Why the Modern Sukkah Needs Wireless Internet

Oct. 14 2022

“Dwell in booths [Hebrew, sukkot] seven days; all that are Israelites born shall dwell in booths.” The Talmud understands this commandment as requiring that one eat and conduct everyday activities in this hut-like structure. Gil Student explores a modern-day implication of this requirement:

A sukkah needs to be usable. Rabbi Moses Isserles (16th-century Poland) writes that a sukkah in which you cannot do certain basic things is an invalid sukkah. . . . According to Isserles, [then], does a sukkah today need WiFi?

I ask this because many people cannot take vacation from work for all of Sukkot. They have to work on some or all of ḥol ha-mo’ed [the last six days of the holiday, during which work and other activities are permitted]. However, particularly since the changes to work habits caused by COVID-19, many people will work from home during Sukkot. Do they need to work in their sukkah? If they do, they probably need WiFi in their sukkah so they can work. If so, a lack of WiFi might raise questions about the validity of the sukkah of someone who needs to work.

Therefore, it would seem that if you have to work from home, you should set up a workstation in your sukkah. If that requires WiFi, then you should make sure your WiFi extends to your sukkah and use it only for things that are permissible in a sukkah. It might even be true that according to Isserles, your sukkah is invalid if you cannot work inside it. . . . However, according to the Mishnah Berurah, [a highly regarded early-20th-century halakhic compendium], even though you should be able to work from your sukkah, if you for whatever reason you cannot, your sukkah is still kosher.

Israel Had No Choice but to Strike Iran

June 16 2025

While I’ve seen much speculation—some reasonable and well informed, some quite the opposite—about why Jerusalem chose Friday morning to begin its campaign against Iran, the most obvious explanation seems to be the most convincing. First, 60 days had passed since President Trump warned that Tehran had 60 days to reach an agreement with the U.S. over its nuclear program. Second, Israeli intelligence was convinced that Iran was too close to developing nuclear weapons to delay military action any longer. Edward Luttwak explains why Israel was wise to attack:

Iran was adding more and more centrifuges in increasingly vast facilities at enormous expense, which made no sense at all if the aim was to generate energy. . . . It might be hoped that Israel’s own nuclear weapons could deter an Iranian nuclear attack against its own territory. But a nuclear Iran would dominate the entire Middle East, including Egypt, Jordan, the United Arab Emirates, and Bahrain, with which Israel has full diplomatic relations, as well as Saudi Arabia with which Israel hopes to have full relations in the near future.

Luttwak also considers the military feats the IDF and Mossad have accomplished in the past few days:

To reach all [its] targets, Israel had to deal with the range-payload problem that its air force first overcame in 1967, when it destroyed the air forces of three Arab states in a single day. . . . This time, too, impossible solutions were found for the range problem, including the use of 65-year-old airliners converted into tankers (Boeing is years later in delivering its own). To be able to use its short-range F-16s, Israel developed the “Rampage” air-launched missile, which flies upward on a ballistic trajectory, gaining range by gliding down to the target. That should make accuracy impossible—but once again, Israeli developers overcame the odds.
