Israel—at least the largely secular and progressive version of Israel that once captured the world’s imagination—is over. Although that Israel was always in some ways a fantasy, the myth was at least grounded in reality. Today that reality has changed, and the country that has replaced it is profoundly different from the one its founders imagined almost 70 years ago. Since the last elections, in March 2015, a number of slow-moving trends have accelerated dramatically. Should they continue, they could soon render the country unrecognizable.
