This is so reminiscent of Arafat's spiritual forefather, Adolf Hitler, during his own final days. From Joachim Fest's biography,
Hitler:
Physically, he presented a dreadful sight. He dragged himself about painfully and clumsily, throwing his torso forward and dragging his legs after him from his living room to the conference room of the bunker. He had lost his sense of balance; if he was detained on the brief journey (seventy-five to a hundred feet), he had to sit down on one of those benches that been placed along either wall for this purpose, or else cling to the person he was talking to... His eyes were bloodshot; although all documents intended for him were typed out in letters three times ordinary size, on special "Fuhrer typewriters," he could read them only with strong glasses. Saliva frequently dripped from the corners of his mouth.
These are the visible outward signs of demonic possesion that Arafat suffers from just as Hitler did.
