Mr. Limon, I read your other comment and disagree with your characterization of Einstein's reply as the demonstration of "immense pride".

How you can interpret Einstein's use of the word "precarious" and its context as "immense pride" baffles me. Precarious means, "not securely held or in position; dangerously likely to fall or collapse, dependent on chance; uncertain.

Einstein expressed his concerns very clearly in the letter you cited and I quote... "I am the more distressed over these circumstances because my relationship to the Jewish people has become my strongest human bond, ever since I became fully aware of our precarious situation among the nations of the world."

There is nothing prideful in that letter. Instead, those are the words of a man who fully understands the dangers he is personally facing as a member of a people who are in danger in every country on earth (including the United States). Instead of pride, Einstein was a realist coping with real fears.
