OFRA — In a metaphor its opponents may relish, the Israeli settlement movement finds itself mired in a sewer. The Ofra settlement possess a state-of-the-art waste purification plan, but no one can use it because the Palestinians say it's built on their land. So it lies glimmering and white and locked up in the verdant riverbed. The matter, legally and otherwise, remains in the crapper, with Jews and Arabs destroying the environment they unhappily share.
