Well, it's not anti-jewish because it is perfectly possible to be jewish and not to be a zionist: for example, my father. It is even possible to be an aetheist and be a zionist. Zionism is not based on religious belief per se, it's based on blood--on the posession of Jewish blood!
The Israeli state IS the result of Zionism and US support. Although the Israeli state would like everyone to believe that being opposed to Israeli policy is the same as being an anti-semite, this is not the case. The greatest dissension on this very issue can be found in Judaism itself.
