At the age of 50, the PLO sent this guy, one of Arafat's cronies, to Arizona State to take some Master's level courses on using map-drawing software, for use in constructing maps for negotiations. The guy is no recognized "geography researcher", he is just one of the PLO propagandists who spouts to audiences what he's told to spout. He is no bonafide "expert" or "researcher" on anything. Just a PLO draftsman trained to make PowerPoints and maps for their propaganda machine. Israel is finally fed up and dealing the PLO hacks out of the game, they haven't negotiated in good faith for 17 years, whether the Israeli government was left,right or center. Time to send them all back to Tunis and start over. With Abbas refusing negotiations, Obama has no legal basis under US law to allow the PLO to maintain its US offices and travel permits. Israel is just "helping him obey US law".
