As allies, Israel and the United States should be so close together one could not slip a single sheet of paper between the two.
In the face of Iranian threats against Israel, that piece of paper should be reduced in thickness by a property of ten and still not fit between the nation of Israel and the United States.
Should we act on behalf of Israel? No. Israel is perfectly capable to act on their own and they have never once asked us to defend them, act for them or take the lead in their issues.
None the less, we should be there, with them, side by side never flinching, never blinking.
As things now stand, this is not the case.
Last week, in reported comments, Leon Panetta made that abundantly clear.
