Mahmoud Abbas is the President of the Palestinian Authority. Both he and his ruling party, Fatah, have repeatedly argued that they only support "peaceful resistance" against Israel. When Palestinians commit murderous assaults against Israelis, they call it a "private" and "spontaneous natural response" to "Israeli aggression."
But are the attacks unplanned, private and spontaneous?
This one minute video produced by The Israel Project tackles the question. They have titled it, "Cause and Effect."
The Israel Project, producer of the embedded video, describes itself as "a non-profit educational organization that provides factual information about Israel and the Middle East." Its official website is http://http://www.theisraelproject.org
