I'm not saying Obama is anti-Israel, anti-Zionist or anti-Semitic or that Hillary will be any of those things either, but it makes sense for Israel to understand that Big Daddy America clearly isn't a 100% reliable ally and produce more sh**t at home..
This hardly anything but just unsubstantial noise. The problem between Israel and the current US administration is the lack of decisiveness of the latter against the fait accompli policy executed by the Israel government on the key issue of the settlements, as well a generic lack of guts in order to push for a solution of the conflict. The US government is clearly biased towards Israel and tends to forgive or justify the questionable, to say the least, actions of his ally, which tends to abuse of the trust of "Big Daddy". Claiming otherwise sounds weird, honestly. Especially when Hilary is notoriously pro Israel and is not a serious threat for your beloved Bibi.
