A CBS "60 Minutes" report on the status of Christians in the West Bank that aired on April 22nd.
Let me stipulate a point made by Micahel Oren: It is true that, relative to many other places in the Middle East today, Christians in the West Bank have it pretty good, and Israeli Christians somewhat better. But the point is that this status is relative. Christians in Israel (at least those of Palestinian descent*) and the Occupied territories suffer enormous hardship and oppression by virtue of being Palestinian. But while Michael Oren may have an argument that those who are concerned for the treatment of Palestinian Christians ought to speak out just as vocally about the persecution of Christians in other parts of the Middle East it is worth noting that a) very often, they do; and b) failing to speak out in one case does not render it invalid to speak out in another; and c) unlike Israel, these other countries are not the largest single recipient of U.S. foreign aid.
Oren makes an incredibly callous statement about midway through the piece when he says that he regrets the inconvenience caused to Palestinian Christians by the wall, but then goes on to say: "It's their convienience, but it's our survival." While the wall has certainly cut down on terrorism, there's no question about that, there's no reason to believe that it is, on its own, a necessary instrument of Israeli survival, particularly given that there's no reason to believe that acts of terrorism are, in themselves, a threat to Israel's existence.
Finally, it's worth noting that the single most effective means of diminishing terrorism in any situation that is sustained by occupation is to abandon the occupation, reach a just settlement of the dispute and aid in materially improving the lives of those who live there.
*During my last visit to Israel, it was pointed out to me that the fastest growing segment of Israeli Christians is actually not among the Palestinians but among the Chrisitans spouses of Jewish emigrees from Eastern Europe and Russia.
