JERUSALEM — Israeli politics is not subtle. Threats are always existential, opponents are out to destroy everything voters hold dear, and the enemies aiming rockets at residential neighborhoods from the Galilee to the Gaza periphery can seem only scarcely more menacing than the supposed enemies within.

With Prime Minister Benjamin Netanyahu polling neck and neck against Benny Gantz, a former army chief, riling up the base is as important as persuading anyone still on the fence. Right-wing parties talk tough about terrorists and liberal jurists; left-wing parties vie to sound like the most authentic peace-loving progressives; and centrists try to show that the parties to the left and right of them are unreasonable.

Just take a look at the commercials targeting voters on social media as the election next Tuesday draws near. They are in Hebrew and Arabic, but much of what is shown in the ads requires little or no translation. Let’s move from the political right to the left.
