How did you sleep on Thursday night? When I first learned that Israel’s war with Iran had begun in earnest, I, like so many of you, did not sleep much at all. Because of the 7-hour time difference between Boston and Israel, in the early hours of Friday morning I was able to reach Micah Goodman, our beloved teacher and friend who lives in Kfar Adumim, twenty minutes outside of Jerusalem. What Micah had to say was both inspiring and concerning at the same time.First the inspiring part. Micah shared that Israel’s attack on June 13 exceeded its wildest dreams. As Micah put it, the start of the war was all of Israel’s best military victories—the Six Day War, Entebbe, the destruction of Iraq’s nuclear reactor in Osirak in 1981, the exploding pagers that crippled Hezbollah—all at once. Using intelligence, covert operations, Mossad agents on the ground in Iran and drone technology, Israel was able to eliminate Iran’s leading generals and nuclear scientists in their homes, in their beds, in targeted attacks, in which Israel did not also kill their families. Why were Iran’s leading generals and nuclear scientists at home, in the first place? Why weren’t they in a bunker? Micah answers his own question by observing that we cannot prepare for something that has never before happened in history. What Israel accomplished on June 13 had never before been accomplished in the history of war, the kind of chutzpah, planning, skill and savvy that allowed these targeted assassinations. Add to that Israeli fighter jets that evaded Iranian air defenses, allowing Israel to attack more than 100 sites. Micah observed that Israel’s morale is very high.But there is a but. Micah and his wife and their teen-age daughters, like so many Israeli families, spent their night in a bunker. Shul throughout Israel has been cancelled. Micah’s public lectures for next week have been cancelled. All public events have been cancelled. Since the airport is closed, Israelis are worrying about food. Where will their food come from? Israel imports much of its food supply. He went to the grocery store on Friday morning, worried about whether his family will have enough food, and the store was jam-packed with nervous grocery shoppers, and the shelves were largely empty.So there is edge in Israel. Iran remains formidable. The Houthis remain formidable. There still is Hamas. There still is Hezbollah. While the beginning of the war could not have gone any better, where it will go next, nobody knows. There is what Micah calls “radical uncertainty” about what this war will mean for Israel’s future and for the region.What do we do with this complex picture? How do we understand and respond to it? What does it mean to us? What does it ask from us?
