If you want to know one major reason the Israeli Palestinian conflict has not been not resolved, you can watch this video.
The video shows a recent Fatah rally. The moderator first states, "Our war with the descendants of the apes and pigs (i.e., Jews) is a war of religion and faith."
Then the moderator invites the official Mufti of the Palestinian Authority Muhammad Hussein to address the gathering. He tells the crowd and quotes from the Hadith (the sayings of Mohammed):
"The Hour [of Resurrection] will not come until you fight the Jews. The Jew will hide behind stones or trees. Then the stones or trees will call: 'Oh Muslim, servant of Allah, there is a Jew behind me, come and kill him.'"
Negotiating teams from Israel and the Palestinian Authority have been meeting in Jordan for peace talks. According to some reports, there might be a breakthrough. But with official statements like this, it's hard to see "peace" breaking out any time soon.
The video released by the Palestinian Media Watch. PMW regularly reports on the official TV of the Palestinian Authority and documents what few in the West get to hear for themselves.
