Answer: I do not think this is going to happen. When the Jews in France wanted to leave (there were half a million of them there) the newspapers wrote that France could be shut down. Meaning, their participation in the management of industry, science, and art is such that nothing would remain of France. I do not know to what extent this is true. I am not connected with it, but this is what happened.
In addition, throughout history we have seen such examples that when Jews left countries, the countries declined.
