While I am mentioning Middle East News Watch, here is a video they put on YouTube showing the goals of the greatest proponent of Palestinian Arab nationalism. Helpfully, he says it in English:
If Arafat himself was not interested in a specifically Palestinian Arab state except as a means to destroy Israel, why should we think that any other Arab leader has any different goals?
(The person next to Arafat is Uri Avnery, in his first meeting with Arafat. Do you think he objected, or that he even mentions this in his writings as a purported "peace activist"?)
