Enemies of Israel have characterized the Balfour Declaration—the centenary of which is tomorrow—as “one nation’s promise to another of the land of a third.” Less hostile observers have pointed to the woe caused by Britain’s later abrogation of it. Dore Gold explains why it still matters:

The Balfour Declaration is important because it recognizes the historical bond of the Jewish people to the Holy Land, a bond which existed long before the declaration. What was significant was its public and formal recognition and its incorporation into international law. . . .

The Balfour Declaration is a tremendously important document because it contains world recognition of the historical rights of the Jewish people to a national home. . . Thus, the [League of Nations’ Palestine] Mandate and the Balfour Declaration, upon which the Mandate was based, did not create Jewish historical rights, but rather recognized a pre-existing right.

The Jewish claim to the Holy Land is based on facts, as we may understand from Chaim Weizmann’s language and choice of words when he explained that it was a major historical event. He called the Balfour Declaration an “act of restitution” and emphatically described it as a “unique act of the world’s moral conscience.” Expressing his deep awareness of historical continuity over millennia, he called it “the righting of a historical wrong” and an “act of justice.” . . .

[Precisely for this reason], the tendency to justify Zionism on the basis of the Holocaust is totally misconceived.

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.
