Israel is under real existential threat. The modern state exists because a portion of modern Jewry was not only under existential threat, but actually found itself decimated. This is incontrovertible. Not again, never again.
But existential threat offers possibilities and opportunities. You can engage in deep, serious, measured and open consideration of exactly what that means and how to respond. Or you can treat is a license to do anything, and to reject and attack all those—even Jews—who suggest you can’t necessarily do anything. Giving a moral inch is giving a moral mile, and it is a slippery slope. This is currently Israel’s posture.
This is precisely the position of the National Rifle Association regarding guns and the Second Amendment. It is all or nothing. Even a hint that the Second Amendment might be conditional is dangerous. The next thing you know, “they” will be coming around to take your guns. That can’t be allowed to happen, no matter how many people are killed or injured, how many innocent lives ruined, in the meantime.
Sorting through values is hard work, and the conclusions can be inconvenient and costly. Easier to deal with absolutes. That way, you can sleep righteously and soundly, without worrying about the victims of your carelessness.
