Fatah spokesman Osama Qawasmi said "resistance is a legitimate right of the Palestinian people for liberation from Israeli occupation for and achieving their goal of independence and the establishment of a Palestinian state with its capital in Jerusalem."I wasn't sure if this was a PA or Fatah statement, but now I found it on the official Fatah Media website.
The site says the same words pretty explicitly elsewhere, for example it has a history of Fatah that says:
Fatah is characterized by its flexibility and pragmatism, adopting armed struggle when needed, and political action when necessary.That same document sure makes it sound like the goal is still to destroy Israel, although I'll need a native Arabic reader to confirm that to me. (For example, it seems to have a problem with Jews settling in - the Negev.)
