Being anti Israel isn't being anti Semitic, Palestinians are semites and Israel is committing genocide against them.
Dancing Israelis sent by mossad to film the event is proof enough. Insider trading before 911 is proof enough, also Larry Silverstein investment and insurance payout is proof enough, he is also a jew and a zionist. Israel need the US to go fight its wars for them in the middle east, so there's motive. All roads lead to Israel.
