To be fair they do have a lot of work to do keeping up the belief that Israel is America's strongest ally, despite all the spying, the vast sums of money sent the way of Israel*, the utter lack of any real assistance in any war that the US has been involved in, the abuse when the Israeli government doesnt get its way (ie Kerry's treatment lately, Obama's treatment generally), the vast lobbying on the Capitol in favour of a foriegn power, the inevitable transfer of technology to third states (whether deliberately or accidentally) and the massive diplomatic complications that come from giving the Israelis a blank cheque to do whatever they want, to whomever they want.
* admittedly much of it is spent buying US military goods, but its still taxpayers / borrowed money in the first place
