It's not known to me. And if there were tensions, the blame should probably be assigned equally. And what about Western Europe and Einstein?
The United States is a completely different situation. Jews have full citizenship here.

You: It's not known to me.
You ARE aware that, under the czar, Jews were severly restricted as to what part of the country they could live in, are you not? Do you call that citizenship?
In 1882, my father's grandfather was told that the town in which he had grown up would no longer be a place in which Jews were allowed. He made the wise decision to emigrate to the United States and never looked back.

Any American Jew who wins a Nobel Prize is rightly listed as an American, without question.
And I find it interesting that a Russia-Firster, such as yourself would question other people's loyalty to the United States.
