You want two states? You get a gold star! But it's one state right now, folks. A Washington Post piece on a baptismal site for Christians in the Jordan River in the Occupied West Bank quotes only Israelis, Gidon Bromberg, and Eli Dror of "Israel's Nature and Parks Authority", and generally treats the site as part of Israel:
Israeli authorities vigorously dispute the claims of unhealthful levels of pollution at the sacred bend in the Jordan. They rushed this week to reassure pilgrims about the site, which is a major draw for the more than 2 million Christians who visit Israel each year....
Israel's Tourism Ministry has invested millions of dollars recently to renovate the site, which is located in an Israeli military zone pocked by mines and traced by barbed wire.
Update: I stated that the piece never mentions the occupation. Wrong. I missed this line; it ain't much, but apologies to the Post: "In July [the Jordan]... is a slow-moving body of cloudy, greenish water narrowly separating the Israeli-occupied West Bank from Jordan."
Can Palestinian Christians from Jaffa or Bethlehem visit the sacred place?
Christians from Jaffa could visit if they traveled on the Jewish-only roads that the colonists use in the occupied territories. If they are stopped by the military, however, they could be turned back with no explanation. The alternative would be to take a Palestinian taxi from any point where Israel proper ends and the occupied territories begin. For example, in the Jerusalem area, that would be the Qalandia checkpoint on the Jerusalem-Ramallah road.
Christians from Bethlehem, would not be allowed to visit, unless they had a special permit. Bethlehem is under a military occupation as is all the land in the West Bank that was occupied in 1967. But, such travel permits, especially for a visit to an historic site are almost impossible to get. Visiting one’s family is not considered by the military to be legitimate enough a reason to request a permit, so I don’t see how such travel could be authorized.
