Don't blame Israel for this. Blame the numerous wealthy Arab states that surround Israel but are too cowardly to do anything about it. Iran and Saudi Arabia would rather destroy Muslims nations like Syria and Iraq then turn their attention towards the suffering of the Palestinian people.
Saudi Arabia is too busy plotting against Iran, and vice versa. Look at Egypt, it even closed its borders, they don't seem to care too much about the 'ummah', why should we take responsibility for this 'Ummah' when its guardians, the arabs themselves are happy butchering each other?
Saudi jewidia have spent hundreds billion dollars against Syria, Iraq ,Iran and Shia. But has not spent one dollar against israel. And no country in the world serve USA and Britian like saudis. What a shame!
