Hamas’ brazen and vicious attacks within Israel have rightly drawn condemnation from around the world. If this is a war, as both sides agree it is, then Hamas’ deliberate targeting of civilians counts as a major war crime.

But the brutality demonstrated by Hamas did not emerge in a vacuum. The lesson of what is currently happening in Israel and Gaza is that violence breeds more violence.

The last real chance of avoiding the tragic conflict being waged between Israel and Hamas was destroyed by a single killing: the assassination of Israeli Prime Minister Yitzhak Rabin in 1995. The assassin was not a Palestinian militant, but an Israeli extremist opposed to the Oslo Accords, by which Rabin sought a “land for peace” deal that was anathema to Israeli radicals for whom Jewish sovereignty in the Holy Land is nonnegotiable.
