One of the most intractable problems of the Middle East is the relationship between Israel and Palestine. It's always been problematic and it always will be. I doubt that the problem will be resolved, at least any time soon.
I went to Bethlehem from Jordan three years ago, travelling into the Palestinian territory via the Allenby Crossing via bus, as a journalist. I was with several coach loads of Palestinians going to Bethlehem to attend a conference on Palestine- or at least to obtain a visa so that he/she could enter the Palestinian territory in the first place. What an experience.
