Judea Pearl on why Obama's speech was unsettling...

He's the father of Daniel Pearl, the murdered journalist...

The first stems from crossed signals that are blocking the resumption of peace talks. Palestinians view Israeli settlement construction as the litmus test for Israel's intentions vis-à-vis a future Palestinian state. Israelis view Palestinian textbooks, TV programs and mosque sermons to be the litmus test of Palestinian intentions. A society that teaches its youngsters to negate its neighbor's legitimacy, so the argument goes, cannot be serious about respecting a peace accord as permanent.

Mr. Obama's speech, keenly recognizing the importance of emitting trust-building signals to break the stalemate, had crisp and stern words to say about Israeli settlements but hardly a word about Palestinian denial and incitement. "The United States does not accept the legitimacy of continued Israeli settlements," the president said. "It is time for these settlements to stop."

The hoped-for reciprocal sentence -- "It is time for Palestinian incitements to stop" -- was conspicuously absent. Commentaries on Israeli TV noted disappointedly that not a single demand was addressed to the Palestinian Authority.

This has left many Israelis wondering if the Obama administration is aware of the fierce, subterranean "battle of intentions" that has prevented the peace process from moving forward. In Israel, even the harshest opponent of the settlement movement would not support the emergence of a sovereign neighbor, rocket range away, that is unwilling to invest in education for a lasting peace.

A call for a simultaneous freeze on both Israeli settlements and Palestinian incitement, clad in timetables and monitoring methods, would have invited both sides to an equal honesty test. That test could help jump start the "new beginning" that Mr. Obama called for.

Secondly, Mr. Obama's rationale for Israel's legitimacy began with the Holocaust, not with the birthplace of Jewish history. "The aspiration for a Jewish homeland," he said, "is rooted in a tragic history that cannot be denied." Who else defines Israel's legitimacy that way? Iranian President Mahmoud Ahmadinejad does. Iran sees Israel as a foreign entity to the region, hastily created to sooth European guilt over the Holocaust. Israelis consider this distortion of history to be an assault on the core of their identity as a nation.

An affirmation of "Israel's historical right to exist," based on a 2,000-year continuous quest to rebuild a national homeland, is what the region needs to hear from Mr. Obama. The magic words "historical right" have the capacity to change the entire equation in the Middle East. They convey a genuine commitment to permanence, and can therefore invigorate the peace process with the openness and goodwill that it has been lacking thus far.
