Civilians are being terrorised both in Gaza and in Israel. Obviously.

The only rational or moral justification for responding violently to violence is that it might serve to prevent and deter a violent response, otherwise it goes on for ever, as it has in the Holy Land throughout all our lifetimes. No sane person and no honest person can believe that there is any question of that kind of justification for the present use of violence by either side.

As the quote I gave puts it, "It's worse than a crime, it's a blunder."

We may rightly try to understand and explain what happens - but when we move on to support and encourage that blunder we share at least some symbolic responsibility for it.
