OP is talking about American's here. AIPAC is made of and paid for AIPAC, like other political packs or other American groups. AIPAC is just Americans, doing the American political thing.
AIPAC is mostly funded by Zionist Jewish billionaires[1]. Characterizing this as "Americans, doing the American political thing" conflates normal Americans with Zionist Jewish billionaires. They are not the same thing.
