So, some context - this group is called "Neturei Karta". They are Anti-Zionist in the sense that they believe that Jews aren't allowed to form a self governing state until the Messiah arrives and will rule in god's will. The Palestinians themselves is meaningless to them (much like Iran's Anti-Zionist. As in, their leader actually met with the Iranian president some years ago). This is a more extreme form of the belief that a secular Jewish state has no right to exist, which in itself is a more extreme form of the belief that a secular Jewish state has the right to exist only to act as a platform for a religious Jewish state. The latter ideology is shared by a large part of the current far right government of Israel.
