It would have been much easier to cut a deal with Hitler and keep on doing what you do, a thing which I have not the slightest of doubts you'd have strongly supported.
Likewise I suggest handing Taiwan over to the Chinese.
Overlooking the inherent lack of capability to distinguish "good" from "bad" you've so obviously demonstrated, consider the fact that without US backing, Israel would have long ago attacked Iran to stop this nuclear program. Diplomacy really takes a back seat when an assembly of extreme Muslims posses WMDs. Now, would THAT serve US interests?
You're sooo lame. Israel is too far away and too small a country to effectively deny the Iranians nukes, if they seek to acquire them. Attacking their facilities would absolutely guarantee that they'll create nukes.
And be sure to drag out the nazis, invoke the holocaust guilt trip, OK? Throw in a few other rightwing touchstones, like Taiwan while you're at it, do the usual false equivalency dance... Rave on about the evil Iranians, even as Israel keeps that relentless slow motion steamroller of middle eastern Liebensraum rolling over the Palestinians...
Poor Israel! Their grandparents were oppressed and murdered, so now they get to do anything they want! Well, just so long as they can make a show of "wanting" peace, even as they do everything possible to avoid making any reasonable compromise to achieve it...
Don't look at us, at what we're doing, look at the evil Iranians, or Hamas, or anybody but us! Nazis! Holocaust! Jew-haters! Baby killers and murderers!
It's wearing thin, and you know it, so you'll redouble your efforts to keep us convinced that you're oh so right and righteous, get that good old kneejerk reaction of guilt ridden acquiescence, of us going along with whatever you do, even though we know it's often monstrously wrong.
