It’s not that they fear the United States per se, but rather that they have a significant self-interest in keeping strong US ties. Israel has no qualms in attacking Iran, but if the US does not endorse the attack then it will become a diplomatic risk. You can see evidence of this with Israel trying to strengthen its relations with other countries to hedge against such a risk. The Israeli and US partnership is inestimable and it would be inexcusable for Obama to use it as leverage.
If push comes to shove... Israel will unilaterally attack Iran. Of course, this is how I see it.
Yeah, except he already has. Also previous presidents have mistreated Israel. Bush 43 failed repeatedly to undertake joint action against Iran. Clintoon financed the "make Arafat a billionaire" program. Bush 41 sold the "ignore Iraqi SCUDS while I kiss Bedouin butt" program, and even Reagan had the Iran "kill anyone you want, I can't do squat because you released the Embassy Hostages" policy.
Israel has seen this for years, and it gets progressively worse. Why would they think we would improve without being threatened?
Russia's Georgia operation was simply the reversal of US policy in Eastern Europe by order of Vladimir Putin. Zer0 promptly gave up the anti ballistic missile deployment for EE when THREATNED. Seems to me Israel should just tell Zer0 what he's gonna do, everybody else does.
If push comes to shove... Israel will unilaterally attack Iran.
I certainly hope so, but why beat down settlers in the meantime? Just because Zer0 asks? He's going to keep his record as a total fail on interfering with America's enemies, and if Israel WILL whack Iran and Zer0 interferes, the price of interference is the destruction of the oil fields and port in addition to the nuke bunkers, which will severely affect the US and European economies at the minimum.
Israel holds a lot of cards, if Zer0 call their bluff, he would find it wasn't.
