Jeruselum is not "deep into Palestinian terriroty". Even before the '67 war it was a divided city, half in Jordan, half in Israel. Your basic point is well taken though, as the top of the wailling wall, which the pope visited, is a Mosque that has been the source of violance for those visiting the wall in the past.
I suspected the Pope might be going deep into Palestinian territory while visiting Jerusalem. I certainly did not mean that Jersualem was Palestinian territory!
