“Britain, of course, has had a Jewish prime minister.”
Well, that’s not exactly true, if you’re thinking of Benjamin Disraeli. He was born into a Jewish family, but at the age of 13 his family fell away from the Jewish faith.
For the remainder of his life, Benjamin was a practicing member of the Anglican church, which probably accounts for much of his political success in that country.
Do not confuse ethnic extraction, and religious belief. It is a mistake that is commonly made rather like saying all blacks are Southern Baptists (which they are clearly not).
Interestingly, Alexander Hamilton probably had more of a Jewish upbringing than Disreali. He was tutored in a private Jewish school in St. Kitts. He had to go to the Jewish school because the Church schools didn’t accept him due to his unmarried parents.
