The Islamic State has invited Muslims from everywhere in the world to come and live in it.

This presents a golden opportunity for Palestinians to be assimilated at last by their own people. Arabs among Arabs. They can be citizens of the new Caliphate.

Israel should encourage the transfer of willing West Bank Arabs and Gazans to the new Islamic State.

Of course it is likely that most Israeli Arabs citizens will prefer to stay in Israel. They are not on the whole a problem to themselves or anyone else. Israel has never aimed at becoming an Arab-free country (though it has been accused of wanting to be just that by its enemies, especially Leftist Israeli historians), and it would be the poorer if it were.

But the Gazans who voted for Hamas to govern them – it will be just like home for them to be under the rule of ISIS/ISIL. And the stone-throwing youth of the West Bank – they’ll be given real weapons by the Islamic State.

Who will not have what they want? Only those Arab states that want to use the Palestinians as a perpetual reproach to Israel and the Western powers who allowed Israel to come into existence.

The loss of that use of them might irritate Obama too, but he could console himself that ISIS is Islam Victorious.
