It is known that the Norman king was the illegitimate son of the previous duke of Normandy and a woman name Herleva, whose father was a tanner. Joshua Gelernter examines some circumstantial evidence that she might have been Jewish:

According to the 19th-century historian Edward Freeman, William the Conqueror, who was also known as William the Bastard, was sometimes known as “William the Mamzer.” This is where things get interesting. Mamzer is a Hebrew pejorative meaning the child of an illegitimate sexual relationship, such as adultery or incest. In Europe, it may have entered the vernacular as a pejorative for the offspring of a particular type of illegitimate relationship—one between a Christian man and a Jewish woman. . . . [Furthermore], in medieval Europe, tanners were frequently Jews. . . .

We know that in the 11th century Normandy was home to a large number of Jews. By some estimates, its capital Rouen began that century with a population that was one-fifth Jewish. And we know that William was relatively fond of the Jews: after his Conquest, he suggested Normandy’s children of Israel resettle in England—a surprising invitation, even for someone interested in developing trade and finance. . . .

Does any of this prove that England as we know it was founded by a Jew? Of course not. But it’s something to chew on.

Early Friday morning, Israel attacked military installations near the Iranian cities of Isfahan and nearby Natanz, the latter being one of the hubs of the country’s nuclear program. Jerusalem is not taking credit for the attack, and none of the details are too certain, but it seems that the attack involved multiple drones, likely launched from within Iran, as well as one or more missiles fired from Syrian or Iraqi airspace. Strikes on Syrian radar systems shortly beforehand probably helped make the attack possible, and there were reportedly strikes on Iraq as well.

Iran itself is downplaying the attack, but the S-300 air-defense batteries in Isfahan appear to have been destroyed or damaged. This is a sophisticated Russian-made system positioned to protect the Natanz nuclear installation. In other words, Israel has demonstrated that Iran’s best technology can’t protect the country’s skies from the IDF. As Yossi Kuperwasser puts it, the attack, combined with the response to the assault on April 13,

clarified to the Iranians that whereas we [Israelis] are not as vulnerable as they thought, they are more vulnerable than they thought. They have difficulty hitting us, but we have no difficulty hitting them.

Nobody knows exactly how the operation was carried out. . . . It is good that a question mark hovers over . . . what exactly Israel did. Let’s keep them wondering. It is good for deniability and good for keeping the enemy uncertain.

The fact that we chose targets that were in the vicinity of a major nuclear facility but were linked to the Iranian missile and air forces was a good message. It communicated that we can reach other targets as well but, as we don’t want escalation, we chose targets nearby that were involved in the attack against Israel. I think it sends the message that if we want to, we can send a stronger message. Israel is not seeking escalation at the moment.
