Book excerpt: For decades, we've been shocked by images of violent clashes between Israelis and Palestinians in the West Bank and Gaza. But for all their power, those images leave us at a loss: from our vantage at home, it's hard for us to imagine the struggles of those living in the midst of the fighting. Now, American - born Israeli David Shulman takes us right into the heart of the conflict with Dark Hope, an eye - opening chronicle of his work as a member of the peace group Ta'ayush, which takes its name from the Arabic for ''living together.'' With Dark Hope, Shulman has written a book of deep moral searching, an attempt to discover how his beloved Israel went wrong - - and how, through acts of compassionate disobedience, it might still be brought back.
