Why don't Jews have a country?

Jews once had a country, and their hometown was indeed Jerusalem. But after being ruled by the Roman Empire, they revolted because they could not bear the oppression of Rome. After the failure of the uprising, almost all Jews were expelled from their hometown, namely Israel and Palestine, by the Roman Empire. Since then, Jews have lived a life of wandering abroad. Because they were fired, they were scattered and did not form a force. They are scattered everywhere and can only be guests. It is normal for weak people to live in the land of other nationalities and be bullied, so they can only think more than other nationalities in order to survive. Since 2000, the whole nation has had to think of more ways to survive, so the evolution of IQ is inevitable. After screening in 2000, it is impossible to survive under oppression everywhere, and those who survive are elites.

Perhaps because of the living environment, the IQ of Jews has evolved the fastest in the past 2000 years. Because Jews and Arabs have the same roots, it is reasonable to believe that Jews and Arabs had the same wisdom before being expelled from the Roman Empire, but today, 2000 years later, their contributions to the world are far from each other.
