Islamic countries would see it as an annexation (so still not recognise jewish Israeli citizens) and the amount of cash generated for new mosques and islamic schools within Israel would be unprecedented. Inheriting the westbank means inheriting debt and problems too. Immigration will be stopped after a while which will favour muslim demographics. Look at demographics of SE Asia and Europe to see how fast Islam spreads. Likud thinks it annexes, but in fact it will absorb itself into something giant. The jews who make the economy will hate the sound of the mosques and the new dress codes on the beach and will leave. <30% and control and laws slip away (also under internat pressure: democratic rights, etc). I don't care about judaism myself, but loss of equal rights and democracy can happen quickly. Really, the demographics-responses here are correct, have a look in big European cities. Laws are more dynamic than anchors.
