Let's get on solid ground with that, cut down on the emotions, yeah?

- Israel and the US were not allies at the time of the USS Liberty incident. There were a friendly relationship and a Cold War going on, but Israel was not expected to mind US interests at the time.
- There's no rational basis to the hostility of Iran towards Israel other than the Mullah's eagerness to talk the Arabs' talk (hatred), and to walk their walk (jihad) in order to make them amenable to their imperial plans. So far, this is working, although there still is a widespread wariness, among Sunni Arabs, of the said plans, which clueless US policymakers read as the "atavistic Arab-Persian -or Sunni-Shi'ia- hostility" that exists only in their ignorant and gullible minds.
.- Likewise, there was no rational basis either to Hamman the Wicked's plan to exterminate the Jews of the 5^th century BCE Persian Empire. According to the Book, he and 70,000 of his supporters died trying. Go figure!
- Israel's strategic interest is getting Iran back on its side as a major trade partner in its area. All this would take is a regime change, since most Iranians would like this to happen too. US (Condi's) policy is to attempt to build an Arab-Israeli axis against Iran none of the protagonists finds doable or even palatable (see above). This is already failing, bigtime.
- The Mullahs with nukes and the means to deliver them (which there's no doubt they already have) will have the means to remain in power forever.
- The Mullahs in power and engaged in a protracted, static shooting war against foreign nations will have the means to remain in power forever. Iranians are as patriotic as we are, perhaps even a little more, and the Mullahs will engineer the war need against a foe that cannot defeat them, if they feel nothing else will keep them in power. It has worked for them previously: if they engage Israel while the US sits on the fence, they risk very little as only their Syro-Hizbullah proxies will do the dying for them.
- The only way tiny Israel can hit Iran's huge nuclear effort is not by conventional means, if I am to believe the poorly substantiated rumor that my country has nuclear weapons, and not only the much cheaper reputation of having them. Notwithstanding the enormous risks, doing this goes against Israel's strategic interest, see above.
- The only way to prevent the Mullahs having nukes and a free hand to do much, much evil is a concentrated, decisive and swift conventional strike on the regime, its IRGC goons, and their weapons infrastructure, sparing as many Iranian Army troops and civilian infrastructure as possible. Only the US has the means to do that and to save countless lives, mostly of Iranians! It worked for Serbia, where America had much less at stake than in the ME.
- Now we know that America won't do it. Too bad.
- The United States of America's founding fathers cautioned against foreign alliances. Americans remember this, and may vote accordingly.
- The US aid to Israel, with its many strings attached, is increasingly viewed, by Israelis, as a hindrance to development and an unacceptable breach of sovereignty. Refusing it, however, would necessitate putting the entire Israeli economy on a war footing, something that nobody wanting to be elected would do at present.
- The US taxpayers money sent away to Israel as military aid invariably ends up in the pockets of US weapons manufacturers, and as American workers' salaries as well.
- The Israeli arms manufacturers are therefore kept on a kosher, no-pork diet, and this apparently keeps them lean and competitive, and thriving.
- For some Americans, the price of gasoline is more important than America's role as a superpower.
- Many Americans object their country being a superpower. They always have, and always will.
- Americans holding both of the above views would very easily uncork Alaska and withdraw (in disgust) from this whole unsavory ME business. Israelis should not have any difficulty understanding and even identifying with this.

Yelli, my usually level-headed scientist friend at Ben-Gurion U is lyrically enthusiastic about what's being done next door with water manufacturing and renewable energies. Yet, she's not the least Ashkenazia, and nobody in the Israeli R&D community even cares about who is and who isn't Ashkenazi!
Also, technological advancement nowadays is international in essence, and there's no political gold mine in it for anybody in particular.

"- The only way tiny Israel can hit Iran's huge nuclear effort is not by conventional means, if I am to believe the poorly substantiated rumor that my country has nuclear weapons, and not only the much cheaper reputation of having them."

Does this help substantiate the "rumor"?
