I don't agree with you about the word Zionist. Many, many Jews are not Zionists. But it is the Zionist agenda of the Israeli government that causes problems.

As for whom Hart was talking about with that quote, it would be a waste of his breath for him to only be talking about Jews, or even Zionists, for that matter. Yes, Israel and the pro-Zionist lobby are a very big problem for any US government that might want to use a balanced approach in the middle east. But dispite appearances, the middle east is a very small part of the world. The headaches faced by politicians who have to deal with lobbies seeking preferential treatment for their countries of origin are huge, and to only address one lobby, however persistant, powerful, and influential it may be, is to not really address the problem.
