Abu Mazen is a habitual liar: since his early and later days. He has been saying that Israel has allowed all Palestinian members of Fath to attend the conference of the movement. He is lying of course. Israel has only allowed the Dahlanist members of Fath to enter the West Bank to attend the conference. Fath regional leader in Lebanon, Munir Al-Maqdah, for example, has been banned by Israel because he has voiced opinion in support of the right of return. I strongly believe that you can't oppose the Israeli occupation of Palestine without opposing its arm: the Fath movement.
