It isn't very well known that Albert Einstein also became a strong supporter of the
Zionist movement.
This support for the Jewish people, himself one, probably played a hand in his recommendation that the USA build a thermonuclear device to counter the possibility that Germany already might have had one.
The Israelis, whose country is believed to be the sacred land of the Jewish people offered Albert the presidency of Israel in 1952. He turned this down due to his admitted naivete at politics and his belief that his work in physics was much more important and would last much longer than any contribution he might be able to give as a president of a country he never set foot in.
