Did he ever say who these "leaders of the Jewish community" are?
The comment perpetuates a stereotype of Jews as a unified bloc steering the world in their interest and against everyone else's.
I didn't reach that conclusion from reading just that one sentence that the article quoted. Is there a copy of the entire speech this guy gave?
No. That's a sign that he's engaging in anti-Semitic demagougery. He doesn't actually name names and discuss who does and doesn't support the war--he just asserts that the ONLY reason that we're going to war is because the damn Joooos told us to. (Yes, he actually said THAT as well. I'll hunt up the quote.)
