Debka is not credible on most things, but perhaps on baseline intelligence issues, they are.
I think another factor is that Arafat is very old and apparently suffering from something degenerative neurlogically, if the reports I have heard are correct.
I think he will try to restart his war, like that crazy rebel in "100 years of Solitude" who spends his whole life in rebellion, but never really hasa clear reason to do so.
