There comes a time when one (Israel) stops appeasing else it gets out of hand.
Israel will be sunk in no time flat if the USA pulls away it’s protection from the UN Security Council Resolutions, and other UN Agency agreements and resolutions.
That won’t make a bit of difference to the USA in terms of affecting it negatively, but it will DESTROY Israel, and Israel knows that. Israel just needs to do whatever it takes to keep things on an even-keel until Obama is out of office!
