There aren't a lot of defined minority groups that have managed to maintain their existence for millennia. In the West, I can think of but two, the Jews and the Roma (along with a few Christian sects like the Amish). Of course, there are still pockets of such people around, particularly in the Middle East, and a long history of such groups that no longer exist, either through assimilation or violence. The Catholic Church has been particularly careful to eliminate its rivals over the centuries (which is why there isn't an Albigensian Lobby!).
It is tough to keep a defined minority together. Other than the violence (which requires an investigation of the methods used by the group to establish relations with the outside, the subject of another posting, which will lead to a consideration of the relative success of the Jews and the Roma), the main problem is preventing voluntary assimilation. Being different is uncomfortable. Everybody wants to belong to the larger society. The different rules of the larger society look like freedom to younger people. How do you prevent assimilation?
The main method used by all minority groups to prevent assimilation is a mythology of the vast superiority of the group over the outsiders. This is drilled into children from the youngest age (I should note that this brainwashing is the main reason why almost all Jews are hopelessly confused on issues of the Middle East, and why the Jews won't be able to solve the problem they have created). People gain a considerable amount of their self-worth from their perceived superiority as members of the group. Preservation of the superior group is the highest value, and damaging the group is the greatest sin.
Of course, 'marrying out' is a terrible wrong. In a group where belonging is defined through the mother, 'marrying out' for a man is the greatest possible sin. Not only is it a sin in itself as it damages the group, but it dooms the children to a half-life as animals who can never regain their lost superiority. The conversion required of outsiders who 'marry in', and the controversy which still surrounds such conversions, is evidence of the importance of the perception of race purity in group identity.
It is not a coincidence that the Jewish Billionaires are all middle aged men, many of them who have themselves committed the ultimate sin or who have seen it among their colleagues. They are obsessed with assimilation. Contrary to what you might think, they are not obsessed with the physical survival of Jewish people; they are obsessed with the racial purity of the group. Since the Jews have no real defined racial characteristics - most Jews are racially identical to the Palestinians, and almost all of the Jewish Billionaires are descended from relatively late converts who have never had any connection with the Middle East - this is largely bullshit, but bullshit that is the subject of rather fervent belief.
We can only understand the mystery of the Israeli Empire - Greater Israel - if we grasp the central importance of this fear of assimilation. Obviously, the manipulation of the United States to fight Wars For The Jews, and the manipulation of Middle East politics to create a series of wars around and involving Israel, is very risky to the existence of individual Jews. The Jewish Billionaires don't care about that. Israel, or Greater Israel, is Anti-Assimilation-Land. Since everybody around you is a Jew, and, as planned, no Jews will be elsewhere, there is no risk of 'marrying out'. The guiding perception is that the key threat to the Jewish people isn't a holocaust, it is the gradual drifting away of members of the group. The Jewish Billionaires are willing to take any risk and commit any atrocity - start wars, kill and displace millions of people, end human civilization, destroy human rights and free speech around the world, destroy international law. and lay low the greatest economies, all to avoid the risk of the greatest threat to the Jewish group, assimilation.
Of course, the paradox is that the more evil the Jewish Billionaires act, the more that decent and moral Jews are voting with their feet and voluntarily leaving the group, fed up with all the violence and lies and manipulation. This drives those who remain even crazier, and makes them take even greater risks.
The ultimate goal of the Jewish Billionaires is to make Israel 'racially' pure, and have all the Jews of the world living in Israel. This explains the odd behavior of Israel. Why is Israel always obsessed with its short borders, and how difficult such borders are to defend? Surely short borders are easier to defend than the borders of a country stretching from the Nile to the Euphrates. The reason that Israel has never set its borders is that the calculations are that the Jews, after all moving to the Middle East and being fruitful and multiplying, will need all the land of Greater Israel in order to be able to survive.
Self-worth is defined by group identity, but the group is threatened by assimilation. The only way to stop assimilation is to move all the Jews to one place, Anti-Assimilation-Land, and that place is Greater Israel. That is the explanation for the irrational behavior of the Jewish Billionaires, and the irrational out-of-control violence of the Jewish State.
