What is the main leverage that Obama has, do we still give billions to Israel every year? If so, does Obama have any authority to cut off the aid? (I doubt it.) Unless there is something that Obama can do to punish Israel, Bibi should ignore him as the irrelevant Muzzie lover that he is.
It's more the diplomatic cover that the US gives Israel via the veto that comes with its permanent seat on the UN Security Council. Without that, the UN could impose economic sanctions a la Apartheid-era South Africa* and presumably cripple Israel's economy.
[*I am NOT calling Israel an Apartheid state. The dictators and Muslims at the UN hate Israel for existing; all else is pretext.]
