Too late, the European Rabbinical Authority opens a conference on assimilation today. The assimilation rates cited by the rabbis closely echo Holocaust annihilation rates: 70 percent in Germany, 50–55 percent in most other European countries. Naturally, Jews who have abandoned their identity to the extent of settling in Germany are more prone to assimilation.
Unnoticed by the rabbis, the conference illustrates the cause of assimilation: the rabbis, by meeting in Paris, disregarded a clear commandment for every Jew to live in Eretz Yisrael. In this era of crumbling religious bonds, God has given Jews an antidote to assimilation—a state of our own. Those who refuse the antidote are not likely to survive as Jews.
The level of anti-semitism [Orthodoxy] in Israel, and the many thriving orthodox communities in the Diaspora, are clear indications that you are totally mistaken in thinking that the state of Israel is ‘the’ antidote to assimilation.
There’s a certain dislike of haredi communities, but religious Zionists are generally respected.
As for the Diaspora haredi communities, a lot of children leave them. It is basically the same process which occurred in East European shtetls a century ago.
