Returning from exile in the 5th century BCE, Jews brought with them the Babylonian names for the months and the Babylonian calendar itself. As Sacha Stern writes, it suited them:

The Babylonian calendar originated in Babylonia (southern Iraq) in the early second millennium BCE, spread to the rest of Mesopotamia in the late second millennium BCE, and then became, in the first millennium BCE, the official calendar of the great empires of Assyria, Babylonia, and Persia, in use across the whole Near East. The Jews under Persian rule adopted it as their own calendar, as did many other peoples in the Persian empire.

The Jews adopted not only Babylonian month names but also the entire Babylonian calendar. This calendar was lunar, with each month beginning at the sight of a new moon. Since twelve lunar months are approximately eleven days shorter than the solar year, the Babylonian calendar was intercalated (or evened out) every two or three years by the addition of a thirteenth month (usually by duplicating the twelfth month, Adar, and less frequently by duplicating the sixth month, Elul). This allowed the lunar system to catch up with the sun and the seasons. This calendar may have been quite similar to the original Israelite one, which was most likely also lunar; indeed, this may have helped the Jews to adopt it without qualms. . . .

[A]fter the Jewish Hasmonean state broke off from its Hellenistic Seleucid overlords in the mid-2nd century BCE, the Jews no longer had any reason to comply with the calendar of distant Babylon, and their calendar soon acquired distinct features.

For some time, opponents of U.S support for Israel have been urging the White House to end the war in Gaza, or simply calling for a ceasefire. Douglas Feith and Lewis Libby consider what such a result would actually entail:

Ending the war immediately would allow Hamas to survive and retain military and governing power. Leaving it in the area containing the Sinai-Gaza smuggling routes would ensure that Hamas can rearm. This is why Hamas leaders now plead for a ceasefire. A ceasefire will provide some relief for Gazans today, but a prolonged ceasefire will preserve Hamas’s bloody oppression of Gaza and make future wars with Israel inevitable.

For most Gazans, even when there is no hot war, Hamas’s dictatorship is a nightmarish tyranny. Hamas rule features the torture and murder of regime opponents, official corruption, extremist indoctrination of children, and misery for the population in general. Hamas diverts foreign aid and other resources from proper uses; instead of improving life for the mass of the people, it uses the funds to fight against Palestinians and Israelis.

Moreover, a Hamas-affiliated website warned Gazans last month against cooperating with Israel in securing and delivering the truckloads of aid flowing into the Strip. It promised to deal with those who do with “an iron fist.” In other words, if Hamas remains in power, it will begin torturing, imprisoning, or murdering those it deems collaborators the moment the war ends. Thereafter, Hamas will begin planning its next attack on Israel:

Hamas’s goals are to overshadow the Palestinian Authority, win control of the West Bank, and establish Hamas leadership over the Palestinian revolution. Hamas’s ultimate aim is to spark a regional war to obliterate Israel and, as Hamas leaders steadfastly maintain, fulfill a Quranic vision of killing all Jews.

Hamas planned for corpses of Palestinian babies and mothers to serve as the mainspring of its October 7 war plan. Hamas calculated it could survive a war against a superior Israeli force and energize enemies of Israel around the world. The key to both aims was arranging for grievous Palestinian civilian losses. . . . That element of Hamas’s war plan is working impressively.
