It'll be interesting to see how much Israel keeps up their posturing and stick-poking as the US becomes increasingly unwilling to remain their lap dog.
The US also objected to the strikes on the Iraqi and Syrian reactors. Israel decided to go ahead anyway. While in the Syrian case the US gave some sort of approval by turning its back and looking the other way, in the Iraqi case Israel was publicly condemned by the US. It seems like the usual US policy is that as long as it is not killing Americans right now, or god forbids threatens American economic interests, the best course of action is to stick their heads in the sand. The ironic thing is that this policy actually worked in the Iraqi and Syrian cases mentioned above, since while the heads were in the sand, Israel defused the situation.
The Iranian case is significantly more difficult than the above two, otherwise Israel would have already struck and accept the condemnations. Does the US have a spare carrier it can "lend" to Israel for a couple of weeks? Then again "lending" may be too active. The US can just leave the carrier parked in the east Mediterranean near Haifa bay with the keys in the ignition. Then report it was stolen and add "theft" to the post-strike condemnation.
edit:
Forgot about N-Korea. Unfortunately, Korea is way too far from Israel, so in that case the head in the sand strategy did not work. I guess you win some, you lose some.
