Bin Laden is emphasizing Palestine and its liberation. In order to be liberated, he accuses fellow Muslims of allowing Palestinians to die. The solution, as he sees it, is to attack fellow Muslims in order to liberate Palestine. The question is why he shifting to an emphasis on Palestine, and not the liberation of the Holy Land? Is it because he knows now that he can not win in Iraq now that AQ is on the run, and traditionally, Palestine was a rallying cry amongst Muslims worldwide? I think so.
