The big story about the Fatah congress is not whether or not it will give up the "right" of armed struggle. Rather, the problem seems to be, as related below, that Fatah is preparing two documents. A document for external use that calls for a two state solution, and an internal document that reportedly calls for elimination of Israel and implementation of a so-called "One State Solution" as its real and only goal. Here is what Fatah plans:
Article 22 calls for: "objection by force to all political solutions that are offered as an alternative to the extermination of the occupying Zionist entity in Palestine and all the projects that aim for the elimination of the Palestinian problem, or seek to internationalize it or put an outside custodian on its people from any possible party."4 This article is in contradiction to the call in the Political Program for greater international involvement in the problem and its welcome for the involvement of international forces in Palestine.
Article 9 states clearly that "the liberation of the Holy Land and the defense of its holy sites (that are forbidden to infidels) is an Arab, Muslim, and humanitarian duty."5
...
Article 13 calls for "establishing a sovereign democratic Palestinian state on the entire Palestinian territory that will preserve the legitimate rights of the citizens on the basis of justice and equality without discrimination on the basis of race, religion and belief, and Jerusalem will be its capital."7 While the Political Program lists the "one-state solution" as an option in case the "two-state solution" fails, the Internal Order document mentions the "one-state solution" as the only solution.
Article 17 says: "The armed popular revolution is the only inevitable way to the liberation of Palestine."8
Finally, Article 19 notes: "The armed struggle is a strategy and not just a tactic and the armed revolution of the Arab Palestinian people is a decisive factor in the war of liberation and the elimination of the Zionist existence, and the struggle will not end until the elimination of the Zionist entity and the liberation of Palestine."9
