Answer: There is a purely psychological effect: When a person lives in a certain environment, he wishes to justify his existence in it. But if he has an additional environment, that means he is not entirely loyal to the one in which he exists, and therefore the environment perceives him as “not one of us.”
For example, this is apparent from people’s reaction to the Pollard case, and from my contact with many American Jews. They are very critical of Israel because it would be more comfortable for them if it were different, more attractive to Americans. The prevailing opinion among them is, “Israel is not acting right!” Not to mention their love and support of Obama…. And what about his Jewish advisers, who are bothered by Israel’s very existence in the context of their global plans….
Generally speaking, I suggest you look at history, at how America closed itself off to emigration of European Jews, indirectly sending them to the gas chambers. Yet President Roosevelt was known as ‘President Rosenfeld’ because of the great number of Jews in his administration, and Bernard Baruch, Roosevelt’s financier and adviser, was known as the ‘unofficial president.’
A while ago there was a documentary film about the history of television, called “The President of the Jews” which showed a full blown conflict between Bernard Baruch, the State Department, and Jews in the Treasury Department and the courts. Finally, the State Department created additional bureaucratic obstacles, such as a requirement to present a certificate of good behavior from the German police.
