I wasn't arguing for a strict "difference"--I was arguing for the coherence of holding these two partly or (only seemingly) contradictory positions at the same time. You've labeled these stances as "being a Zionist" and "not supporting Israel [in its present actions]." So if it's possible to be a Zionist and not to support Israel [again, in its current manifestation, with its current practices], then there does seem to be a distinction between being a Zionist and supporting Israel. It might not be as "clear" as the shah made it out to be since it could be a kind of inner tension, or a historically contingent one, etc.
I thought 3Ls didn't even pretend to study. Or did you mean your last finals for the term?
