TMB – Kissinger is an extreme example. One could even make a case that he hates being Jewish so much that he’s not really playing with a full deck. (We know now that Nixon wasn’t.) He also didn’t grow up in the US, so it’s hard to compare him to American born politicians. Believe it or not, it’s not against the law (or halacha either) to be a Democrat. It doesn’t automatically make a politician anti-Jewish. To make a case for that you have to quote specific issues.
Kissinger is a bad egg, and the world would have been better off if he had decided to become a dentist.
