Of course this website is jewish in origin, so it has no credability whatsoever,
I'll tell you why it has little credibility to me.
Their list of links consists almost totaly of Hasbara sites, from Memri to Daniel Pipes, from ICT to Camera.
Missing are any links to Israeli sites like Btselem or Peace Now, let alone anything from the Arab perspective.
Apart from the links, they have a history of Israel.
Here's the list for a certain period:
8th-16th centuries, Islamic conquest and expansion
Continuous Jewish Presence in the Holy Land (Samuel Katz)
Continuous Jewish Presence in the Holy Land (Peters)
The Qur'an (Koran) & institutionalized anti-Semitism
Religious Persecution of Jews by Arabs
Throwing Stones at Jews is based in Ancient Islamic Ritual
Forced conversions in the Islamic conquests
The forced conversion of the Jewish community of Persia and the beginnings of the Kurds
An appeal to Moslems of Jewish descent
Non-Arab and/or non-Muslims in the "Arab" world
The Islamic claim to the Temple Mount is very recent, since 1930
The name Al-Quds is an abbreviation for "The Jewish Temple"
8th - 16th century history of Israel, and they have no mention whatsoever of the crusades. Plenty about Islamic persecution of Jews, but nothing about the more widespread and severe Christian persecution of the Jews.
It's a propoganda site, and has about as much credibility as
