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.

Unlike his past many predecessors, President Joe Biden does not have a plan for solving the Israel-Palestinian conflict. Moreover, his administration has indicated its skepticism about renewing the 2015 nuclear deal with Iran. John Bolton nevertheless believes that there could be a collision between the new Benjamin Netanyahu-led Israeli government and the Biden White House:

In possibly his last term, Netanyahu’s top national-security priority will be ending, not simply managing, Iran’s threat. This is infinitely distant from Biden’s Iran policy, which venerates Barrack Obama’s inaugural address: “we will extend a hand if you are willing to unclench your fist.”

Tehran’s fist is today otherwise occupied, pummeling its own people. Still, it will continue menacing Israel and America unless and until the internal resistance finds ways to fracture the senior levels of Iran’s regular military and the Revolutionary Guards. Netanyahu undoubtedly sees Iran’s growing domestic turmoil as an opportunity for regime change, which Israel and others can facilitate. Simultaneously, Jerusalem can be preparing its military and intelligence services to attack Tehran’s nuclear program, something the White House simply refuses to contemplate seriously. Biden’s obsession with reviving the disastrous 2015 nuclear deal utterly blinds the White House to the potential for a more significant victory.

To make matters worse, Biden has just created a Washington-based position at the State Department, a “special representative for Palestinian affairs,” that has already drawn criticism in Israel both for the new position itself and for the person named to fill it. Advocated as one more step toward “upgrading” U.S. relations with the Palestinian Authority, the new position looks nearly certain to become the locus not of advancing American interests regarding the failed Authority, but of advancing the Authority’s interests within the Biden administration.
