The Muslims attack, abuse and otherwise subjugate the Christians who live among them. The Christians live in fear and are abandoning their ancestral homes in droves. It seems to me that the Arab Christians would be natural allies of the Israelis. The problem is that the Christians who remain are scattered out all over the Middle East.
My suggestion is that if the Muslims in Gaza continue their attacks, the Israelis, after suitable warning, occupy Gaza, expel the Muslims and resettle the land with Arab Christians.
Of course the Israelis would suffer international censure but you would think that they would be used to that by now.
