The correct answer to this open question is the following.
The reason why Jews live as minorities in many lands for almost two thousand years was because of the many diasporas since ancient Egypt times. Let's remember that Jews had no land to live in. Indeed it was Moses who took them out form Egypt and led the Jewish people throughout the desert for 40 years. This information is according to the Exodus Book of the Old Testament, in the Bible. They were looking for the Promise Land and that is why they got to Jerusalem. Since those years, Jewish people had lived as minorities in many lands for almost two thousand years until they established the state of Israel on May 14, 1948, in Tel Aviv, with the support of Great Britain and the United States.
