PLO-Fatah never had a problem with Hamas attacks against Israel, or with its annihilationist ideology as regards Israel. This ideology is shared by PLO-Fatah and is widely popular among the Palestinians. Consequently not only did the PLO-Fatah never prevent Hamas from attacking Israel, it collaborated with Hamas in attacking Israel and did so while disseminating Hamas's genocidal ideology throughout the PA. PLO-Fatah did crack down on Hamas when it felt that Hamas was threatening its grip on power, but in all other respects, it supported Hamas - and continues to do so.
