While the Torah contains a commandment to “love your neighbor,” it has no equivalent of Jesus’ call to “love your enemies.” This difference, writes Ari Lamm, creates a very different Jewish answer to the question of whether it is moral to celebrate the recent demise of the head of Islamic State. Citing a sermon given by his grandfather, Rabbi Norman Lamm, in 1973, he clarifies Jewish position:

First, there are some ideas, movements, or even people who are so profoundly, unusually evil that hatred is not only justified but required. All decent people should feel hatred for a Haman, or a Hitler, and no contextualizing or relativizing will exempt us from this basic requirement. There is nothing that we can learn about Stalin’s background, or Pol Pot’s childhood, that can earn them our love and forgiveness.

By the same token, Jewish tradition has also understood hatred’s wildly destructive potential. It has thus sought deliberately to circumscribe it as much as possible, reserving it only for those singularly evil individuals who unquestionably deserve it. As [the elder] Lamm concluded, “We must live our lives so that the commandment of hatred becomes the most difficult of all to observe. And by restricting our hatred to evil and those who personify it . . . we shall learn to act lovingly to all God’s creatures.”

So, may we hate Abu Bakr al-Baghdadi? . . . [N]ot only may we; we must. In [Lamm’s] words, “monsters who seek sadistically to wipe out whole populations—such people remain deserving, on purely moral grounds, of actual contempt and hatred.”

Israel will likely respond directly against Iran after yesterday’s attack, and has made known that it will calibrate its retaliation based not on the extent of the damage, but on the scale of the attack. The specifics are anyone’s guess, but Edward Luttwak has a suggestion, put forth in an article published just hours before the missile barrage: cut off Tehran’s ability to send money and arms to Shiite Arab militias.

In practice, most of this cash comes from a single source: oil. . . . In other words, the flow of dollars that sustains Israel’s enemies, and which has caused so much trouble to Western interests from the Syrian desert to the Red Sea, emanates almost entirely from the oil loaded onto tankers at the export terminal on Khark Island, a speck of land about 25 kilometers off Iran’s southern coast. Benjamin Netanyahu warned in his recent speech to the UN General Assembly that Israel’s “long arm” can reach them too. Indeed, Khark’s location in the Persian Gulf is relatively close. At 1,516 kilometers from Israel’s main airbase, it’s far closer than the Houthis’ main oil import terminal at Hodeida in Yemen—a place that was destroyed by Israeli jets in July, and attacked again [on Sunday].
