Hashem Himself called the Jew-killers the "Assyrians, Rod of My Anger", and the Jew-killer "Nebuchadnezzar My Servant", and states throught the Tenach that He would use the Gentiles to harry the Jew back to the Land. Rambam states that Hashem will appoint a leader like Haman to force the Jews to repent, part of which is returning to the Land. Does that make Hashem Himself an "antisemite"?!
Paul's aid says he never heard him say anything antisemitic, and like most qualified MDs who are trained to never profess any racism, I doubt he would lapse in to that.
As Paul for wanting the State of Israel to disappear, all gentile politicians (including Gingrich, Sanitorium and the Mormon - but maybe not Palin!) wish that would happen! "For the Jewish People to survive, the Jewish State as currently constituted must disappear. The biggest enemy of the People of Israel is the State of Israel!" (Prof Paul Eidelberg!)
Chaim said in 2000 that all Bush would have to do to be a great president would be not to help Israel and not to hinder her ie not to get involved at all. Like an idiot like his father, he did get involved, and like his father he went down in history as a middling/mediocre US president.
I think a President Paul would be clever enough to learn that lesson, and he would not get involved with Middle East politics at all, which is the professed main plank of his foreign policy!
