WASHINGTON -- When something happens for the first time in 1,871 years, it is worth noting. In A.D. 70, and again in 135, the Roman Empire brutally put down Jewish revolts in Judea, destroying Jerusalem, killing hundreds of thousands of Jews and sending hundreds of thousands more into slavery and exile. For nearly two millennia, the Jews wandered the world. And now, in 2006, for the first time since then, there are once again more Jews living in Israel -- the successor state to Judea -- than in any other place on earth.
Israel's Jewish population has just passed 5.6 million. America's Jewish population was about 5.5 million in 1990, dropped to about 5.2 million ten years later and is in a precipitous decline that, because of low fertility rates and high levels of assimilation, will cut that number in half by mid-century.
When 6 million European Jews were killed in the Holocaust, only two main centers of Jewish life remained: America and Israel. That binary star system remains today, but a tipping point has just been reached. With every year, as the Jewish population continues to rise in Israel and decline in America (and in the rest of the Diaspora), Israel increasingly becomes, as it was at the time of Jesus, the center of the Jewish world.
An epic restoration, and one of the most improbable. To take just one of the remarkable achievements of the return: Hebrew is the only ``dead'' language in recorded history to have been brought back to daily use as the living language of a nation. But there is a price and a danger to this transformation. It radically alters the prospects for Jewish survival.
For 2,000 years, Jews found protection in dispersion -- protection not for individual communities which were routinely persecuted and massacred, but protection for the Jewish people as a whole. Decimated here, they could survive there. They could be persecuted in Spain and find refuge in Constantinople. They could be massacred in the Rhineland during the Crusades or in the Ukraine during the Khmelnytsky Insurrection of 1648-49, and yet survive in the rest of Europe.
Hitler put an end to that illusion. He demonstrated that modern anti-Semitism married to modern technology -- railroads, disciplined bureaucracies, gas chambers that kill with industrial efficiency -- could take a scattered people and ``concentrate'' them for complete annihilation.
