Jews live amongst the nations, yet they insist on separating themselves from the foreigners. Jews are loyal to the nations--upholding the laws of many peoples, serving in the armies and governments of many lands, working for the betterment of many nationalities, adopting the customs and culture of the gentiles, and celebrating the many foreign holidays--yet they think of themselves as a different people. Judaism is not very different from the other religions, yet they insist upon remaining Jewish, even dying for this cause. And the Jews are largely confused and misguided, saying Israel is only a religion, yet they think of themselves as the Chosen nation. Until the Jews understand who they are, where they belong, and Whose Laws they must follow, they will remain a foolish people; a disgrace to themselves, a ridicule of their Purpose, and a mockery of their G-d. Until the Jews understand that they are Israel, and Israel is where they belong, the Jewish people will remain hypocrites and they'll continue to disgrace their name and disdain the Name of G-d.
Israel cannot be a Jewish country, nor can it be a secular land. Israel cannot have democracy, and its laws cannot be the laws of man. Israel cannot be the home of the nations, nor can it be ruled by foreigners. Israel cannot be the diaspora, nor can its people live in "exile" in their own Land. If Israel assimilates and becomes like the nations, then there will be no Israel and the mistakes of the past will be repeated. And this is not merely an issue of the people of Israel, both those in Israel and those who live in delusion; it is an issue of all humanity. If Israel dissolves into thoughts, then people will think whatever they want. And if even Israel mocks its G-d, the Holy One of Israel, then who would know G-d and who would accept His Laws? If Israel assimilates with the Jews, like in exile, then progress will have been a thing of the past. You might say the world doesn't need Israel and people don't need G-d or His Laws, but if you observe history then you'll know how it was, and if you look out your window, then you'll know what could come.
Jews are foolish people. Visit any place in the world and you'll find some Jews wandering around thinking it is their home. The Jews are confused and lost. They are scattered about and mixed up in thoughts. Jews swear their loyalty to nearly every nation, thus the nation of Jews is a betrayal of every nation. And Jews insist they belong in exile, and they assimilate in every land, serving every nationality but their own. Still, Jews are "against" assimilation and they decry conformity, conversion, and marriage with a gentile.
I'm not bothered by assimilation, as long as the Jews remain the way they are. If the Jews don't change, it's clear that they will assimilate, because they are already removed from G-d. If such is their decision, then such will be the results, but if the Jews in exile care about Israel, then they'll start to care about themselves. The issue is no longer that of Jewish assimilation; the Jews are only a shadow in the body of Israel. However, when Israel assimilates, it brings destruction to itself.
